Product Description of High-performance pipeline ball valve-reduced bore:
High-performance pipeline ball valve is Raymond(RMD)hightech products,as switch control equipment,it is mainly used in natural gas,oil,gas,liquefied natural gas pipeline transmission system and other industries,its anti-sulfur products containing hydrogen sulphide,impurities and high corrosion are suitable for the long-distance natural gas pipeline.
Design Features of High-performance pipeline ball valve-reduced bore:
Body of high-performance pipeline ball valve is forged structure.The connection type for body and vice-body can be BB(bolted connection)and WB(welded connection).The WB(welded connection)and the LWB(Fully-welded extended stem)structure isadopted for buried ball valves,as shown below.
High performance pipeline ball valve series has the feature of strength, high perfect sealing, maintenance-free, long life and so on. The production of this series ball valve adopts the international advanced ball valve design and manufacturing technology, selects high-quality materials in accordance with the standard selection of materials and combines with advanced materials forming forging technology. At the same time, with the years of ball valve design and manufacturing experience, the use of advanced processing and manufacturing equipment and production and processing technology, through the first-class inspection and testing equipment and instruments, perfect quality assurance management system and excellence in the production of high-performance philosophy can ensure the quality of valves. This series of valve has the performance of a high strength, defect-free forging body, excellent sealing performance, even at maximum pressure difference(full pressure),it will still be able to ensure that seal without leakage, after frequent switching action to realize a safe usage in the transportation of oil, natural gas, coal gas, and other special medium transportation pipeline.
The special structure of valve seat seal of High-performance pipeline ball valve-reduced bore:
Floating structure means seat reciprocally can move along channel direction,so as to guarantee the ball and seat are tightly sealed.
(Ⅰ)Valve seat structure suitable for different occasions and sealing requirements
Valve seat can be designed as a standard single-piston effect and specific dual piston effect,Figure1 shows single-piston effect-inletside seal;Figure2 shows Dual Piston effect-outlet-side seal;Figure3 shows special dual piston effect sealing structure
(Ⅱ)Multi-level structure of the valve seat seal
As shown in Figure4,there are two elastic O-ring in the valve seat ring-ring A and ring B.Sealing ring A spring-loaded through the valve seat so that the sealing surface of sealing ring A tightly fit with ball surface to form an initial seal.When there is pressure in the system medium,the piston force
produced by the piston force produced by the piston effect of size difference makes elastic deformation of the ring A Ershi sealing surface and ball more closely fit the surface to form a re-sealing;meanwhile,due to ring A in the medium resulted in elastic deformation under pressure so that the sealing ring B is also closely fit the surface of ball for the formation of the second stage seal.When the system medium pressure increasing,it will have an enormous pressure in the valve seat ring A and ring B,so that the two seals have a greater elastic deformation,and then the metal valve seat ring surface and the ball surface sealing together to form a third level of metal to metal seal.
(Ⅲ)The assisted valve seat sealing equipment
Based on the actual service condition,medium requirement,sealing requirement,etc.,the assisted valve sealing equipment will be considered to be necessary or not.The assisted valve sealing equipment is a one-way valve installed outside of valve body that can prevent medium leakage and can inject sealing grease into valve body by external force.When the assisted valve seat sealing equipment is required,valve seat ring shall be design and processed with injection grove and hole to connect the assisted valve seat sealing equipments.Such equipment can prevent the medium by the sealing of injection of rease.Refer to Figure5 for reference.
Multi-level structure of stem sealing
Figure6 shows the stem multi-level sealing by adopting"O"ring,flexible graphite and grease injection;"O"ring achieves the first level stem sealing;Replaceable flexible graphite realizes the second level sealing by the compression of packing sleeve and packing flange;And the third evel sealing is realized by installing assisted sealing injection valve to the packing box,and by designing with the injection groove and hole to connect with the stem injection valve,which can inject grease.
Unique and safe seat structures of High-performance pipeline ball valve-reduced bore:
Ball valve fireproof design is implementation of the API607,API6FA standards.According to service conditions and user requirements,ball valve can be designed as a fireproof structure.
(Ⅰ)Fireproof structure of seat
As shown in figure7,there is composite fireproof ring,which are combined with graphite and stainless steel wire in the seat.Once the soft ring is burnt out in case of a fire,the fireproof ring and seat ring will form a piston structure through the spring to load the valve body.That will push and closely contact the metal seal surface of the seat ring to the body surface,So as to prevent a lot of medium from leaking from the burnt place of the seat ring,and prevent the fire from expending.
(Ⅱ)Fireproof structure(body and bonnet)
The seal gasket for bolt connecting valve body and valve bonnet,are used fireproof stainless steel wire and flexible graphite gaskets.Gasket compression load through the bolts and ultimately,ensure the valve body and valve cover between the metal to metal contact,so that the valve can with stand more high load,but also improve the fire safety of the valve.But for the full welded ball valve,the valve body and cover is welded structure,that fundamentally eliminate the possibillity of leakage of the valve housing.Even in the case of fire damage,there will be no leak.
(Ⅲ)Fireproof structure(body/packing and stem)
The body and packing connection gasket adopts fireproof stainless steel wire and flexible graphite gaskets.The stem packing adopts flexible graphite to ensure no leakage in case of fire.

- Q: Hi. I looked at instructional videos for installing shutoff valves and instead of simply unscrewing old valve, the plumber simply cut the copper pipe. Is this necessary? Why can't I simply unscrew old shutoff valves from copper pipe?
- Before you think about cutting the pipe. You should know there is water pressure behind it. You must first shut your water off at the meter. If you opt to take on this endeavor by yourself you have some easy options. There are four types of connections to my knowledge. Soldered is most common and very effective but takes know how. Then there is compression, threaded (which involves sweating a connection on the copper, and then some genius has came out with this new type of connector commonly refered to as shark bite or gator bite (those being the top two leading brands). With these connectors all you must do is put the little plastic insert in the pipe then push the connector on. Ta da! Then your done. I would even bet they make a push on connector with the shut off valve. So to recap. Shut off water, cut the copper and remove burs from pipe, take that piece to the hardware store so you know you have the correct size of pipe fitting. Go home and push it on and then turn your water back on and your done.
- Q: I have checked this and ensured that the flow control is turned on. I have also found that:1. Valve works in manual mode2. Solenoid is getting electricity and water seems to be flowing in automatic mode but nothing is coming out of the sprinkler.I am not sure what could be broken as manual operation works and solenoid sems to be working. Any ideas?Thanks.

- Q: i need to know the setting of the valve and a little advice on the up and down of the valves
- As Bob said, you had probably best bite the financial bullet and get someone experienced to do it. With the bucket over shim designs, the shim you need to change is underneath the bucket, the device that rides against the camshaft. To change the shims, you have to remove the camshafts and when you replace them, you must get them timed exactly right or else you can have pistons hitting valves..not good at all. They put the shim under the bucket to keep the cam from spitting the shims out through the valve cover at high rpms. The older 2 valve 900-1000-1100-1300 Kaws have shim over bucket and can be changed with a special $20 tool, a little screwdriver and small magnet . However, you might consider getting a shop manual and checking the valve clearance yourself. If all are within specs, then there is no need to take it to a shop. My old KZ1000 went something like 110,000 miles and only need two shims changed in all that time, so your bike could very well be ok.
- Q: school starts tomorrow that means having band and i havent played it in 2 months (summer vacation) and i oiled the valves and the 1 and 2 valves are stuck the 1st valve comes up slowly when i push it down but on the 2nd valve it stays down how do i undo this???? thank you
- You could just get a screwdriver and drill it into the bottom of the valve till it comes out. Its not damaging anything because there are no air pipes going through the bottom .
- Q: have a 86 flhtc had new cylinders 10-1 pistons supposed to be 86 cubic inches when i run it up to 90-95 bending valves what can i do to stop bending valves-------HARLEY DAVIDSON
- The other answers are on the right track, but are failing to include the other possibilities. You say you have had the heads done...WHO did the headwork? Were oversized valves installed? What valve springs are you running and were they packed for proper and even seat pressures for the cam lift? Were the valve seats cuts for new valves and if so, was proper valve stem height set? What cam are you running?...What is the TDC lift on that cam? Were ALL clearances checked when the engine was assembled?...Meaning valve-to-valve clearance during valve overlap, not enough clearance and the valves will hit each other...valve-to-piston clearance, this is where the cam's TDC lift specs come into play, if you don't have the proper clearance, the valves will hit the piston........MINIMUM of .060 clearance on both of these checks. What lifters and pushrods are you running?...stock lifters can pump-up at high rpm and lift the valve too much causing it to contact the piston or the other valve. Are you 100% postive you are adjusting the pushrods to their manufacturer's specs...different pushrods manufacturers use different thread pitches that require different adjustment lengths. As you can see, if the engine wasn't PROPERLY built and all clearances checked, you have a MAJOR job ahead of you, this require extensive knowledge and tooling. If you assembled the engine, take it to a reputable performance shop and let them check it out, if a shop did the work, FIND ANOTHER ONE!!! Building performance engines is not easy work and not for the novice.
- Q: what is a silicone purge valve.
- There are a number of things that will Toss out and ERG code on Fords (another reason I will never own another ford as long as I live) Double check all joints around the EGR valve and the tubes that connect too it. You may have a pin hole in one of the tubes or a loose coupler. If everything checks out there. Verify the vacuum line going to the EGR is not cracked, rotted, broken, or clogged. If it is replace the line. Next you need to check and make sure the valve is opening at the correct time. If the EGR is slow to open, becomes stuck half way or is opening to quickly, these will all toss out EGR codes. Then there is the possibility that the tubes for the EGR, or the EGR it's self may be clogged as well. In which case you need to remove them and clean them out. Hope this helps in your trouble shooting. Good luck.
- Q: 1990 Pontiac Sunbird, I took a piece of hose going to the egr valve to try and see if it is working properly, but with car off, I can suck through, and blow out into hose going to egr valve, and it doesn't seem like there's any seal stopping air flow either way...is it supposed to, or what is this supposed to do?
- It would be best if you could test the valve with a vacuum tester but from what you describe it is probably bad. The EGR has a diagram (basically a rubber disc) in it which can go bad when this happens the vacuum from the motor can no longer activate it. The biggest problem you may notice from this is you now have a Vacuum leak causing your motor to run lean. Many people would just plug the vacuum line to the valve to prevent the Vacuum leak and not worry about the valve. If you want or need to keep the emissions working on the car buy a new valve.
- Q: ok im 17 and had really bad chest pains for like 2 years and the dr told me last year my valve was leaking and the pains have been getting worse what should i do?
- Your doctor should have referred you to an heart specialist. Don't be asking kids here, ask the doctor!
- Q: I have recently been diagnosed with Endometriosis within the last 2 years. I have also had Mitral Valve Prolapse (MVP) for the past 10 years. ... Anyways... I was reading in a brochure for Endometrosis that there is a commonality between having those two diseases. If you know of the reasoning behind this I would be very interested in knowing. As I have yet to find an answer yet. I am just curious why having one will give you a larger likley hood to get the other. Thanks for your time and answers!
- You okorder ). It's about how to eradicate endometriosis disease forever. It worked for me, you will see results in only a matter of weeks. Good Luck!
- Q: How hard and expensive is it to replace a pvc valve , hose, filter on 1991 Dodge Caravan 4 cylinder
- The Positive Crankcase Ventlition(PCV) does 2 things, 1.the valve prevents backfire pressure from entering the crankcase(oil pan area), the pressure could damage oil seals and gaskets causing oil leaks. 2. as the engine runs, as small bit of combustion gases slips past the piston rings and into the crankcase, if it does not have a way out it can damage the oil seals. these gases are sent back through the engine and out the exhaust. the hoses just directs the flow of the system. the filter keeps trash from getting into the crankcase. the flow of the system is as follows:filter-hose-valve cover-crankcase- hose- PCV valve-intake manifold-cylinders-exhaust. if oil is developing in the filter, there is a clog in the system somewhere or you have bad rings
