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.

FAQ of pipeline ball valve-reduced bore:
Q1:I can’t find the type of steel check valve which I need. what can I do?
The chart above only lists out some common composition of steel check valve parts.We may provide other different parts material composition according to the customer's request or the actual valve working condition.
Q2:Which certification do your products pass?
Our products are in accordance with ISO 9001、ISO 14001、API 6A、API 6D、TS CE、API607/6FA/BS6755.
Q3:How can I place an order?
The only one thing you should do is to tell us the sepecification about type 、quantity and mode of transportation, then we will send you quotation within 24 hours.
- Q:Check engine light came on. Had a diagnostic exam run. EGR Valve is gone. Do I REALLY need to replace this valve, or will the car run just fine without it? 1999 Chevy Malibu.
- EGR(Exhaust Gas Recirculation) Valve recirculates the exhaust gas back to the intake. The car will run without it but it might miss and it will most likely effect your gas mileage. EGR valves are not 5 dollars, thats a pcv valve. One for your car is around 140 dollars. If you have the money then replace it...eventually carbon deposits will build up.
- Q:Compare and contrast stenosis and regurgitation (insufficiency) in terms of the functional abnormality associated with the valve leaflets and their effects on hemodynamic parameters such as stroke volume.

- Q:1st valve: this valve used to never cause me trouble at all. THen, suddenly it would stick at the end of the press. I took it home, washed it, cleaned out the casing with the casing brush, cleaned out the holes with a mouthpiece brush, and wiped it clean. Then, i put a bit of oil and it worked fine. Then next morning, i took it out for a second and found it was sticking again. It worked fine afterthat, but why would a valve to that?2nd: this valve is very troublesome. It's sticky for no reason. i did the same thing as the first, but it stayed stuck3rd. Weird valve. One day, i dropped my trumpet (not like down the stairs or anything, just while sitting) and this valve just messed up. What happened, was that when the valve was screwed in all the way, it would be stuck. however, when i unscrewed halfwayor a little less it worked amazingly well. Can a slightly unscrewed valve affect your playing (aside from the clicking noise). Can a valve get dented, causing this?
- I think the reason why your valves are sticking is because they are building up sludge from being oiled too much, and yes, that does happen frequently. Remove the valves carefully, wipe them off thoroughly with a clean cloth, replace them correctly, and lightly oil them. Then try pushing the valves a bit before playing.
- Q:So I just got mu egr valve on my car replaced a year ago. Now it needs replacing again!? why might this be? shouldnt it last longer?
- Your EGR valve is not likely to be defective. Test it to make sure it's defective before you have it replaced. Just because a code reader or scanner reports an out of range reading, that doesn't always mean that the sensor or component is bad. All it means when a code reader or scanner reports an out of range reading it that there is a problem somewhere in that circuit. To test your EGR valve, or any other for that matter, just search the internet for how to test a ______ whatever.
- Q:Also, Is a pneumatic control valve an ATC or an ATO; is it a FO or FC valve?
- THere are a large number of types of valves; ball, gate, globe, needle, etfc. I suggest you look up valves on wikipedia. ATO = air to open; the valve has a pneumatic operator with a spring returning it to closed when the air pressure is removed ATC is the reverse FO = fail open; if the actuator fails the valve will be open. Actuators are made ATO, ATC, and air to move either way [no spring]. The latter would be your FLP. Control valves, by which I mean a proportioning valve or valve with a variable open area, with a 3-15 psi control input, are usually ATO.
- Q:my pcv valve tube is broken in half I replaced it with a rubber hose does it have to be whole
- no, i'm prety sure the pcv valve is to help the engine run smoothly. or something that has to do with the engine, i really dont think that is related to the tramsmission
- Q:How do you take out a valve stem?
- A valve stem and valve stem cap are two different things. If you have a good valve stem, you do not need a valve stem cap. People just use then for safety. You remove a valve stem, with would you believe, a valve stem remover, or some caps have a two pointed top that will remove the stem. Now where to buy them, most old fashion gas station, auto parts, or bike shops, even WalMart.
- Q:After shutting off the hot and cold water lines to my washer to remove the unit from my laundry room i noticed a small leak coming from the hot water valve as if the valve is not completely closing. The valves themselves should be roughly 10 years old and were extremely tight when attempting to close them, my question is how big of a job is this to replace the water valve? Is it as simple as turning off the main water to the house and replacing the valve or are these typically soldered on? Currently i just ran the hose for the hot water to the drain line to prevent water from leaking onto the floor so is this something that is a fairly non issue once i hook the lines back up to the washer and turn them back on? Or is this something i should get addressed asap?

- Q:Is a Head gasket the same thing as the valve cover gasket, on my honda civic si?
- Depending on the material..If it is cork..you should change it every time..if it is neopreme..it can be reused...but what I don't understand is why do them seperatly..you have to take the valve cover off to replace the head gasket.
- Q:wife died at 40 still awaiting results of exsaminers report. Can CPR be given to some one with two artificial heart valves mitral and arotic? She the person administering CPR be aware that they are in the heart...
- Yes, and it doesn't matter if there are artificial valves or not. The thing about CPR is that it's only done for someone who is actively trying to die. The alternative to doing CPR is to let someone pass away, which is not usually the best course of action (unless they have a terminal disease and have asked not to be resuscitated.) If you are asking whether the presence of heart valves excuses someone from NOT doing CPR... then no. If you are asking whether heart valves + CPR and a bad outcome is because CPR should not have been done, then no to that too. The right thing to do for someone who is pulseless is to start CPR, call 911 and get more definitive treatment on the way. CPR is not going to revive someone - it is only a bridge until a defibrillator and/or cardiac drugs are available. I'm sorry that you lost your wife at such a young age, and I hope you find the answers you are looking for.
