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: what would happen if valve was not adjusted right? and please explain
- it could make a hole in your piston
- Q: I have a 2000 jeep grand cherokee v8 4.7L it has a stuck valve making knocking noises my question is can i still drive it !? or is too dangerous
- For 1 how do you know it has a stuck valve , if you know that you know how to get it unstuck (pb-blaster ) or something like that , or is it carbon holding it open if it is you will need to pull the head becouse the head of the valve will come off and damage the piston and the block , good luck.30 years exp on cars and big trucks
- Q: I somehow lost the valve cap to one of my tires. Do stores sell replacement caps? If so, would a place like Sears or VIP be a good place to look? If not, would a bike tire valve cap work?In the mean time, i took a cap off the fullest tire to put on this one(the lowest) was that good or bad idea?
- Tire Air Cap
- Q: Some trombones have Thayer valves? What are those for compaired to the regular standard open wraps?
- open wrap is a design for less backpressure through the valve,....the thayer valve reduces that backpressure even more. go play different pro horns side by side, vary the brand/valve combinations and see what plays the most free (especially in the low to pedal range).personally i play an old bach 42k and i love it.
- Q: When my son was three I switched Dr's for him. The new doctor said has he always had a heart murmur I said no that's the first I've heard of it so we went for test. Anyway heart specialist did all tests said my son had Bav a valve disorder in the heart. He said it is very common. However everyone I've ever talked to has never heard of it. My question is does anyone have this what is your story and have you had to have your valve replaced. My son is very healthy active I'm just worried. Any help would be greatly appreciated....thank you!!
- A bicuspid aortic valve is not necessarily a problem - a normal aortic valve has three cusps, and your son only has two. Having only two cusps is not a big deal. The mitral valve in the heart naturally has only two cusps, so three cusps are not needed for a heart valve to function. The advantage of three valves is a slight increase in efficiency, but the difference between a normal valve and properly working bicuspid valve would only matter to a professional athlete. If the aortic valve closes almost completely, there is nothing to worry about. Since he has a heart murmur, its possible that it is caused by having only two cusps, but people with three cusps commonly have murmurs. There is no reason to get the valve replaced simply because of only two cusps. What matters is the level of aortic valve regurgitation. If regurgitation is not significant, your son has a normally functioning heart. Even if he had a moderate or high amount of regurgitation, it still might not have enough effect to warrant surgery. There are tests to measure regurgitation.
- Q: I Have a 2001 Honda Accord 3.0 V6. Would a clogged EGR valve cause it to run rough and have problems starting up when it is warm? It also runs hot. I have replaced the thermostat and the cooling fan relay? What could cause all of this? PLEASE HELP!

- Q: I have the correct tools and have done this before. All I want to do is change all three valves that operate the water (hot,diverter,cold). The shower is leaking. I want to change all three valves to stop the leak. I will call a plumber if I can't change the valves or stop the leak. Please tell me what tools I need and I'll begin from there. I have three handles/valves in the shower(cold,diverter,hot).The cold is here # and the diverter is in the center which is here # and the hot is here #. They all line up like this c# diverter# h#. These are how the valves are set up # # #.
- There is not three separate valves, it is basically a manifold with two shut off valves and a mixing valve all combined into one unit. Replacing the whole unit would be the easiest most efficient thing to do. What I'm thinking has happened is that the valves started to leak, and you kept tightening the handles in an effort to stop the flow, thereby stripping the handles, not the valves. Get a faucet handle puller, pull the handles, and remove the valve stems by undoing the packing nuts, there is also a seat reamer tool, resurface the seats and install new washers, buy new handles and you may not have to replace the whole diverter assembly. It will take more time but will be cheaper also.
- Q: Holding my right hand up, I am a newbie :) any help is greatly appreciated.a) Comparing the shape of the valve to a golf tee, what is the correct name for the thinnest section of the valve(the part of the golf tee that goes into the ground)b) What is the correct name for the widest section of the valve(the part of the golf tee that the ball is placed on.c) The cylinder that the valve moves up and down in, is it just called the valve cylinder?d) In the valve cylinder?, how does the widest part of the valve keeps things sealed. Does it use a ring(simmilar to pistons) or is it some type of gasket material or is it just zero clearance metal to metal.e) The section of the (valve cylinder?) that is above the seal point or basicaly where the valve spring and the thinnest part of the valve is, does oil flow through here?f) Do (valve cylinders?) generate enough heat to warrant the need for coolant?Newbie City, I know. Any help is GREATLY appreciated.TY
- a) The very end is the tip. Below that are grooves that the keepers lock into. This is actually the thinnest part. Below that is the rest of the stem. The general name for the largest part in total is the valve head. b) Surface sounds right. Hadn't really thought about it before. LOL c) Valve Guide. These can either be just a plain hole in the cylinder head material, or often they have bronze inserts. Plain Guides are often repaired by a process called knurling. d) Valves seal to the head by grinding each at the same angle, (usually 45 degrees) and then they are lapped which is where an abrasive compound is placed in between, and the valve is rotated. This matches the surfaces more closely yet. The parts that seal are called the valve face and the seat which is actually a separate part that is inserted into the head, and can be replaced. e) Oil is supplied to that general area, by either holes in pushrods that lubricate the rocker arm, or in the case of rockers mounted to a shaft, through the shaft. In the first case, oil is supplied by the hydraulic lifters. In the latter, the shaft pedestals are drilled for oil passages. In both cases, oil is present in the area, but is not applied directly to the valves. In fact, the job of the valve stem seal is to keep too much oil from getting in the guides. f) Usually the coolant flowing through the heads is enough to carry away the heat, although some hi-performance engines employ techniques such as hollow exhaust valves filled with sodium. Most normal valves are solid.
- Q: I had heart surgery a little over a year ago. This surgery gave me an artificial aortic valve in replacement to my real aortic valve. Before this I smoked weed all the time, but now, I 'm on blood thinners, and I'm not sure if it's okay. Is it?
- Definitely not recommended to do any non-doctor recommended drugs while in such a state.
- Q: My brother is 32 years old.He has an enlarged heart ,a murmur,high blood pressure and heart regurgitation.He may be having the valve replacement surgery.I was wondering if anyone has had these things wrong with them and had the valve surgery and did well afterwards.Any information would be very much appreciated.
- Guy I work with just had 2 valves replaced. He honestly didn't know anything was a matter until he collapsed at work. They ran some tests and figured out that was his problem. Talked to him a few days after his surgery and he said he hasn't felt this good in a long time. Its a common procedure nowadays, and your brother should most definitely be in good hands. Keep us informed, and best of luck to you both!
