About Product
A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and PTFE butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.
1.Simple and compact construction. Small in size and light in weight. Easy transportation, installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
3. Excellent sealing performance with ZERO leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.

- Q: Where are the valves. And how do I fix it? Will I have to buy anything? I have a 98 Honda fourtrax 300.
- You certain its a valve noise and no longer an exhaust leak up near the head? They can sound very equivalent. If it's a valve noise the very first thing to check for is oil stress. Due to the fact you say it can be good maintained I have to expect you have changed your oil AND filter at the recommended intervals. Let me recognize, i know probably the most prior shadows had a unconventional hydraulic valve procedure where you had to force oil right into a chamber for the lifters. In case you misplaced that oil the lifters do not operate accurately.
- Q: Are these valves are a kind of heart chambers pressure sensors?What is keeping them interlocked 2x2?
- It's all mechanical. The valves are passive things kind of like a screen door. When you push on them from one side they open, when you push on them from the other they close. The valves are assisted by some fibers attached to the inside of the heart similar to the way a screen door is helped by a spring attached to the door frame. It's the flowing blood that pushes the valves open or closed as the heart pumps. The path that the blood follows in the heart as it beats happens to make it so that the valves close two at a time. This is because the heart is actually four separate pumps that work two at a time. There's no direct electrical connection to the SA node. The only way they're connected is that the SA node firing is what causes the heart to pump, causing the blood to force the valves open.
- Q: i have been having these chest pains and i went to the doc. they did an ekg, blood test for enzymes and a echo. Well today i went back for the results of the echo and was told that i had a leaky valve but it was nothing to worry about and that there are just trace amounts of valve regurgitation. Im only 19 and i have no other history of heart problems or diseases should i be worried...they said i didn't need any anti biotics or anything and that it wouldn't kill me just to watch for it as i age into my latter years of life 50-70, but im still kinda worried..anyone else have this? im also pregnant and im concerned as to how this will affect my pregnancy, labor and delivery????
- i have the same problem,they found it when i was 40 and that's been 10 yrs ago.in 10 yrs it has put me in the hospital 4 times.but feel good most of the time.good luck.
- Q: I am modelling the production of phthalic annhydride and my process has a lot of FIC, LIC, PIC notations in circles on the connections. Moreover there are what i think are temprature and pressure notations in a square and a triangle. But most primarily what does a pneumatic valve do?
- pneumatic valve is nothing but a valve which is operated with the help of high pressure compressed air. the can be thought of as an alternative of a metal spring... These could retract valves more quickly and reduce the possibility of piston-valve interference as long as pressure could be maintained. Additionally, the amount of seat tension required to keep a coil sprung valve under control results in greater peak lift loading, with added stress to the entire valvetrain as a result.
- Q: 1995 Yukon need valve lash adj- how and hat tools?
- remove valve covers, watch front left two lifters and turn engine, by bolt that holds harmonic dampener to front of crankshaft, so mark on dampener lines up with mark on front cover. If rocker arms do not move as marks line up engine should be on top dead center number 1 cylinder. Now you can adjust exhaust valves 1, 3, 4, 8 and intake valves 1, 2, 5, 7 [ odd numbers are on the left bank from the front 1,3,5,7 even on the right bank from the front 2,4,6,8]. Adjust by turning nut in rocker arm out until movement is felt than tighten until all movement is gone and tighten one turn more. After done with the first eight valves turn engine over one full turn till marks line up again. Then adjust exhaust valves 2,5,6,7 and intake valves 3,4,6,8 the same way.
- Q: Describe a typical semilunar valve and tell how it works

- Q: I'm trying to estimate the amount of gas lost when a relief/blowoff valve is opened on a pipeline. If I know the valve opening size, pipe size, gas pressure, and the duration the valve is left open. Ex. A 12 inch pipe operating at 400 psi has a 4 inch relief valve that is open for 5 minutes. How much gas has been release? Assume constant flow of gas. Thanks in advance
- Below is one of many sites with software for sizing relief valves. Each relief valve has a specific orifice size usually indicated by a letter such as A, B, C etc. With this and the other information on the gas being relieved you can calculate the rate the valve is relieving when it is open. Note: most of the time you will be in the critical flow range so once the valve is open the flow rate will be constant until the pressure falls and the valve reseats.
- Q: I am looking at buying a 2001 Pontiac Bonneville and the guy said the car's check engine light says it had a problem with the EGR valve and so he bipassed it somehow. He said a EGR valve isn't needed. Is this valve very important or needed? What does it do? Thanks
- If you live in a County that requires emission tests, most likely your car will not pass the inspection. I would have it change it is good for the environment as well as making your car more efficient.
- Q: I own a 1982 Pontiac Firebird base model which has recently started leaking oil from its Proportioning Valve. I have looked all over the internet for a replacement, and it turns out GM has discontinued the part. Now im faced with difficult and risky task of attempting to fix it, or turn it over to a repair shop as a last resort. The valve seems to leak out of a small circle with a hole the size of a needle inside which was covered by a rubber gasket. I have no clue what this does, and how to repair it.
- First up is that the valve is not leaking oil, it is leaking brake fluid. That is bad. The proportioning valve controls the brake pressure to the rear brakes. Most of the braking is done with the front brakes and without the valve you could lock up the rear brakes on medium to hard stops and the rear end could loose traction, that would be a bad thing on a sharp turn. With that said please replace the valve I have never seen a repair kit for them. Have you looked at to GM for the part? They may also have knowledge on a conversion of the master cylinder with the valve built in.
