Q:Import electric butterfly valve which brand is more reliable?
Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
Q:How to control the single acting pneumatic butterfly valve?
There are single acting pneumatic head, we must pay attention to often open or normally closed, we must pay attention to.
Q:Check valve; flexible joint `; installation order of electric butterfly valve
Connect the Songjiang rubber joint from the pump outlet. Check the 1 valve
Q:Why anti condensation of aluminum alloy anti condensation butterfly valve?
Anti condensation butterfly valve multi-level unique progressive contact seat design, the valve plate in close contact in the process of gradually seat, ensure good sealing performance while reducing unnecessary torque, and the butterfly plate of stainless steel and the inner parts, thereby prolonging the service life of the valve seat, has strong rust and corrosion function. Torque reduction enables the drive to be lightweight and miniaturized. Unique stem seal prevents fluid leakage.
Q:What are the butterfly valves models?
Divided by way of drive(1) electric butterfly valve(2) pneumatic butterfly valve;(3) hydraulic butterfly valve;(4) manual butterfly valve;In the form of structure:(1) Central sealed butterfly valve(2) single eccentric sealed butterfly valve(3) double eccentric sealed butterfly valve(4) three eccentric sealed butterfly valve;
Q:Buried extension butterfly valve is buried directly, or need to repair the valve well?

Q:What is the effect of nylon coating on butterfly valve plate? Thank you
Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high
Q:What's the difference between butterfly valves and check valves?
Butterfly valve is manual, only switch function.The check valve is an automatic valve, which prevents backflow of the pipe medium.
Q:How does PLC control butterfly valves?
PLC control butterfly valve, usually control pneumatic butterfly valve or electric butterfly valve, see which way you control butterfly valve.PLC control pneumatic butterfly valve, that is, PLC program control, electric control, gas control, gas control butterfly valve;PLC control electric butterfly valve, that is, PLC program control electric, electric control butterfly valve.Ordinary switch butterfly valve is the program control on and off, to the 1 way valve open, to another 1 way valve off.
Q:What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
For clip butterfly valves, there are no flanges at the ends of the butterfly valve. There are only a few guide bolts. The valve is connected with the end flange with a set of bolts / nuts.In contrast, the demolition to facilitate some of the lower cost of the valve, but the drawback is that a sealing surface problems, the two sealing surfaces have to be taken apart.Flange butterfly valve at both ends of the flange, and pipe flange connection. The seal is relatively more reliable, but the valve is of relatively high cost.
