Q:What does the gate valve 150# mean? Is it stress PN? What's that, PN16 or?It's better to have some specific links, thanks!

150Lb (American Standard pressure value corresponding to the PN2.0)

Q:What is a protective gate valve? What is gate valve knowledge?

Door gate, refers to the design of anti blocking nuclear explosion shock wave from the pipe into the project inside the valve, composed of a valve body, valve seat, valve plate and wave absorbing device, wave absorbing device leakage hole in the valve body, valve leakage hole is a cylindrical hole, wave valve has two door sealing groove between the cylindrical hole and wave valve double seal ring seal, between the valve body and the flange is double sealing ring seal.

Q:What is wire feed gate valve? What do you say in French?

Should refer to the threaded valve. Refers to the valve body with internal thread or external thread, and pipe thread connection. Also called thread valves, threaded valves, valves within the toothFlange gate valve is connected to the flange gate valve, this connection is the most common way.We also introduced a lot of threaded valve, can go to the front pages.The main difference is the threaded valve connectionI only know their English, I'm sorry I can't help youBox thread valveFlange valveThreaded valve, screw connected with the valve, should be said that the former is the most professional.

Q:Z45T-10 what kind of material is the gate valve?

Cast iron, sealed with copper alloy inside. Shanghai Yu Cheng fluid on the professional production of this thing,

Q:What is the difference between an elastic gate valve and a rigid gate?

General rigid gate used in the temperature is not too high, the pressure is not too large occasions, flexible gate used in high temperature, high pressure, or relatively high sealing requirements.Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.

Q:What is the difference between gate valve and gate valve? Is it the same valve?

Gate valve and gate valve are 2 kinds of valves, do not feel like a long name is the same kind, please look at Baidu maps introduced manufacturers.

Q:Gate valve is gate valve, gate valve specifications, model code is generally what?

Gate valve is not gate valve, gate valve does not have a fixed specific model
