Q:What is a protective gate valve? What is gate valve knowledge?
Explosion-proof valve products, is a kind of safety valve can eliminate the shock wave which can stop the water hammer shock wave, it is a product composed of multiple sets of safety,
Q:Soft sealed gate valve and hard sealing gate valve which good?
If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.
Q:HVAC design, why is less than DN50 of pipe gate valve and cut-off valve,
I don't know why it was designed. Provide you with some information you refer to, I do not know if it works for you1, stop valve and gate valve are very expensive, more than DN50 can make a lot of money2, butterfly valve is only more than DN50, no small, there may be, but I almost can not see the market.3, like DN150, DN200 such cut-off valve, gate valve is very large, and the butterfly valve is relatively light, installation can save the cost of the block, the valve itself saves too much money.4, but most of the butterfly valve used for a long time are closed.
Q:What is the allowable leakage rate of the gate valve D?

According to JB/T308P stands for Cr-Ni stainless steelR stands for Cr-Ni-Mo stainless steelCr-Ni stainless acid resistant steel has CF8, CF3, F304, F304L, which applies to the medium of work, such as nitric acid oxidation acid.Cr-Ni-Mo stainless acid resistant steel has CF8M, CF3M, F316 and F316L, which is suitable for working medium, such as acetic acid and reducing acid.
Q:What is wire feed gate valve? What do you say in French?
Point to the wire gate valve. Refers to the valve body with internal thread or external thread, and pipe thread connection.
