Q:What is the difference between Z41X gate valve and Z45X gate valve?

There is no difference in function. The two models are mainly made of different sealing materials,

Q:How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.

See, you choose 100 of the pressure is not high, you can not flange

Q:Which is the most expensive, check valve and gate valve?

In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124

Q:Stainless steel gate valve DN150 200300 weight, who knows?

Valve selection of different driving methods, connection forms, structural forms, nominal pressure, sealing surface materials, lining materials, valve body material will affect the weight of the gate valve more or less, it can not be generalized.Take my commonly used Z41H-16P (i.e. PN1.6MPa) series stainless steel gate valve as an example, and the weight of DN150/200/300 is 134/192/379kg. Of course, different manufacturers may vary in weight, but not much.I hope I can help you.

Q:What valve is z45w gate valve?

Z = gate valve4 = connection: flange5 = structure form: dark rod typeW = sealing surface material: same as valve bodyDetails: JB/T308-2004 valve model preparation methods

Q:Does the tap belong to a stop valve or a gate valve?

If it is about to pull open and close, it is cock valveIf it is rotated up and down, it is a stop valve

Q:Function of signal butterfly valve and gate valve

The signal butterfly valve applies to petroleum, chemical, food, medicine, papermaking, water and electricity, ships, water supply and drainage, smelting, energy and other system pipelines. Available in a variety of corrosive, non corrosive gases, liquids, semi fluids, and solid powders.

Q:Fire protection gate valve from the wall how many distance there is no regulation?

1 meters away from the wall, leaving the maintenance and replacement distance

Q:What does "Z45W-10T" mean?What does each letter stand for?

W is the seal material or lining material code, the valve sealing material is the valve body material, the valve sealing surface material code with "W" said, here stands for brass;The 10 is the pressure code, which stands for PN10, which is often called 1.0MPa;

Q:What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve

Yes. Globe valves and gate valves are indeed common in certain piping and operating conditions.
