FAQ

About fire valve is gate valve or butterfly valve problems?

Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.

What's the difference between a soft seal gate valve and a hard sealed gate valve?

The difference is that the form of the gate seal surface is different.General gate valves are generally leaking, easy to rust and other phenomena. Soft sealing gate valve (elastic seat sealing gate valve), gate material for cast iron lining rubber, overcome the shortcomings of the general gate valve, such as poor sealing, elastic fatigue, easy to rust, etc.. Soft sealing gate valve is a new product of the traditional gate valve.

What's the meaning of the gate valve model z41x 16Q?

Gate valve (Z) flange connection (4) wedge type single gate (1) rubber soft seal (X) -16 pressure) (Q)

Why does the centrifugal pump start and stop in the case of closing the gate valve?

The centrifugal pump starts and stops in the case of closing the pump outlet valve. Start off the pump outlet valve is to reduce the starting current, stop when the pump is closed, the outlet valve is to reduce water hammer, prevent blade from bad.

What does gate valve Z44T-10-200 code mean?

Acid resistant alkali valve gate valve

A products have few connections and good overall steel quality.B closure speed is fast.C opening limit mechanism is convenient, flexible and precise.

What is plug welding gate valve?

Socket welding valve refers to the use of socket welded connection valve.Simple socket welding is to insert the pipe into the gate joint to weld.The form of socket welding is mainly used for welding small bore valves and pipes, fittings and pipes. Small caliber pipeline wall thickness is thin, and error prone edge ablation, butt welding is difficult, more suitable for socket welding. In addition, the socket of socket welding has reinforcement effect, so it is also used under high pressure. But socketweld also has disadvantages, one is the stress condition is not good after welding, easy welding penetration, pipe inside a gap, so should not be used for piping system of crevice corrosion sensitive medium pipeline system and clean high requirements for socket welding. In addition, ultra high pressure pipeline, even small caliber pipe wall thickness is also very big, can use butt welding connection, as far as possible to avoid socket welding.

What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?

Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
