choose kinds of water valve

The valve that does not meet the corresponding requirements of ASME/ANSI B16.42 or ANSI/AWWWA C504 should be determined by the minimum wall thickness. This minimum wall thickness is determined by the use of design and using these standards. EssenceThe replacement method does not meet the valve of the corresponding requirements determined by ASME/ANSI B16.42 or ANSI/AWWA C504 corresponding requirements. The reduced valve wall thickness between the valve body and the adjacent bolt hole of the valve body should not be less than 25%of the wall thickness required by the neck of the valve body. For the vessel valve coected to the flange coection, if the materials listed in the French standard...

Pneumatic valve is a kind of valve. There will be some problems in the process of use, including the pneumatic valve is not closed tightly, what is the reason for the pneumatic valve not closed tightly? How to solve this problem?1. Incorrect selection of control valve: Different types of custom brass fitting  control valves allow different pressure differences. Sleeve control valves and double-seat control valves allow larger pressure differences than single-seat control valves. Angular stroke V-shaped control ball valves and eccentric rotary valves The allowable differential pressure will be larger. In the case of relatively large pressure difference, reasonable selection is very ...
