In industrial piping systems, butterfly valves, check valves, and gate valves are common valves used to control fluid flow. The sealing performance of these valves directly impacts system safe...
Valve foundation
1. The basic parameters of the valve are: nominal pressure PN and nominal diameter DN
2. Basic function of the valve: cut off the connected medium, adjust the flow rate, and change...
Grinding is a commonly used finishing method for the sealing surface of valves in the manufacturing process. Grinding can make the valve sealing surface obtain high dimensional accuracy, geometric ...
Municipal water systems need durable valves for high flow, changing pressure, and varied conditions. Butterfly valves are popular in medium-to-large pipelines for their compact design, fast action,...
Valve selection principle
The selected valve should meet the following basic principles.
(1) Safety and reliability of petrochemical, power station, metallurgy and other industries require continuo...
Single eccentric butterfly valve
In order to solve the extrusion problem between the disc and the valve seat of the concentric butterfly valve, the single eccentric butterfly valve is produced. Dis...
