The sealing surface of the valve is often corroded, eroded, and worn by the medium, making it a vulnerable component of the valve. For example, automatic valves such as pneumatic ball valves and electric butterfly valves have frequent opening and closing and fast opening and closing speeds, and their quality directly affects the service life of the valve. The basic requirement for valve sealing su...

Selection principles 1. Safety and Reliability Industries such as petrochemicals, power plants, and metallurgy demand continuous, stable, and long-term operation. Therefore, the valves used must exhibit high reliability and safety factors. Valve failures should not lead to major production safety incidents or personal injuries, meeting the requirements for long-term operation of the facilities. 2....

In industrial production, drain valves play a critical role by eliminating condensate and superheated steam from pipeline systems to maintain normal operation. However, during cold winters, the moisture in pipeline systems is prone to freezing, resulting in the failure or damage of drain valves, thereby affecting the normal operation of the system. Therefore, implementing effective anti-freezing m...
