Block valve

Block valve

The hydraulic test plug valve, a special-purpose valve for power plants, was domestically pioneered by our company. Its function is to block the pressure test medium when performing overall hydraulic tests on superheaters and reheaters after boiler maintenance. During normal unit operation, by replacing the internal components of the valve, it can be used as a flow-unobstructed pipeline, thereby simplifying the pressure testing process and improving unit operating efficiency.

Block valve

The water pressure test plug valve, a special-purpose valve for power plants, was domestically pioneered by our company. Its function is to block the pressure test medium when the superheater and reheater undergo overall water pressure testing after boiler overhaul. During normal unit operation, by replacing the valve internals, it can be used as a pipe with no flow resistance, thereby simplifying the pressure test process and improving unit operating efficiency.
