Two position switch action is mainly used in the water supply system of large generator sets. It is an important equipment to prevent boiler feedwater pump vaporization and is also one of the key regulating valves in power plants.

It is also commonly used in high-pressure differential two position control applications such as petroleum and chemical industries.

characteristic

Ø Cast straight or forged straight or angular valve body

Ø Sleeve components can be selected as balanced or unbalanced

Ø The throttling surface is separated from the sealing surface, and the surfaces of the valve core, valve core sleeve, and throttling component are treated with nitriding hardening

Ø Fluid channel labyrinth multi-stage throttling, constantly changing fluid direction, controlling fluid velocity, preventing cavitation damage, allowing pressure difference up to 30MPa

All valve components can be quickly disassembled
