Company Profile

V100-SGA Series Anti-Cavitation Single Seated Control Valve (Multi-Layer)

V100-SGA Series Anti-Cavitation Single Seated Control Valve, especially designed for liquid medium of high differential pressure and low flow, is capable of operating in harsh conditions of high differential pressure. It features unbalanced contoured-p plug and high precision adjustment.

The standard actuator configuration is multi-spring diaphragm; other actuator types such as cylinder, electric and hydraulic are also available.
