产品详情
The multi-stage pressure reducing regulating valve (high-pressure differential regulating valve) effectively controls the fluid flow rate through the valve components, thus significantly reducing noise and preventing liquid cavitation. Multi stage pressure reducing regulating valves are mainly used in environments with cavitation, high noise, and high fluid pressure differentials.
