Anti Cavitation
WW-720 – Sigma EN ES Pressure Reducing Valve
The Model WW-720 Sigma EN ES Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure.
Valves can be fitted with multiple options such as V ports, single or double cavitation cages for superior cavitation protection & regulation and control.
