Pressure Reducing

WW720-X – Sigma EN ES Pressure Reducing Valve Double Chamber

The Model 720-X Double Chamber Pressure Reducing Valve is a hydraulically operated control valve designed to regulate downstream pressure to a constant, regardless of flow rate or inlet pressure.

The double chamber design—complete with the three-way positioning pilot—enables the valve to go to 100% open position without the risk of hydraulic lockout. The double chamber design makes the valve extremely responsive regardless of differential pressure.
