PRODUCT INFORMATION

WW736 – Differential Pressure Sustaining Valve AS5081 / WaterMark

The Model 736 Differential Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that sustains minimum pre-set, differential pressure between two points, regardless of fluctuating flow or varying upstream pressure.

• Pump overload & cavitation protection
• Balancing between circuits in HVAC systems
• Safeguarding pump minimum flow
• Emergency filter by-pass
