Differential Pressure Sustaining Valve Bermad FP 436

The Model FP 436 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.

Features:

• Hydraulically powered valve design
  – Closes drip tight time after time
  – Eliminates jamming problems
• Hydro-efficient body design
  – Wide rangeability
  – Unrestricted flow path
• One-piece molded single moving part – No maintenance required
• Simple design – Cost effective
• Factory pre-assembled trim – Out-of-box quality
• In-line serviceable – Minimal down time

Typical Applications

• Pump overload & cavitation protection
• Safeguarding pump minimum flow
• Emergency filter by-pass
• Foam recirculation; maintains required foam pressure
• Balancing between circuits in systems

Operation
The Model FP 436 Differential Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated, control valve that sustains minimum pre-set, differential pressure between two points such as pump suction and discharge, filter upstream and downstream, etc.
