Flow-Tek Pressure Relief/Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that can fulfill either of two separate functions.

When installed in-line, it sustains minimum pre-set, upstream (back) pressure regardless of fluctuating flow or varying downstream pressure. When installed as a circulation valve, it relieves excessive line pressure when above maximum pre-set.

• Prioritizing pressure zones
• Ensuring controlled pipeline fill-up
• Preventing pipeline emptying
• Pump overload & cavitation protection
• Safeguarding pump minimum flow
• Excessive line pressure protection

Pressure Relief Valve is a hydraulically operated, pilot-controlled, modulating valve designed to maintain constant upstream pressure within close limits. This valve can be used for pressure relief, pressure sustaining, back-pressure, or unloading functions in a by-pass system.​
