The Plastomatic series of relief valves features a solid, nonsticking PTFE shaft passing through three U-cup seals with a proven, high performance relief valve providing rugged dependability for acids and other highly corrosive liquids.
Angle and in-line designs for corrosive chemicals, water and ultra-pure liquids
True Blue ® Relief Valves provide smooth, sensitive operation to help you manage pressure "upstream" of the valve.
This valve design serves many functions:
Preventing overpressure conditions in vessels and piping systems (relief valve).
Providing by-pass flow relief to avoid pumping problems such as deadheading (pump bypass valve).
Maintain backpressure in a piping system (backpressure regulator).
Enhance pump performance by maintaining backpressure on the pump outlet (pump backpressure valve).
Prevent gravity-induced siphoning through a pump, opening only when the pump is on (anti-siphon valve).
