Plastic pressure in-line relief valves are multi-functional, normally-closed valves for system pressure relief, pump protection, enhancing pump performance, by-pass relief, and balancing pressure in a process system.

For anti-siphon applications, Plast-O-Matic series RVDT features a unique PTFE diaphragm.

Available in PVC, CPVC, Kynar PVDF, Natural Polypropylene, PTFE, and glass-filled Polypropylene; sizes 1/4" to 3" NPT.

Ideal for corrosive and other chemical process, as well as deionized water, reverse osmosis water...any ultra-pure liquid.

Plast-O-Matic relief valves deliver higher flow at lower overpressures than other typical relief valves. Operation is smooth, sensitive and extremely accurate.
