PVC RELIEF VALVES/REGULATORSPRESSURE RELIEF VALVES300.130.110 AllPRESSURE REGULATORS300.130.120 AllFEATURES• Protect against accidental excessive pressure.• Free from both internal and external corrosion.• No tools are required to set the relief pressure.• This PVC valve is similar in design and function to metal reliefvalves, except that no metal touches the fluid.• The valve can be preset to open at any desired pressurebetween 5 and 75 PSI, and you have your choice of Viton orEPDM seals. If the line pressure does not reach the set reliefpressure, the valve remains closed. When pressure exceedsthe relief value, the valve opens and diverts the flow. Thesetting is maintained by a PVDF-coated steel spring that iscompletely isolated from the system. Once preset, the valvewill continue to function continuously.• A threaded port is integrally molded into body for ease ofmounting an optional pressure gauge to check the system.ORDER: 5464.(Size No.) PRESSURE RELIEF VALVE, PVCThreadedSizeNo. Nom.

Conversely, if the flow is reducedbecause of a system pressure drop, the regulator will openwider to allow more flow. It works continuously to insure thatthe downstream pressure never exceeds the set pressure ofthe regulator.• The regulator can be easily set to control any desired systempressure between 5 and 75 PSI. This can be done by handwithout use of tools.• The body of the piece is molded of PVC—the only metalcomponent (a PVDF-coated spring) is completely isolatedfrom the flow system. The unique, one-piece molded bodyincorporates a 1/4” NPT port for connecting an optionalpressure gauge.ORDER: 5467.(Size No.) PRESSURE REGULATOR, PVC,Threaded, VitonSizePriceNo. Nom. Pipe Size (in.)
