FilterChem™ Pressure By-Pass Valves

These three-port adjustable combination valves can be used for by-pass and pressure relief applications. They bypass excess fluid or air whenever the pressure set with the handle is exceeded and permit straight-through flow if mounted in a straight line. In other applications, the valve can be mounted on the branch end of a tee by plugging one side hole and piping to the side of the valve. Note: Product testing for individual applications is recommended before use. U.S. Plastic Corp. cannot be held liable for individual application failures. EPDM or Kalrez O-rings are available by special order; contact us for a quote.
