3" Regulator Press Air Pilot Threaded PVC EPDM 5-125 psi
Item #PRA300EP-PV
  • Handles inlet pressure up to 150 psi, downstream settings from 5-125 psi
  • Ideal for applications requiring frequent adjustments or remote control
  • Materials of construction: PVC, natural polypropylene, PVDF
  • Rolling diaphragms provide exceptional sensitivity
  • Million cycle design
  • Threaded ports standard; socket, flanged and spigot connections optional
  • One-piece body and double U-cup design prevent leakage and eliminate creep
  • For critical ultrapure and corrosive liquid applications Caution: Quick shutoffs of downstream equipment or valves transmit liquid shock waves back to the regulator with the possibility of damaging it. Gradually close valves or equipment to avoid these shocks. If a valve must be closed quickly, it is best to do so upstream of the regulator.

Designed for highly corrosive and ultra-pure chemicals, this pressure regulator uses compressed air to control pressure with greater accuracy as compared to standard spring controlled models. Sizes 1/4", 1/2" and 3" are series PRA; sizes 3/4", 1", 1 1/2", and 2" are series PRAM. The PRA.PRAM will routinely handles inlet pressure up ro 150 PSI and accurately maintain a downstream pressure from 5 to 125 PSI. The design features two large are frictionless rolling diaphragms. Process pressure is applied to one of the diaphragms; air pressure is applied to the other. Because the air pressure can be maintained with more accuracy than the force provided by the spring, the PRA/PRAM offers greater sensitivity and less vairance from set pressure than any thermoplastic pressure regulator previously available.
