Pressure Relief Valve


Application

Pressure relief valves are Compatible with all CFC, HCFC and HFC Refrigerants and oils and other Industrial gases and fluids non-corrosive to steel and brass. (With suitable Gland/Seal).

Construction

  • Valve Body: Extruded Brass.
  • Valve Cap : Forged Brass
  • Spring: Stainless Steel
  • Seat Material: Neoprene/Teflon.
  • Machined parts: Extruded Brass.

Design

  • Pre compressed special grade SS Spring provides unchanged tension for life of Valve.
  • Pre stressed virgin seat material improves accuracy of pressure ratings.
  • Designed for quick Discharge and immediate shut down.
  • Available in pressure Range from 150psig – 450 psig.
  • Pre set on imported accurate pressure gauge.
  • Working Temperature range is -30°C to 100°C.

Installation.

  • Inspect valve and Install only if factory seal appears untampered.
  • For leak tight sealing use Torque wrenches set at 30 Lb.Ft and ensure that Female thread is exact match.
  • Shelf life of Valve is 18 months from date of manufacture. Beyond this period if unused return valve to Factory for recalibration.
  • We recommend replacement of the valve after it pops open. It may not open again at preset pressure on account of Debris impregnation in seat and ageing of seat material.
  • Under no circumstances open the seal and try to reset the valve as it needs special tools and trained technicians.
