Safety Valve Series

Jacketed Safety Relief Valve

Steam-jacketed body prevents medium solidification.

As part of the VTXFLOW safety valve range, the jacketed safety relief valve is produced under our certified quality system — from in-house casting and CNC precision machining to 100% pressure and seat-tightness testing before shipment. Our safety and safety-relief valves protect vessels, boilers and piping from overpressure. Spring-loaded and pilot-operated designs are set, tested and sealed in-house on certified test benches.

  • Every valve set and seat-tightness tested to API 527
  • Blowdown adjustable via control rings
  • Bellows option isolates spring from back-pressure
  • Lifting lever options for boiler code compliance
