Pressure Relief Valve (Safety Valve)

PME Pressure Relief Valves (Spring-loaded or Pin-type) provide essential overpressure protection for high-pressure pumps and manifolds. Engineered to automatically release pressure at a pre-set value, these safety valves prevent catastrophic equipment failure and ensure personnel safety on the drilling site.

  • Relief Pressure: Customizable up to 15,000 PSI (105 MPa).
  • Connection: Standard FIG 1502 Hammer Union or Flanged Ends.
  • Feature: Rapid response, accurate resetting, and corrosion-resistant internals.

Critical Features & Safety Benefits

Instant Response

Designed for rapid opening when internal pressure exceeds the safety limit, ensuring immediate protection for fracturing and cementing lines.

Accurate Resetting

Features high-quality spring and seal mechanisms that allow the valve to reseat precisely once pressure returns to safe levels, minimizing fluid loss.

Forged Durability

Manufactured from high-strength forged alloy steel to withstand extreme vibration and pressure surges common in oilfield services.
