Pressure Relief Valve

An automatic, pilot controlled, pressure relief valve, actuated by the pipeline pressure. The valve modulates to maintain a steady, predetermined pressure in the network. Should the upstream pressure exceed the required set point, the valve opens, releasing the excessive pressure. When the pressure falls below the set value, the valve closes drip tight.



  • Simple field adjustable pressure setting; no special tools or system downtime
  • Superior design featuring low pressure losses at high flow rates
  • Low lifelong maintenance costs due to unique frictionless internal trim design
  • High flows and working pressures (PN25/375psi)
  • Maintains a steady preset system pressure, regardless of fluctuating supply
  • Protects the system by accurately limiting maximum pressure
  • Out of the box fully assembled & tested valves
  • Extensive valve and trim materials selection and corrosion protection coating
  • Stainless Steel seat as standard
