Pressure Reducing and Pressure Relief Valves

PR\UL - PRESSURE REDUCING VALVE

Pressure Reducing Valve

  • Model 30U-PR\UL

An Automatic, Pilot-controlled, Pressure-Reducing valve, actuated by the pipeline pressure. The valve regulates to a steady, preset downstream pressure, regardless of upstream pressure or flow rate fluctuations. In case of excessive downstream pressure, the valve closes drip-tight.

Pressure rating, adjustment range & features:

  • UL Listed pressure rating up to 375 psi / PN25
  • UL listed downstream Pressure adjustment range 30-165 psi
  • Other certified (non UL) downstream pressure setting range:
    • 2” - 8”: 30 – 360 psi
    • 10” – 12”: 30 – 285 psi

Features:

  • UL Listed
  • Superior design featuring low pressure losses at high flow rates
  • Stable regulation from near zero flow to maximum design flow
  • The PR\UL valve regulates at low flow and high pressure differential without bypass or U port design
  • Low lifelong maintenance costs thanks to its unique design
  • Standard Stainless Steel seat
  • Simple field adjustable pressure setting with no special tools or system down time
  • Fresh or brackish water, seawater and foam systems
  • Out-of-the-box fully assembled & tested valves
  • All valve control ports are stainless steel sleeved CF8M or higher for improved corrosion protection


Applicable for:

Water, Sea water and Foam

PS\UL - PRESSURE RELIEF VALVE

Pressure Relief Valve

  • Model 30-PS\UL
  • Model 77-PS\UL
  • Model 44-PS\UL

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.

 

Pressure rating, adjustment range & features:

  • UL listed pressure rating up to 375 psi / PN25
  • UL listed maximum relief pressure up to 375 psi

Features:

  • UL Listed
  • Superior design featuring low pressure losses at high flow rates
  • Low lifelong maintenance costs thanks to its unique design
  • Simple field adjustable pressure setting with no special tools or system down time
  • Fresh or brackish water, seawater and foam systems
  • Out-of-the-box fully assembled & tested valves

Applicable for:

  • Water, Sea water and Foam
