PS/UL Pressure Relief Valve

 Pressure Relief Valve (UL)

Hydraulic pressure relief valve
The valve maintains a steady preset upstream pressure. Should
the upstream pressure exceed the required set point, the valve
opens, releasing excessive pressure. When the pressure falls
below the preset level, the valve closes drip tight.

Pressure rating, adjustment range & features:
• UL listed pressure rating/maximum pressure (psi)
Class 150 (ISO PN16) - 250 psi max.
Class 300 (ISO PN25) - 375 psi max
• UL listed maximum relief pressure (psi):
Class 150 (ISO PN16) - 175 psi & 205 psi
Class 300 (ISO PN25) - 375 psi
• Reliable pressure control from near zero flow to full flow with no need for additional throttling plug or by-pass valves
• Exhibits the same low pressure losses as in the basic valve
• Simple structure

Applicable for:
• Water, Sea water and Foam
