POPRV – Series 500

SERIES 500 MODULATING SAFETY RELIEF VALVE

The Series 500 is a modulating, soft-seated pilot operated valve offering premium tightness with the ability to handle temperatures from -65°F to 515°F (-54°C to 268°C). It is designed to decrease leakage associated with metal-seated safety relief valves under extreme operating temperature conditions. The soft seat in its main valve is more resistant to particulate damage than a metal seat, has a longer service life and can be replaced quickly while the valve body remains installed in the line. Additionally, its unique design enables the main valve to be tight at pressures up to set point. After relieving and reseating, it stays bubble-tight, cycle after cycle

GENERAL APPLICATION

Applications for the Series 500 include hot water, steam (ASME Section VIII and XIII Unfired Pressure Vessels), hot hydrocarbon vapors or liquids and corrosive services

FEATURES

  • Increased system output with total valve tightness to 95% of set pressure without leakage.
  • All plastic seats and seals provide chemical compatibility with the lading fluid.
  • Balanced design ensures proper valve operation and lift unaffected by back pressure, eliminating the need for costly and fragile metal bellows.
  • Unique field test capability allows accurate set pressure verification with valve in service. No system isolation block valve required.
  • Resilient seats greatly extend service life and reduce maintenance cost, eliminating expensive metal seat lapping.
  • Reduced product loss and pollution through soft seats for premium tightness before and after relief cycles.
  • Modulating action minimizes flow and resultant noise during normal system upset, reducing noise abatement costs.
  • Easy, single set pressure adjustment is accurate and dependable.
  • ASME Section VIII and Section XIII (UV Designator) Code Stamp for steam, gas and liquid service and CE mark to European PED 2014/68/EU.
