Technical Data

  • Operating Pressure: 0 - 200 PSI
  • Cracking Pressure 0.5 - 150 PSI Higher cracking pressures available, please check with Amron sales representative.
  • Adjustment: ± 50% of nominal  Adjustment is on inlet side and cannot be tampered with after valve is installed.
  • Cracking Pressure Accuracy: Operating tolerance for cracking pressure is 5%. Initial crack may be slightly higher than cracking pressure tolerance.
  • Deflector Cap: Diverts high pressure blasts from personnel or instruments. Serves as a rain and dust shield. Increases flow capacity and facilitates manual override. The D500 Model with cap is available only in the discharge to atmosphere version of the valve.
  • Repair Kits: RK-D559B-4MP-10  Order by prefixing Part number with “RK” Give complete part number including size and cracking pressure.

Operating tolerance for cracking pressure is 5%. Initial crack may be slightly higher than the cracking pressure tolerance. Cracking pressure is defined as 5 cc/min. with gas.

Descriptions

Circle Seal Series 500 Relief Valves have a resilient seal design that prevents leakage. Sealing efficiency increases with increased pressure up to cracking pressure. When system pressure overcomes spring force, poppet opens. Seal provides zero leakage at reseat.
