  • Factory-set 10 psi protects low-pressure steam boilers
  • Cast bronze body with EPDM disc resists 250 °F steam service
  • Stainless steel spring maintains consistent relief across 5 to 15 psi range
  • 509 lb/hr steam capacity handles heating system demand
  • CRN-registered design meets Canadian pressure-vessel requirements

Safety relief valve for low-pressure steam boilers

This Apollo 13202B10 valve protects low-pressure steam heating and supply boilers with a factory-set pressure of 10 psi. The bronze body and EPDM disc handle steam capacities up to 509 lb/hr within a 5 to 15 psi adjustable range. It suits installations requiring a 1-inch MNPT inlet and 1-inch FNPT outlet.

Sustained steam discharge at rated capacity

Under continuous steam flow the valve maintains its set pressure without short-cycle bursts. The stainless steel spring and EPDM seat materials are rated for temperatures up to 250 degrees F, providing consistent blow-off performance during prolonged heating cycles. The included test lever allows periodic verification without removing the valve from service.

Bronze construction with threaded connections

Cast bronze body resists corrosion in steam environments while the MNPT inlet and FNPT outlet fit standard 1-inch piping. Overall height of 2 1/16 inches and length of 5 3/8 inches allow installation in confined boiler rooms. Not suited for hot-water hydronic systems, compressed air lines, or applications requiring pressures above 15 psi.

Questions about this item

Does the Apollo 13202B10 valve generate noise or heat when relieving steam continuously at 10 psi?

The valve operates silently until it opens at the 10 psi set point, then discharges steam at up to 509 lb/hr; the cast-bronze body and EPDM seat handle the 0 °F to 250 °F range without overheating.

What piping and fittings must I already have to install this 1-inch MNPT inlet and FNPT outlet valve?

You need 1-inch NPT pipe threads on both supply and discharge sides, plus thread sealant or tape rated for steam service up to 250 °F.

Will this 10 psi relief valve protect an older cast-iron boiler rated for 15 psi maximum working pressure?

Yes, the factory-set 10 psi opening pressure and 5 psi to 15 psi adjustable range keep it well below the boiler’s 15 psi limit, and the CRN certification covers low-pressure steam heating boilers.
