Safety Relief Valve for Low-Pressure Steam
The Apollo 13101 valve protects low-pressure steam heating and supply boilers. It features a cast bronze body with EPDM disc and seat materials. The stainless steel spring and test lever ensure reliable operation. This new valve suits residential and light commercial hydronic systems requiring pressure relief.
Straightforward Threaded Installation
The unit connects via 3/4 inch MNPT inlet and FNPT outlet threads. Standard pipe sealant on male threads creates a leak-free joint. Over-tightening can crack the bronze body or strip threads. Verify the factory set pressure of 5 psi matches the boiler nameplate before fitting.
Fixed 5 psi Setting Within 5 to 15 psi Range
The valve opens at the factory-set 5 psi and cannot be field-adjusted. It handles steam capacity up to 333 lb/hr within a temperature range of 0 to 250 degrees F. Systems needing a different relief pressure or higher capacity require a separate valve model.
