Pressure-Rated Bronze Relief Valve

This Apollo 1060410 safety relief valve protects heating equipment by releasing excess pressure at a factory-set 50 psi. The bronze body with brass disc and silicone seat handles hot water up to 250 °F. Inlet and outlet are both 3/4-inch FNPT, and the overall height is 5 5/8 inches. A test lever is included for manual verification.

Heating Systems Requiring 50 PSI Protection

Installers fitting residential or light-commercial hydronic boilers, water heaters or storage tanks that demand a 50 psig relief setting will find this valve a direct match. The pressure range spans 15 to 160 psi, but the spring is factory locked at 50 psi and is not field-adjustable. Systems needing a different set pressure or a larger flow capacity should select another model.

Factory-Set 50 PSI Relief Pressure

The single specification that decides fitment is the non-adjustable 50 psig factory setting stamped on the nameplate. If the engineering drawings or local code call for any other relief pressure, this valve cannot be used. Confirm the required set pressure before ordering.

Questions about this item

Does the Apollo 1060410 valve generate noise or heat during continuous operation?

The valve operates passively with no moving parts that generate noise or heat; it opens only when system pressure exceeds the 50 psig factory setting and closes once pressure drops.

What piping and fittings must already be in place to install this 3/4 inch FNPT valve?

You need 3/4 inch FNPT threaded connections on both the inlet and outlet sides, plus pipe thread sealant or tape suitable for bronze and brass components.

Will the 15 to 160 psi adjustable range work with an older boiler rated below 50 psi?

The valve is factory set at 50 psig; if the older boiler operates below that pressure the valve will remain closed, so verify the system design pressure before installing.
