Apollo 1/2 Inch Pressure Reducing Valve

The Apollo 36ELF12301T is a lead-free bronze water pressure reducing valve built for residential and light commercial plumbing. It fits 1/2 inch NPT double-union connections and adjusts from 15 to 75 psi with a factory setting of 50 psi. Installers use it to protect fixtures and appliances from excessive supply pressure.

Thermals Noise And Power In Normal Use

The valve operates passively with no electrical power, so it adds no noise or heat to the system. It handles water temperatures up to 180 F and a maximum working pressure of 400 psi. The adjustable range lets you set downstream pressure to match local code or equipment requirements.

Build Quality And Daily Implications

The lead-free bronze body meets NSF/ANSI 61, CA AB1953 and VT Act 193 for potable water safety. Double-union NPT ends allow the valve body to be removed for cleaning or cartridge replacement without cutting pipe. ASSE 1003 and CSA B356 certification confirms compliance with recognized performance standards.

Questions about this item

How do I install the Apollo 36ELF12301T pressure reducing valve and what step is commonly missed?

Thread the 1/2 in. double union NPT connections onto the supply lines using lead free bronze compatible sealant, then tighten both union nuts evenly; the step often missed is confirming the factory pressure setting of 50 psi before closing the system.

What maintenance or replacement will the Apollo 36ELF12301T valve need over time?

Inspect the lead free bronze body and internal cartridge annually for mineral buildup; replace the cartridge if outlet pressure drifts outside the 15 to 75 psi adjustable range or if leakage appears at the union seals.

What limit appears first on the Apollo 36ELF12301T during sustained high demand flow?

The 400 psi maximum working pressure rating is the first hard limit; sustained inlet pressure above that value can damage the bronze body even though the adjustable outlet range stops at 75 psi.
