Apollo 36LF40301 Pressure Reducing Valve

The Apollo 36LF40301 is a lead-free bronze pressure reducing valve built for residential water systems. It fits 1/2 inch NPT double-union connections and adjusts outlet pressure between 25 and 75 psi with a factory setting of 50 psi. The valve meets ASSE 1003 and CSA B356 standards as well as CA AB1953 and VT ACT 193 low-lead requirements. It is intended for installers who need code-compliant pressure control on potable water lines.

Thermals Noise Power Draw

The valve body is rated for a maximum working pressure of 300 psi and a maximum water temperature of 180 degrees Fahrenheit. As a purely mechanical device it produces no electrical noise and draws no power during operation. Pressure is regulated by an internal spring and diaphragm assembly that responds to downstream demand without external energy input.

1/2 Inch Double Union NPT Connection

The 1/2 inch double-union NPT ends determine whether this valve fits the existing piping. Installers must verify that the supply and distribution lines use matching 1/2 inch NPT threads before purchase. The union design allows the valve body to be removed for service without cutting pipe, but the thread size and type are fixed and cannot be adapted to other connection standards.

Questions about this item

How do I install the Apollo 36LF40301 valve and which step is often missed?

Thread the 1/2 In. double union NPT connections onto the supply lines, then tighten the union nuts. The step often missed is orienting the valve so the adjustment bolt is accessible for future pressure changes.

What maintenance or replacement will the 36LF40301 need later?

Inspect the internal strainer screen annually for debris and clean it. Replace the diaphragm and seat assembly if outlet pressure drifts outside the 25-75 psi range or if leakage appears at the union joints.

What limit appears first on the 36LF40301 during sustained high-demand use?

The 180 F maximum temperature rating is the first limit reached under sustained hot-water demand, restricting use in systems that exceed this temperature.
