1/2-Inch Pressure Reducing Valve

The Apollo 36ELF11301S is a lead-free bronze valve designed to reduce incoming water pressure to a safer level for residential plumbing systems. It suits homeowners and plumbers who need reliable pressure control on a 1/2-inch supply line. The single union solder-by-NPT connection simplifies installation on copper piping. This valve meets NSF/ANSI 61 and low-lead compliance standards for potable water use.

Adjustable Range and Working Limits

The valve provides an adjustable outlet range of 15 to 75 psi and is factory set at 50 psi for typical household demand. Maximum working pressure reaches 400 psi, while the maximum operating temperature is 180 degrees Fahrenheit. These ratings support normal daily flow without excessive noise or stress on downstream fixtures. Certified to ASSE 1003 and CSA B356, it delivers consistent regulation under standard service conditions.

Sustained Load Behaviour

Under continuous demand the bronze body and certified internals maintain the set pressure without drift, protecting appliances and piping from pressure spikes. The 6-inch height and 4-1/2-inch length fit within typical service clearances for long-term access. Compliance with California AB1953 and Vermont Act 193 ensures ongoing suitability for potable water installations. The valve is restricted from sale in certain states due to Proposition 65 chemical content.

Questions about this item

How do I install the 1/2 inch single union solder by NPT connection without leaks?

Solder the union tailpiece to the copper supply line before threading it onto the valve body to avoid overheating the internal cartridge.

Which internal part will need replacement after years of pressure cycling?

The lead free bronze cartridge and seat assembly wear over time and are the components typically swapped during rebuilding.

At what inlet pressure does the 400 psi maximum working limit become a concern?

The 400 psi rating is the structural ceiling; sustained supply pressure above that level risks body deformation even if the adjustable range stays at 15 to 75 psi.
