Brass swing check valve for plumbing systems

This 1-1/4 inch NPT brass swing check valve prevents back-flow in water and steam lines. The inline swing mechanism opens with flow and closes automatically when pressure drops. Brass body and seat resist corrosion in residential and light-commercial piping. Suitable for horizontal mounting only.

Cracking pressure of 0.725 psi

The valve begins to open at a very low 0.725 psi cracking pressure, allowing flow to start with minimal head loss. This specific figure determines whether the valve will operate correctly in gravity-fed or low-pressure circuits. Systems requiring a higher opening pressure will need a different valve design.

Operating range 32 to 212 degrees Fahrenheit

The valve handles water up to 200 psi at 73 degrees Fahrenheit and steam up to 120 psi. Brass construction withstands the full temperature span from freezing to boiling water. Flow capacity reaches 46 gpm in the fully open position. California Proposition 65 warnings apply for chemical exposure.

Questions about this item

What does the 46 gpm flow rating mean when the valve is installed in a plumbing system?

It indicates the maximum water volume the valve can pass when fully open under typical conditions, so size your pump and piping to stay at or below that rate.

How does the FNPT x FNPT connection affect the pressure the valve can handle?

The female NPT threads mate with standard male NPT fittings, and the assembly is rated for 200 psi water pressure at 73 °F and 120 psi steam pressure.

What clearance and orientation are needed to mount this 1-1/4 inch brass swing check valve?

It must be installed horizontally, so allow enough straight pipe run for the swing disc to open freely without contacting adjacent fittings or walls.
