Zoro Select 2 in Brass Swing Check Valve

The Zoro Select swing check valve uses a 2 in FNPT threaded brass body to prevent back-flow in horizontal water or steam lines. An inline swing mechanism opens under forward pressure and closes by gravity when flow stops. Rated for 200 psi water pressure at 73 °F and 120 psi steam pressure, it suits residential and light-commercial plumbing installations.

Installers needing a simple non-return valve

This valve fits horizontal piping only and cannot be used in vertical orientations. The brass seat and seal limit chemical compatibility, so it is not for aggressive fluids or potable-water systems requiring lead-free certification. Buyers who need a spring-loaded or silent-closing design should look at alternative check-valve types.

Cracking pressure of .725 psi

The valve begins to open at a low .725 psi differential, allowing flow to start with minimal head pressure. This single figure determines whether the valve will operate reliably in low-pressure gravity-fed systems or whether a higher-cracking-pressure model is required.

Questions about this item

What comes in the box with the ZORO SELECT 2 in swing check valve and do I need to buy pipe sealant or fittings separately?

The valve ships as a single brass unit with FNPT threads on both ends. Pipe sealant, tape, and any mating fittings are not included and must be sourced separately.

Should I choose this 2 in FNPT brass valve or a different size for a 120 gpm water line rated at 200 psi?

This model matches a 2 in line, handles 120 gpm flow, and is rated 200 psi at 73 °F water pressure. Select a different size only if your pipe diameter differs.

What does the 0.725 psi cracking pressure mean when the valve is installed horizontally in a 212 °F hot-water system?

The disc begins to open at 0.725 psi differential, allowing flow in the forward direction. It operates up to 212 °F and 200 psi water pressure in horizontal mounting.
