1-1/2" NPT Stainless Steel Swing Check Valve

The Value Brand check valve uses a 316 stainless steel body with PTFE seals to handle water up to 200 psi and steam at 200 psi WSP. It operates between -4 and 350 degrees Fahrenheit with a low cracking pressure of .5 psi. The inline swing design provides full flow at 72 gpm for horizontal piping systems.

FNPT x FNPT inline connections

Female NPT threads on both ends allow direct installation into existing 1-1/2 inch pipe without extra adapters. The horizontal mounting orientation means the valve must be positioned level for the swing disc to open and close correctly. The 316 stainless construction resists corrosion in aggressive water or chemical environments.

PTFE seal and full-flow rating

The PTFE sealing material maintains integrity across the full temperature range without degrading. A full-flow rating of 72 gpm confirms the internal bore matches the pipe size, reducing pressure drop across the valve. No additional gaskets or actuators are included, so installers supply their own thread sealant and mounting hardware.

Questions about this item

What does the 0.5 psi cracking pressure mean for how the valve opens?

The valve begins to open at a very low differential of .5 psi, allowing flow to start with minimal upstream pressure.

What pipe size and thread type does this valve connect to?

It fits 1-1/2 inch piping with FNPT threads on both ends for a direct threaded connection.

How do I orient the valve during installation so it works correctly?

Install it horizontally with the flow arrow pointing in the direction of system flow; vertical mounting will prevent proper swing operation.
