Industrial Flow Control

The Value Brand 316 stainless steel swing check valve uses an inline swing mechanism with FNPT connections to prevent reverse flow in piping systems. Its 316 stainless steel body and PTFE seal resist corrosion in water and steam service. The unit is rated for a maximum water pressure of 200 psi and a maximum steam pressure of 200 psi WSP. Operating temperatures range from -4 degrees F to 350 degrees F.

Pressure And Temperature Limits

The valve opens at a cracking pressure of .5 psi, which suits low-head gravity-fed or pump-assisted lines. Service above 200 psi or 350 degrees F exceeds the rated limits and risks seal failure or body deformation. The PTFE seal material defines the upper temperature boundary for chemical compatibility. Horizontal mounting orientation is required for the swing disc to seat correctly under gravity.

Installation Notes

The 3 inch FNPT threads connect directly to matching female fittings without flanges or unions. Pipe dope or PTFE tape must be applied to male threads to ensure a leak-free seal at 200 psi. Installing the valve vertically or upside down prevents the swing disc from closing and defeats the check function. Debris in the line can jam the disc open, so upstream filtration is advisable.

Questions about this item

Should I choose a different cracking pressure or connection type for my 3" FNPT line?

This valve is built with a fixed .5 psi cracking pressure and 3" FNPT x FNPT connections; no alternative versions are offered for this model.

What does the 200 psi rating mean when the valve is installed in my piping system?

The 200 psi rating is the maximum allowable water and steam pressure the 316 stainless steel body and PTFE seal can handle continuously at up to 350°F.

Does the FNPT threaded connection limit the pressure or temperature I can run?

The FNPT threads are part of the same 316 stainless body rated for 200 psi and 350°F, so the connection does not impose a lower cap than the valve itself.
