1-1/2" Slip PVC Silent Check Valve

This 1-1/2 inch slip-by-slip check valve uses a clear PVC body with an inline silent mechanism. It is built for plumbing systems that need quiet, automatic back-flow prevention in horizontal or vertical runs. The Buna-N seal and 316 stainless steel spring handle water up to 150 psi at 72 degrees F.

Cracking Pressure .5 psi

The valve opens at a cracking pressure of .5 psi, making it the decisive spec for low-head gravity or pump-assisted lines. If the system cannot reliably exceed this pressure, the disc will not lift fully and flow will be restricted. Builders needing a higher or lower opening point must select a different valve.

Horizontal or Vertical Mounting

The design mounts in either orientation without modification, freeing the installer from re-piping for valve alignment. The clear PVC body allows visual confirmation of disc movement during commissioning. It is not rated for steam service and the minimum operating temperature is 35 degrees F.

The valve begins to open at .5 psi and is rated for a maximum water pressure of 150 psi at 72°F; it is not rated for steam service.

What pipe size and connection does the clear PVC body accept?

The body is built for 1-1/2 inch slip-by-slip solvent-weld connections on standard PVC pipe.
