  • Spring-loaded 316 stainless steel ensures reliable closure at .5 psi cracking pressure

  • Operates horizontally or vertically from 35 °F to 120 °F
  • 2 in slip x slip connections install quickly without threading

Purpose and Fit

The MAGIC B-0823-20 is a two-inch inline silent check valve built for PVC plumbing systems. It uses a slip-by-slip connection so it joins pipe directly without threads. The valve opens at a cracking pressure of .5 psi and handles water pressure up to 150 psi at 72 degrees F.

Who It Suits and Who Should Look Elsewhere

This valve suits installers who need quiet back-flow prevention in horizontal or vertical runs carrying water between 35 and 120 degrees F. It is not rated for steam service, so systems carrying steam or exceeding the temperature limits require a different valve design.

Build Integration

The PVC body and Buna-N seal resist corrosion in standard water lines while the 316 stainless steel spring maintains reliable closure. Slip connections let the valve slide into existing two-inch PVC pipe, reducing the need for extra fittings. The four-inch overall length keeps the installed footprint compact.

Questions about this item

What size PVC pipe and fittings do I need for the 2 in slip connections on this check valve?

The valve uses 2 in slip-by-slip connections, so it fits directly into standard 2 in PVC pipe and slip fittings without threading.

Can I install this inline silent check valve vertically in an existing horizontal PVC line without changing the spring?

Yes, the valve is rated for both horizontal and vertical mounting orientations with the same 0.5 psi cracking pressure.

How can I confirm the 316 stainless steel spring is seating properly after installation?

Run water through the line; the valve should open at 0.5 psi and close silently with no visible backflow when the pump stops.
