Dayton 4RG92 1-1/2 in PVC Ball Check Valve

SKU CH-JYQG-QPJZ4 MPN 4RG92

Inline ball check valve prevents back-flow in 1-1/2 inch PVC socket connections

  • TypeDrain Components
  • Inline ball mechanism prevents backflow
  • PVC body resists corrosion in drainage systems
  • 1-1/2 in socket connections fit standard pipe
  • Vertical mounting orientation simplifies installation
  • General-purpose design suits multiple drain applications

Application & Orientation

This Dayton 4RG92 valve suits general-purpose drainage where back-flow prevention is required. It installs vertically with a socket-by-socket connection on 1-1/2 inch PVC pipe. The inline ball mechanism opens under forward flow and seats automatically when flow stops or reverses. It is not rated for steam service.

Fit & Limitations

Builders working on vertical drain lines in residential or light-commercial plumbing will find this valve a direct fit. Horizontal or angled mounting orientations are not supported by the design. Systems that demand a steam-rated component or a different connection type such as threaded or flanged ends should select another valve.

Deciding Specification

The single specification that determines suitability is the vertical mounting orientation combined with a socket-by-socket connection for 1-1/2 inch PVC pipe. If the installation cannot meet both requirements the valve will not function as intended.

Questions about this item

What comes in the box with the Dayton 4RG92 and do I need extra fittings?

The box contains the valve body only; you must supply solvent cement and any pipe lengths required for your 1-1/2 in socket connections.

How do I choose the right version of this check valve?

This model is a single inline ball design in PVC with 1-1/2 in socket ends and vertical mounting — select it when those exact specifications match your system.

What does the 1-1/2 in socket size mean once the valve is installed?

It fits directly onto 1-1/2 in PVC pipe with solvent-weld sockets, giving a straight-through flow path that opens under forward pressure and closes automatically when flow stops.
