White PVC Y-check valve with socket ends, 3 inch size

Hayward Flow Control

Hayward Flow Control YC10300SE 3 in PVC/EPDM Y-check valve Socket

SKU CH-7QK4-4G2QC

A 3-inch PVC/EPDM Y-check valve with socket connections, rated for 150 psi at 70°F and 110 gpm flow

  • Reliable backflow prevention with Y-pattern check design
  • Durable PVC body with EPDM seals for chemical resistance
  • Simple socket connections for solvent-weld installation
  • Handles 110 gpm flow at 150 psi pressure rating
  • Operates from 40 to 140 degrees Fahrenheit

Product Identity

The Hayward Flow Control YC10300SE is a three-inch Y-pattern check valve built from PVC with EPDM seals. It uses a single-disc flow design that opens at one psi and handles up to 150 psi water pressure at 70 degrees F.

Fit and Alternatives

This valve suits horizontal or vertical plumbing runs that need full 110 gpm flow without a steam rating. It is not for systems that operate above 140 degrees F or below 40 degrees F, or for any installation that requires a steam-rated component.

Deciding Specification

The socket-by-socket connection means the valve is solvent-welded directly into the pipework, so the installer must be prepared to make permanent joints rather than threaded or flanged connections.

Highlights

  • Reliable backflow prevention with Y-pattern check design
  • Durable PVC body with EPDM seals for chemical resistance
  • Simple socket connections for solvent-weld installation
  • Handles 110 gpm flow at 150 psi pressure rating
  • Operates from 40 to 140 degrees Fahrenheit

Questions about this item

How do I install the 3-inch socket Y-check valve and which orientation step is often missed?

Solvent-weld each socket to 3-inch PVC pipe using primer and cement; the valve accepts horizontal or vertical mounting but the Y-pattern body must slope downward so gravity can close the disc — installing it level is the common error.

What maintenance will the EPDM seat and seal need over time?

Inspect the EPDM seat annually for hardening or tears caused by chlorine or ozone exposure; replace the seat if leakage appears at the 1 psi cracking pressure, using only EPDM-compatible lubricant during reassembly.

At what pressure limit does the valve reach its rating during sustained 70 °F water flow?

The maximum working pressure is 150 psi at 70 °F; sustained operation above this pressure or above 140 °F water temperature will exceed the PVC body rating.
