Hayward SLC10050TU Y-Check Valve True Union Spring-Loaded 1/2 in

SKU CH-DYG1-E00BH

Spring-loaded Y-check valve with true-union FNPT ends for 1/2 in PVC piping, rated 150 psi at 70 °F and 40–140 °F operating range

  • True union ends simplify installation and maintenance
  • Spring-loaded Y-check design prevents backflow automatically
  • PVC body with FPM seals resists corrosion and chemicals
  • Handles 150 psi at 70 °F for reliable service
  • Mounts horizontally or vertically for flexible piping

1/2 in True Union Y-Check Valve

The Hayward SLC10050TU is a spring-loaded Y-check valve built for 1/2 in FNPT connections. Its PVC body and FPM seals handle water up to 150 psi at 70 Degrees F and temperatures between 40 and 140 Degrees F. The true union design allows easy removal for maintenance without cutting pipe.

Replaces inline swing or ball check valves

This unit replaces basic inline check valves where a lower cracking pressure range of 2.000 to 15.000 psi and a compact Y-pattern flow path are required. The spring-loaded mechanism ensures positive sealing in both horizontal and vertical mounting orientations. The jump is worth it when a serviceable true union connection and FPM chemical compatibility are specified.

Verify FNPT threads and pressure rating

Confirm the existing piping uses 1/2 in FNPT threads and that system pressure does not exceed 150 psi at 70 Degrees F. Ensure the media temperature stays within the 40 to 140 Degrees F range and that FPM seat and seal material is compatible with the fluid. Steam service is not rated for this valve.

Questions about this item

Will the 1/2 in FNPT threads on this Y-check valve mate with my existing PVC piping?

The valve has 1/2 in FNPT x FNPT connections designed for PVC pipe with matching male NPT threads.

Do I need to orient the spring-loaded Y mechanism a certain way during installation?

The valve accepts both horizontal and vertical mounting; install so flow direction matches the arrow on the body.

When should I replace the FPM seals and stainless-steel spring inside this valve?

Inspect seals and spring annually; replace if cracking pressure drifts outside the 2.000 to 15.000 psi range or if leakage appears.
