SKU CH-T9PB-EXRDE

A 1-inch PVC Y-check valve with FPM seals, rated to 150 psi at 70 degrees F and operating from 40 to 140 degrees F

  • Reliable back-flow prevention with Y-pattern single-check design
  • Leak-resistant FPM seals handle 40–140 °F fluid temperatures
  • Threaded FNPT ends install directly in 1" PVC piping
  • Rated for 150 psi at 70 °F working pressure
  • Full 9 gpm flow capacity with 1 psi cracking pressure

Product Identity

The Hayward YC10100T is a Y-pattern check valve designed for fluid-control systems. It suits installers who need a compact, non-return valve for horizontal or vertical pipe runs. Builders working with aggressive media at moderate pressure will find the PVC body and FPM seals compatible with their specifications.

Critical Specification

The valve carries a maximum water-pressure rating of 150 psi at 70 Degrees F. This single figure determines whether the component matches the system design pressure. Exceeding this limit risks seal failure or body deformation, so verify the operating pressure before selection.

Thermal and Operational Limits

Continuous service temperatures must stay between 40 and 140 Degrees F. Within this range the FPM seat maintains sealing integrity without softening or hardening. The 1 psi cracking pressure ensures minimal head loss during normal flow while preventing backflow when the pump stops.

Questions about this item

What flow rate does the 9 gpm rating deliver in a live system?

The valve passes up to 9 gallons per minute when fully open, with a 1 psi cracking pressure that lets flow start almost immediately.

How does the FNPT threaded connection limit pressure and temperature?

The 1-inch FNPT threads seal at 150 psi maximum at 70 °F and handle continuous water temperatures from 40 °F to 140 °F.

What clearance and orientation does the Y-body need for installation?

The Y-pattern body fits in horizontal or vertical pipe runs and requires enough straight pipe to accommodate the 1-inch threaded ends.
