  • Cracking pressure of 3 psi ensures quick response
  • Rated for 235 psi water pressure at 70 °F

True Union Ball Check Valve

The Hayward TC30100T is a true union ball check valve designed for inline installation in piping systems. Its polypropylene body and Viton seals handle a range of fluids where chemical compatibility is required. The valve operates with a cracking pressure of 3 psi and provides full flow when open. It is intended for vertical mounting orientation in industrial or commercial plumbing applications.

Replaces Flanged or Threaded Non-Union Valves

This valve upgrades installations where valve removal previously required pipe disassembly or cutting. The true union ends allow the valve body to be removed for inspection or seal replacement while the pipe connections remain in place. The jump is worth it when maintenance access is limited or when system downtime must be minimised during service intervals. The 18 gpm flow capacity supports moderate demand lines.

Verify Connection Type and Pressure Limits

Confirm the existing piping uses 1 inch FNPT female threads to match the valve connections. Check that the maximum operating pressure does not exceed 235 psi at 70 degrees F and that fluid temperatures stay between 40 and 250 degrees F. Ensure the installation point allows vertical orientation for proper ball seating. Steam service is not rated for this valve.

Questions about this item

What pipe size and connection type does the 1" true-union check valve require?

The valve fits 1-inch piping with FNPT x FNPT threaded ends.

How must the valve be oriented during installation, and what is the common mistake?

It must be mounted vertically; installing it horizontally prevents the ball from sealing properly.

When should the Viton seals be inspected or replaced?

Inspect seals if leakage appears or after prolonged exposure near the 250 °F temperature limit.
