CASH ACME 22348‑0150 — 3/4" NCLX‑A TEMPERATURE & PRESSURE RELIEF VALVE (150 PSI)

The Cash Acme 22348‑0150 NCLX‑A is a 3/4‑inch temperature and pressure relief valve engineered for residential and commercial water‑heater safety. Designed to provide automatic protection against excessive temperature and pressure, this valve is factory‑set to relieve at 150 PSI and 210°F, preventing tank rupture and maintaining system safety.

Constructed with a cast bronze body, brass and stainless‑steel internal components, and a silicone seat disc, the NCLX‑A offers corrosion resistance and long service life. An inert thermal element coating helps isolate the sensing element from mineral buildup, improving accuracy and reliability in hard‑water conditions.

This valve features a male NPT inlet × female NPT outlet, complete with a top-mounted test lever for manual testing and maintenance. The automatic reseating function ensures continued operation after temperature or pressure release, making it ideal for domestic water heaters, storage tanks, and thermal expansion protection.

The 22348‑0150 model includes a 3‑5/16" extended shank, suitable for thicker tank insulation or installations requiring additional reach.
