CASH ACME 23577‑0150 — 3/4" NCLX‑5LX TEMPERATURE & PRESSURE RELIEF VALVE (150 PSI)

The Cash Acme 23577‑0150 is a 3/4‑inch NCLX‑5LX temperature and pressure relief valve engineered to protect residential and commercial water heaters and storage tanks from excessive temperature or pressure buildup. Designed for high‑performance safety applications, this model is factory‑set to relieve at 150 PSI and 210°F, ensuring dependable protection against tank over‑pressurization and overheating.

Built with a cast bronze body, brass and stainless‑steel internal parts, a silicone seat disc, and a stainless‑steel spring, the NCLX‑5LX offers long‑term corrosion resistance and durability, even in demanding water conditions. The valve incorporates an inert thermal element coating, preventing mineral accumulation on the sensing element and maintaining reliable operation.

This model features a 3/4" MNPT inlet × 3/4" FNPT outlet, along with an extended shank length commonly used on deeper tank jackets or insulated water‑heater designs. A top‑mounted test lever allows for routine operational testing, and the valve automatically reseats after either temperature or pressure relief.

Rated for up to 500,000 BTU/hr (varies by configuration), the NCLX‑5LX is approved for use on residential heaters, commercial storage tanks, and closed‑loop systems requiring certified T&P protection.
