The NCLX T&P Relief Valve incorporates an inert thermal element coating that provides effective isolation from mineral deposits (liming) and galvanic corrosion. The NCLX features include a cast bronze body, brass and stainless steel internal parts, silicone seat disc and stainless steel spring. The NCLX comes standard with a test lever. The valve is completely automatic and reseats after either temperature or pressure relief. The NCLX is available in male inlets and female outlets with several options in shank and element lengths. Every valve is tested for performance prior to shipping to specify and install with confidence!
