Spirax-Sarco 54663 Main Valve Freon Does it require a specificThe Spirax Sarco 54663 is a 4 inch ANSI 125 flanged main valve engineered for precision in high capacity steam distribution systems. As a core component of the 25 Series, this pilot operated pressure reducing valve (PRV) utilizes a self actuated design, leveraging downstream pressure feedback via an external sensing line to modulate flow. This cast iron unit is built for heavy duty service, featuring stainless steel internals and a fatigue tested
