Self-Acting Pressure Reducing Valve -- Pilot Steam WCB

Self-acting pilot-operated pressure reducing valves in WCB carbon steel for steam pressure reduction stations, process steam distribution, and hot water system pressure control. The pilot-operated design provides high accuracy and high turndown ratio without external power, electricity, or compressed air. Multi-stage piston/disc assembly with SS316+Stellite trim ensures long life in steam cutting conditions. External sensing line and easy set-point adjustment simplify commissioning and maintenance.
