Worcester Controls 1SR-44 Ball Valve Assembly

The Worcester Controls 1SR-44 Spring-Return Handle with Asahi 25-1 Valve is a quarter-turn ball valve assembly that delivers precise manual flow control with automatic spring-return positioning for fail-safe shutoff in industrial process piping. This spring-return manual actuator handle operates with the Asahi 25-1 valve and supports either fail-open or fail-closed positioning depending on installation, aligning with Worcester Series 44 style valve assemblies. Construction uses an industrial three-piece ball valve platform; body configurations may be thermoplastic or stainless depending on the valve build, and process piping connections vary by assembly. Applications include chemical processing, water treatment facilities, compressed air lines, and general industrial manufacturing where reliable manual isolation and automatic return are required. Media compatibility covers water, chemicals, compressed air, and other compatible industrial fluids. Common replacements include Flowserve Worcester Spring Return Valve Assembly and Asahi Spring Return Ball Valve.
