Worcester 1SR-44 Spring-Return Handle - SURFACE RUST

Description:

The Worcester Controls 1SR-44 Spring-Return Handle is an industrial manual spring-return actuator handle used on Worcester Series 44 ball valves for fail-safe quarter-turn valve operation and process flow isolation applications. Commonly installed in chemical processing plants, water treatment systems, industrial manufacturing facilities, and fluid handling systems requiring reliable manual valve operation with automatic spring-return positioning. Maintenance technicians, process engineers, and industrial automation specialists use this spring-return handle for process isolation, safety shutoff applications, replacement maintenance, and industrial flow control systems. Surface rust may be present on surplus or used inventory but typically does not affect the functional operation of the actuator handle assembly.

Applications:

The Worcester Controls 1SR-44 Spring-Return Handle is designed for industrial process systems where dependable manual operation and automatic fail-open or fail-closed positioning are critical for operational safety and process reliability. It is commonly used in chemical processing systems, water treatment facilities, compressed air applications, industrial manufacturing lines, and process piping systems where spring-return valve handles help ensure valves automatically return to a preset position when released by the operator.
