: The valve is remotely operated using compressed air. When air is supplied to the actuator, it moves a internal plug to either open or shut off the flow of product through the valve body.
: Many versions, like the i-SSV 51, use a spring-return mechanism . If compressed air is lost, the internal spring automatically returns the valve to a "Normally Open" (NO) or "Normally Closed" (NC) position to ensure process safety. Technical Specification Highlights ssv51l30wexe work
