Easy testing July 1st 2004 Easi-Test from Smith Flow Control is fitted between valve and actuator to permit the independent testing of pneumatic actuators and process valves on live systems. It makes testing of both declutchable and automatically clutchable valves a simple procedure.
A lever tool automatically disengages actuator from valve stem. The valve can then be operated like a traditional manual valve whatever the position of the actuator or the live process condition. When the valve is declutched, it can be locked in any position, allowing maintenance, function testing or changeout of the actuator without interrupting the process or compromising the process management system.
