Easi-Test from Smith Flow Control is a unique device that permits the independent testing of pneumatic actuators and process valves on live systems. Fitted between the valve and actuator, when activated it allows independent testing and operation of the actuator or valve.
Until now, function testing of actuated valves while a process was live has been extremely difficult, usually involving the simultaneous operation of both the actuator and valve. The operation also required a mechanism to depres- surise the actuator supply source.
Easi-Test overcomes these difficulties, making independent testing of both declutchable and automatically clutchable valves a simple procedure. Operating the Easi-Test involves the introduction of a lever tool which automatically disengages the actuator from the 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.
Easi-Test can easily be retrofitted and integrated into existing process systems. The assembly mounting/interface components are 316 stainless steel investment castings, profiled to adapt to standard ISO valve topworks.
