The interlock systems for actuated valves are supplied to suit electric, hydraulic or pneumatically operated valves.
The interlock system accommodates both the local and remote models of operation. A local control panel interface, manual operation or override interlock and a valve position providing device ensure the actuator manual override cannot be used to override the Interco function. On electrical actuators, the electrical circuitry remains fully functional
