Smith Flow Control Ltd
Valve Interlocks are mechanical locking devices which can be fitted to any type of manual or actuated valve to prevent inadvertant or unauthorised operation.
The interlocks are used to implement 'sequential control' of process valves to ensure that critical operating sequences cannot be violated.
The "Easi-drive" portable valve actuator is available in Pneumatic, Hydraulic or Electric variants. It is used to operate large diameter manual valves in a fraction of the normal operating time without any risk of fatigue or injury to the operator.
Easi-drive's high torque operating guns can be used to free partially siezed valves.
