  • Pneumatically drivable valve actuator and method of locking a valve closure element relative to a valve body
    Patent number: 9746100
    Abstract: The present disclosure provides a pneumatically drivable actuator for setting a position of a valve closure element in a valve, comprising a piston, which is moveable in a pressure chamber by influence of a drive gas, and a locking mechanism for mechanically locking the piston relative to the pressure chamber. The actuator further comprises a ventilation device for venting the drive gas from the pressure chamber while the piston is mechanically locked relative to the pressure chamber, such that pressurization of the pressure chamber is prevented. A method of locking a valve closure element relative to a valve body of a valve that is controllable by a pneumatically driven actuator is also disclosed.
