ABSTRACT:
An emergency shutdown valve actuator includes a support and a fluid activated actuator drive secured to the support. Clamps are provided for clamping the support onto a tubular member. A drive key is provided which is adapted to couple the actuator drive and a female receptacle of a valve member, such that movement of the actuator drive is transmitted via the drive key to the valve member to move the valve member between an open and a closed position. The actuator drive is coupled to a fluid source controlled from a remote control panel such that fluid is supplied to activate the actuator drive in the event of an emergency.
