Our manual override gearbox is designed to fit between a pneumatic actuator and a quarter turn control valve and conforms to ISO 5211 interface standards. The special feature with our model is an isolation valve that cuts off the air supply to the actuator when the override is engaged and also exhausts any air left in the actuator. This allows the valve to be manually operated at any time with complete safety. Without this isolation valve air pressure could be reinstated while the override is engaged causing damage or injury. A spring loaded locking pin prevents the engagement lever being operated accidentally and locks it in the engaged or disengaged position.
