Pneumatic Actuators Asahi/America’s Series 79P pneumatic actuators for quarter-turn ball and butterfly valves provide accurate and dependable control, especially in corrosive applications. Double Acting: When the pressurized air, non-combustable gas or liquid is removed from Port A, the unit remains in the same position until pressurized air is applied to Port B (unlike the single acting actuator). When the pressurized air is introduced to Port B, it is channeled to the opposite side of the pistons. This pressure on the pistons drives them to their original position, which in turn rotates...

Pneumatic Actuators Actuator Selection Pneumatic Actuator Sales Questionnaire SCOTCH YOKE Torque and Air Pressure Two pieces of information are required for proper selection of a pneumatic actuator: First is valve breakaway torque. This is the amount of torque required to “break” the ball, plug or disc away from the seat. It is calculated from the differential pressure, type of media, contact area between sealing members, etc. Once this is determined, it is multiplied by a safety factor to take into account unknowns such as the amount of time a valve has been in the closed position (some...
