PNEUMATIC DIAPHRAGM ROTARY ACTUATOR
SINGLE ACTING TYPE
The “DB” rotary stem motion type diaphragm actuator, with single-spring design, offers dependable, high thrust performance in a compact, lightweight package. It obtains a required rotary output by converting a linear output into a rotation force through the scotch yoke construction. The linear output is created by balancing two forces.
The type “DB” is a yokeless, direct-acting diaphragm actuator for either throttling or on-off service. Principle applications include operation of butterfly and segmental ball valves, damper, and other similar equipment.
