Pneumatic valve actuator AP series

90°rack-and-pinionpiston

We supply pneumatic actuators with an very good price and a high quality. We have double- and single-acting actuators in stock. These are ATEX approved. Our standard Best-Torque actuators type AP, a rack and pinion design, are supplied in 2 different types, double acting (12 types) and single acting (11 types). In a rack and pinion type actuator the lineair kinetic energy is directly transformed into a “quarter turn” operation with a constant output torque over the full stroke. Both double acting and spring return actuators have twin cylinders horizontally opposed and incorporate piston guides to ensure correct contact between rack and pinion, at any pressure. High quality materials are employed throughout the construction and, the compact design is readily fitted to any type of valve. The actuators our suitable for both indoor as outdoor use.
