The Sonic Torque Pneumatic Actuator Series 4×4™ packs more than double the torque of conventional rack and pinion actuators. That ís because it has four  pistons generating torque around a centrally located pinion. With more pistons in the actuator, it allows their diameter to be smaller while generating higher torque. At the same time, it means the size of the actuator can be more compact.

Habonim Compact Valve Actuators

Habonim is proud to introduce its new generation actuator. Based on patented 4 piston technology, the Compact II is the most rugged actuator on the market.

Habonim Compact valve actuators are compact in both size and weight. The racks are centered to the piston, thus eliminating side loads. The actuators are designed with maximum safety features for operators and maintenance teams (No pre – load on springs).

Habonim Impact spring Assist

The Impact Spring Assist is a pneumatic device whose purpose is to increase spring closing torque on spring return actuators. This is achieved by diverting the spring chambers so that in combination with the spring force an increase in the total closing torque of the actuator is achieved. Redirecting the air pressure into the spring chamber increases the spring end torque by 50% and more.
