> Valve Actuator > ACTUATION

Habonim’s unique quarter-turn CompAct actuators have superior performance of double the torque per size, much longer cycling before any maintenance, high opening and closing speed
and extraordinary durability in the most demanding industrial environments. Our CompAct actuators are successfully used to supply control packages in diverse industries and applications that are superior in overall smaller size, with less weight, less compressed-air
consumption, much more reliable especially in high cyclic applications and with very short acting times.

Habonim actuators product line is subject to the company’s regulation, methodologies and certification – for more information, see Habonim Introduction chapter.

The COMPACT actuator is a quarter-turn rack & pinion pneumatic actuator that doubles the torque of standard pneumatic actuators. The superior performance is achieved by Habonim’s patented four piston design, which generates torque around a centrally located piston. This translates into double the power for the same size actuator or half the size for the same amount.

Pistons with balanced centralized forces of pistons on pinion

Double the torque of same sized regular actuator
Less wear & tear on moving parts
Longer sealing with no maintenance
Shorter and smaller pistons with shorter travel distance
Compact square shape with minimized footprint

Shorter open/close time – allows superior ESD functionality

Smaller air consumption
Lightweight

Four short spring sets – up to three nested springs against each cylinder

Selection of springs mix to provide flexible spring torques for the available air supply pressure
Spring cartridge option provides higher torque with better characteristics for opening or closing
Redundancy in case of spring failure – the other three springs will maintain rotation

Habonim patent innovative four-piston scotch-yoke design combines the benefits of high-power scotch-yoke mechanism to generate maximal power and high Start and End torques, where most valves require it and the balance and compactivity of the four-piston mechanism to provide fast and efficient operation with minimal maintenance. The patent four-piston scotch-yoke pneumatic actuator provides almost 100% higher power-to-size ratio. In other words, a comparable traditional high-torque scotch-yoke actuator will be twice as big as a Power CompAct unit. The Power CompAct unit is much faster in opening and closing and uses less compressed air to operate. The evenly balanced forces of the four pistons and short travel (short piston) provides un-matching high cycle long life without maintenance for hundreds of thousands of operations.
