Compact quarter-turn actuator from habonim-vaas is a unique patented design offering superior performance features with very low maintenance requirements. Smaller and symmetrical in shape compared to conventional two piston designs, it allows for vibration free mounting on valves, dampers and similar quarter-turn equipment. With relatively shorter strokes, it delivers maximum torque for minimum air consumption. Shorter stroke also means faster operation for high cycle requirements. Features up to 2600 nm in 8 models; patented four piston rack and pinion mechanism; short stroke quick acting; anodized interiors with two-layer polyurethane painted exteriors for high corrosion resistance; concentric springs offering wide torque range; and interchangeable body for double-acting and spring-return versions.
