GT range single- and double-acting pneumatic piston actuators (rack and pinion) for rotary valve control. The unique and compact design allows configuration change from single-acting to double-acting, even in the field. GT actuators provide a wide range of torque outputs in different body sizes. Standard 90 degrees action with optional 120, 180, 240 degrees or custom angles. All models incorporate an anti-blowout design and are available with an extensive list of options to optimize the actuator for particular applications.
Rack and pinion actuator.
The GT range of pneumatic rack & pinion actuators has been proven by a 30-year history of service in hundreds of thousands of installations encompassing a variety of diverse applications. There are a wide range of body sizes available in both double-acting and spring-return configurations. Units can be easily changed from one to the other – even in the field. In addition to the usual 90 degree rotation, 120, 180, and 240 rotations are also available. All models incorporate an anti-blowout design.
Many options are available to optimise the actuator for particular applications. Options include high- and low-temperature versions, anti-corrosion materials and treatments, valve mounting kits, and declutchable manual gear overrides.
We can also supply actuator control and indication components for virtually any functional requirement and installation environment. Accessory mounting conforms to NAMUR specifications and valve mounting dimensions are per ISO 5211 standards.
