The HG series scotch yoke pneumatic actuator the latest design scheme and is a safe and reliable driving mechanism for operating switch or regulating ball valves, butterfly valves, plug valves, and other 0 °~90 ° rotating mechanical devices. The design feature of modular structure makes the product components highly interchangeable, easy to maintain and reduce costs. The connection size and torque range of the actuator base are designed based on the ISO5211 standard. The actuator can provide a torque output of up to 250000 Nm (184000 foot pounds), with cylinder diameters covering 160mm-1000mm. It features a fork design that significantly reduces lateral loads, greatly enhancing performance. HG series pneumatic actuators are widely used in industries such as food, chemical, power, papermaking, petrochemicals, steel, municipal, and water treatment.

●The connection size and torque range of the actuator base are designed based on the IS05211 standard.
●The actuator can provide a torque output of up to 250000 Nm (184000 ft pounds) and features a fork design that significantly reduces lateral loads, resulting in significantly enhanced performance.
●The design feature of modular structure makes the product components highly interchangeable, easy to maintain and reduce costs.
●Configure the corresponding materials according to the temperature range used by the actuator to meet different working conditions and environments.
●The cylinder module with built-in guide rod solves the problem of local wear of the piston seal caused by its own weight and lateral force of the shift fork, ensuring the long-lasting and stable output of the actuator.
●Full range of manual operating mechanism options: handwheel, gear transmission, and hydraulic specifications.
●The optimized transmission module and torque ratio have higher compatibility with valve torque.
●The fork drive adopts oil-free lubricated bearings made of aluminum bronze composite graphite, which have stable and durable performance.
●Partial connecting shaft holes are connected with square shafts to improve accuracy, especially suitable for regulating (control valve) applications.
●Single action failure opening or failure closing is achieved by changing the direction of the cylinder and spring module, which is efficient and convenient.
