●The HG series scotch yoke pneumatic actuator adopts 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 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.
