Heavy Duty Pneumatic Actuator
Heavy Duty Pneumatic Actuator
Item Number:HPA-G
The HPA-G series shift fork actuator is built in line with the latest design solution and is a safe and reliable driving mechanism for operating on-off or regulating ball valves, butterfly valves, plug valves and other 0°~90° rotating mechanical devices.The connection dimensions and torque range of the actuator base are designed based on ISO5211 standards .The actuator can provide a torque output of up to 250,000 Nm (184,000 foot-pounds), and its shift fork design significantly reduces lateral loads, thus greatly enhancing performance. Its modular structure design gives the product parts great interchangeability, making the product easier and cheaper to use and maintain. Configure the corresponding materials according to the operating temperature range of the actuator to meet the working conditions of different occasions.
Description
HPA-G series pneumatic actuator is a scotch yoke angular-turn actuator, which is divided into double-acting and single-acting (spring return), driven by compressed air source, fork-type transmission structure, large output torque, flexible and stable action. Modular optimization design is adopted, mainly composed of a drive module, pneumatic module, spring module, and manual module.
The U-shaped curve characteristic output torque of HPA-G series pneumatic actuators is more suitable for the switch and adjustment of large-diameter ball valves and butterfly valves, and can also be used for other partial rotary drive occasions.
