HPAY Series Compact Scotch Yoke Pneumatic Actuator

Description of HPAY series Scotch Yoke Pneumatic Actuator

The HPAY series pneumatic actuator adopts a new scotch fork transmission structure, integrates the latest pneumatic actuator technology and application materials, and is innovatively designed based on rich field installation and product application experience.

Specifications & Features

High performance and high reliability
Better industrial shape is more suitable for various application environments
More applicable specifications and higher cost performance
Fully comply with the latest international standards

Materials and Component

1. Integrated universal compact design: Double-acting and spring return actuators of the same model have the same cylinder and internals, and can be converted on-site by adding or removing springs and replacing end covers, which greatly facilitates on-site applications.	2. Fully complies with the latest international standards including ISO5211, DIN3337 and VDI/VDE3845. Fully supports NUMAR standards, has good interchangeability, and is easy to install related accessories such as solenoid valve limit switches.	3. Double-piston fork structure design: It has the advantages of compact structure, large torque, fast and smooth action, etc. The steering can be easily changed by simply adjusting the pistons.
4. Two independent stroke adjustment bolts on the outside can easily and accurately adjust ±5 degrees in the 0 degree and 90 degree directions, so that the actuator is consistent with the valve position in the fully open and fully closed positions.	5. Composite bearings and guide rings on the shaft and piston ensure precise operation, low friction and long service life.	6. A special-shaped sealing ring design is used between the end cover and the cylinder body to avoid the rubber plug suction phenomenon that is easy to occur in conventional actuators, greatly improving safety, making the sealing performance more reliable and the service life longer.
7. The output shaft, fork plate, block and other bearing parts are made of high-strength alloy steel to ensure the safe and reliable operation of the actuator.	8. Combined pre-compressed spring seat, with special coated spring, suitable for a variety of occasions, safer and more corrosion-resistant.	9. Compared with the rack and pinion actuator, VTY improves the torque when opening and closing, and is lighter and consumes less air, thus saving the corresponding cost of the air compressor.
