The straight stroke pneumatic actuator developed and produced by Haidun Valve is a curved arm piston actuator. Compressed air pushes the piston to move in a straight line through a cylinder, and then converts the piston's linear motion into angular rotation through a connecting rod and a curved arm. This actuator has high rotation accuracy, small backlash and dead zone, and high sensitivity in the control process. It is mainly used for angular stroke control valves. At the same time, due to its large output torque range and complete specifications, it is used for controlling angular stroke switching valves. It is a multifunctional actuator that can be applied to almost all angular stroke valves.

Product features:

1. High rotation accuracy: All rotating parts are equipped with high-precision bearings.

2. Long service life: For smaller actuator cylinders, aluminum alloy cylinders are selected, with special wear-resistant treatment on the inner surface. The surface of the piston rod is plated with hard chromium and then mirror polished. The piston adopts a guide belt and a dual sealing design.

3. Strong impact resistance: The curved arm adopts an integral casting structure, which has high strength, good stability, and strong impact resistance.

4. Convenient adjustment of stroke range: By adjusting the stroke adjustment bolts on both sides of the actuator, the 0 ° and 90 ° positions of the actuator can be adjusted within ± 10 °.

5. Safe and reliable: The pneumatic single acting actuator is equipped with a structure to prevent the spring from popping out, making the use of the actuator safer.

6. Modular design, more options: The housing and cylinder components are designed as two modules, which can be combined according to torque requirements to achieve small output torque levels, multiple levels, and flexible selection.

7. Can achieve fast opening and closing: When used in conjunction with pneumatic components, it can achieve fast opening and closing.

8. Curved torque output: The actuator outputs a large torque when the valve is opened and closed, exceeding the nominal rated output torque of the actuator, resulting in a higher safety factor of the actuator
