Pneumatic valve actuator series

HYC气动执行器

Design Features
The QH series pneumatic actuators are developed, developed, and designed based on the application of new technologies, materials, processes, and innovative concepts. They have the following characteristics:
1. Fully comply with new international standards such as IS05211, DIN3337, VD/NDE3845, and NAMIJR.
2. The extruded high-strength aluminum cylinder body has undergone fine grinding and hard anodizing treatment on the inner surface. Long service life, low friction coefficient, and quick action.
3. The beautiful, compact, and modern design, as well as the multi specification series of products, make the selection more cost-effective.
4. All active surfaces are made of high-quality bearings with low friction, long lifespan, and no noise.
5. Two independent stroke adjustment mechanisms are installed externally to facilitate adjustment of the ± 5 ° fully open or fully closed position.
6. The actuators with the same external structure are available in double acting and single acting (spring return) options, making it easy to install all accessories for output.
7. The multifunctional position indicator of the NAMLJR standard can be used as a visual indicator.
8. Pre compressed load spring, safe and convenient installation and disassembly.
9. The piston and end cover are made of die-cast aluminum alloy, with high strength and light weight.
10. Changing the sealing material can be applied to high or low temperature situations.
11. Multiple angular strokes (such as 120 °, 135 °, 180 °, etc.) and three position pneumatic actuators can be provided as needed.
12. No connecting plate is required. The solenoid valve can be installed directly.HYC double acting actuator output torque

Working principle (standard action)

The above schematic diagram indicates that the torque value of the dual action actuator remains constant throughout the entire stroke. Users can select the appropriate actuator model based on their specific requirements and refer to the following content:
1. Clarify the larger torque value of the operated valve;
2. Increase the torque value by 25% to 50% with a set coefficient (depending on the valve type and process conditions);
3. According to the provided torque value, refer to the torque table and the corresponding air pressure value. The obtained torque value should be equal to or exceed the provided torque value;
After the torque value is determined, move horizontally to the "Model" column and find the desired actuator model.

The schematic above shows that the torque of the spring return actuator is not constant but gradually decreasing. The main reason is that the spring is compressed during the air stroke stage due to the movement of the piston, while accumulating energy obtained in a continuously decreasing manner during the motion conversion process. The torque of the actuator is defined according to the following four basic values:;
Air stroke: Start: actuator torque in spring released state             End: actuator torque in spring compression state
Spring stroke: Start: Torque during spring compression                                    End: Torque when the spring is released
Users can select the appropriate actuator model based on their specific requirements and refer to the following content:
1. Clarify the larger torque value of the operated valve;
2. Increase the torque value by 25% to 50% and set a safety factor (depending on the valve type and process conditions);
3. Based on the provided torque values, refer to the torque table and the corresponding air pressure values. The obtained torque value should be equal to or exceed the provided torque value, and in addition, the minimum value between the end of the air stroke and the end of the spring stroke should be taken into account;
After the torque value is determined, move horizontally to the "Model" column and find the desired actuator model.
