Advantages of a scoot-type pneumatic actuator

Advantages of Scotch Yoke Pneumatic Actuator  1. A brief introduction toScotch Yoke Pneumatic Actuatoris a piston actuator; For example, the commonly used imported fork pneumatic actuator of VTON is suitable for switching off or metering control of valves with 90° angle (such as ball valves, butterfly valves, plug valves), especially for the control of large-diameter and high-torque valves. Scotch fork pneumatic actuator usually refers to a pneumatic actuator with a structure of "single cylinder and two pistons-variable torque scoot fork". Second, the working principle of the fork pneumatic actuator: compressed air into the cylinder, promote the imported fork pneumatic actuator piston for linear motion, the piston through the piston pin and fork U-groove design to convert the linear motion of the piston into the rotary motion of the fork, the fork rotation drives the output shaft to rotate, so as to realize the control of the valve. 3. The classification of rattle fork pneumatic actuators can be divided into imported single-acting fork pneumatic actuators and imported double-acting fork pneumatic actuators of American Weiton VTON according to different types of functions. The switching action of the actuator is completed by air source drive, which is a double-acting scootch fork pneumatic actuator; Only the opening action is completed by the air source drive, and the closing action is a single-acting fork pneumatic actuator as a spring return. According to the different structures, it can be divided into single-cylinder piston type and double-cylinder piston type. According to the different main materials, it can be divided into aluminum alloy type, stainless steel type, carbon steel type, etc. Rack and pinion actuators are often not cost-effective when torque requirements above 7000Nm. For this reason, it is generally recommended to choose a high-power fork pneumatic actuator when choosing a pneumatic actuator, which can provide a higher torque output. High Power Scotch Fork Pneumatic Actuators Symmetrical and Angled Steel Scotch Fork Mechanism Allows for Two Types of Torque Output Characteristics.Among them, the inclined steel fork mechanism has a very high starting torque and low running torque, which is suitable for the control of butterfly valves; The symmetrical steel fork mechanism has a more balanced torque curve, which is mainly suitable for the control of ball valves and plug valves. 4. Advantages of the fork pneumatic actuator 1. The fork pneumatic actuator not only meets the explosion-proof requirements, but also has a small size, light weight and large torque, because it adopts a unique "single cylinder double piston-fork variable torque" transmission structure design. As a single-cylinder design, the fork pneumatic actuator is undoubtedly half smaller than the two-cylinder design of the rack and pinion actuator. 2. When the fork pneumatic actuator is operating, the output torque can change with the change of angle, and the torque value is the largest in the open or closed position of the valve, which is exactly in line with the law of the valve. Compared to rack and pinion actuators, pneumatic actuators with scotch forks are more torque-saving, because the torque of rack and pinion actuators is constant. 3. The fork pneumatic actuator is a symmetrical design. The maximum output torque is at 0 degrees and 90 degrees. The output torque in the middle position is minimal. Corresponding to the torque characteristics generated by ball valves; 4. The fork pneumatic actuator adopts an inclined design, which can output a larger starting torque. It is more in line with the torque characteristics of butterfly valves; 5. The cylinder wall of the imported scootch pneumatic actuator of VTON adopts hard chrome plating process to ensure a longer practical life; 6. The track of the fork pneumatic actuator is treated with high-frequency quenching and grinding, and the slider adopts a square self-lubricating process, which can ensure permanent practicability; 7.Scotch York pneumatic actuator  DRG series actuator has a complete set of installation accessories, including: manual handwheel, hydraulic manual, limit switch,Solenoid Valve, positioner and other control components.
