YCG Series Heavy-Duty Air Actuator
Description of Scotch Yoke Air Actuator
YCG Series Heavy-Duty Air Actuator is a gas-powered source developed by Yuechi Flow Control. with a modular structure design. It can be flexibly replaced with pneumatic modules or spring reset modules on both sides of the cabinet. Industrial control valve drive mechanism with single-acting and double-acting functions. All parts of the product are produced by a precision CNC machining center to ensure the accuracy of each part. At the same time, hydraulic manual operation, solenoid valve, limit switch, and other accessories can be selected, which are widely used in valves with 90-degree rotation for different working conditions.
Working Principle of Dual Acting Fork Air Actuator
| When the compressed gas source enters the cylinder from the air hole (A), the gas on the other side of the piston is discharged from the air hole (B) on the other side of the cylinder, and the fork rotates the valve stem to rotate counterclockwise. at which time the valve opens, lf the solenoid valve is reversed, when the compressed gas source enters the cylinder from the air hole (B), the gas on the other side of the piston is discharged from the air hole (A). pushing the piston to move in the opposite direction, and the fork moves the valve stem to rotate clockwise. shut down. | When the single-acting pneumatic control valve is installed in the conveying pipeline, it should pay attention to the normally closed or normally open mode, and the cylinder module and the spring module on both sides of the driving box can be interchanged to realize the mode interchange; when the compressed air is from the right side of the cylinder (A) When the air hole enters, the gas on the left side of the piston is discharged from the (B) air hole, pushing the piston to the outside, driving the fork to rotate counterclockwise, and compressing the spring, at this time opening the valve when the compressed air is from the right side of the cylinder (A) When released, the spring automatically returns to the position and drives the fork to rotate clockwise. The left side of the piston (B) is vented to balance the air pressure to achieve valve closing |
