Product Description

Scotch Yoke Modulating Spring Return Model Double Acting Pneumatic Actuators
Product Description

1. AKW Scotch Yoke Pneumatic Actuator Overview
AKW pneumatic actuators are divided into double-acting and single-acting (spring return), two split cylinders, large output torque, flexible and stable action; the piston rod is hard chrome plated, with good anti-abrasiveness; all sliding parts are equipped with oil-free lubricated bearings or guide rings to reduce the friction coefficient and extend the service life.

The C-curve characteristic output torque of AKW pneumatic actuator is more suitable for large-diameter ball valves and butterfly valves. It is widely used in various valves such as regulating valves, ball valves, butterfly valves, gate valves, slurry valves, stop valves, and plug valves. It is an ideal device for realizing remote centralized or individual control of industrial automation pipelines.

Product Parameters

3. AKW Scotch Yoke Pneumatic Actuator Structure
Scotch Yoke Modulating Spring Return Model Double Acting Pneumatic Actuators
A: Output shaft
The output torque is large, the action is flexible and stable; the piston rod is hard chrome plated, which has good wear resistance; all sliding parts are equipped with oil-free lubricated bearings or guide rings to reduce the friction coefficient and prolong the service life
B: Handle Wheel
When the circuit or gas line is cut off or there is a fault, the valve will automatically close or open by the spring, and the handle can be turned to open or close the valve.
C: Adjustment screws
Two separate adjustment screws on the outer side are more accurate and convenient for the actuator installed on the valve to adjust the open and closed position of the valve. If full stroke adjustment is required, longer adjustment screws are also configured on the two end covers.
D: Cylinder
The cylinder body is made of ductile iron, the inner surface is coated with PTFE, and the inner hole is precisely machined, which has a longer service life and a low friction coefficient.
E: Connection size
Complies with international ISO5211 standards
F: Spring cylinder
When the circuit or gas line is cut off or there is a fault, the valve automatically closes or opens by the spring (it cannot be disassembled without the guidance of professionals)
G: Cast Box 
Built by ductile iron

4. AKW Scotch Yoke Pneumatic Actuator Functions and Accessories
Double-acting pneumatic actuator: two-position control of valve opening and closing.
Spring reset type: when the circuit or gas line is cut off or there is a fault, the valve automatically opens or closes.
Single-electric solenoid valve: the valve opens or closes when the power is supplied, and closes or opens when the power is off (explosion-proof type is available).
Double-electric solenoid valve: the valve opens when one coil is energized, and the valve closes when the other coil is energized, with memory function (explosion-proof type is available).
Limit switch feedback device: long-distance transmission of valve switch position signal (explosion-proof type is available).
Electrical positioner: according to the current signal (standard 4~20mA) size, the medium flow of the valve is regulated and controlled. (Explosion-proof type is available).
Pneumatic positioner: according to the air pressure signal (standard 0.02~0.1Mpa) size, the medium flow of the valve is regulated and controlled.
Electrical converter: converts the current signal into an air pressure signal, and is used in conjunction with the pneumatic positioner (explosion-proof type is available).
Air source processing triplex: including air pressure reducing valve, filter, oil mist collector, which can stabilize the air source pressure, clean and lubricate the moving parts.
Manual operation mechanism: automatic control can be operated manually under abnormal conditions.
