Scoth yoke pneumatic actuatorr

发布时间:2018-08-08     来源:艾德威尔•瑞拓
The scoth yoke pneumatic actuatorr is a piston type actuating mechanism, which is suitable for the switch cutting or metering control of the valve (such as ball valves, butterfly valves and cock valves) with 90 degree angle.
The scoth yoke pneumatic actuatorr refers to a pneumatic actuator with single cylinder, double piston and variable torque.
Working principle of fork lift pneumatic actuator
Scoth yoke pneumatic actuatorr 

The compressed air enters the cylinder and drives the piston to move in a straight line. The piston passes the piston pin and the fork U groove to turn the straight motion of the piston to the rotation of the fork, and the fork rotation drives the output shaft to rotate, thus realizing the control of the valve.

Product classification of  scoth yoke pneumatic actuatorr 
According to the different types of action, it can be divided into single acting scoth yoke pneumatic actuatorr  and double acting fork pneumatic actuator. The switch action of the actuator is completed by the gas drive, which is a double acting  scoth yoke pneumatic actuatorr ; only the opening action is completed by the gas source, and the switch is a single acting  scoth yoke pneumatic actuatorr  as a spring reset.
According to the different structure, it can be divided into single cylinder piston type and double cylinder piston type.
According to the main material, it can be divided into aluminum alloy, stainless steel, carbon steel and so on.
When gear torque is higher than 7000Nm, rack and pinion actuators are often not cost-effective. For this reason, it is generally recommended to choose high-power scoth yoke pneumatic actuatorr in the selection of pneumatic actuator, which can provide higher torque output.
The high power  scoth yoke pneumatic actuatorr  symmetrical and inclined steel fork mechanism allows two types of torque output characteristics. Among them, the inclined steel fork mechanism, with very high starting torque, low operating torque, suitable for control of butterfly valve; symmetrical steel fork mechanism, with a more balanced torque curve, mainly applicable to the control of ball valves and cock valves.
