Hydraulic Actuators Features:
Hydraulic Actuators are divided into double acting and single acting (spring reset), two split cylinder, the output torque, flexible movement balance; piston rod hard chrome plated, a good wear And all the sliding parts are equipped with oil-free lubrication of the shaft to reduce the friction coefficient, to extend the service life of the hydraulic actuator U-curve characteristics of the output torque is more suitable for large diameter ball valve, butterfly valve and other corner of the valve, Closed and adjustable, can also be used for other rotary motion occasions, is to achieve industrial pipeline automation control of the ideal device. 

When using hydraulic actuators, first determine the valve opening and closing torque, and then according to the valve using the fluid medium, increase the safety value. Increases the safety value by 20% for clean and lubricated media; Increases the safety value by 25% for water vapor or non-lubricating media; 60% safe for non-lubricated dry media; non-lubricated gas-laden granules Increase the 100% safety value. And then according to the air source working pressure, find double acting or single acting output torque table, feasible to the accurate actuator model. Single acting output torque table, the minimum spring torque Detention when the valve off the valve, the spring torque is to open the valve when the torque.
