Pneumatic actuator related data

Top connection size VDI/VDE3845NAMUR/standard, easy to box, positioner, and other accessories.

Flank connection size meets with VDI/VDE3845NAMU

R standard, suitable for install solenoid valves.

Bottom connection size meets with ISO5211 and DIN3337 standard, with square and star holes can be connected with the valve directly.

Double-acting Principle of Operation(Standard Steering)

When the air pressure from the A port force the piston to move separately toward the end cap direction, the air is discharged from the B port to obtain counterclockwise rotation.

When the air pressure from the B port forces the piston closed, the air from the A port discharge, so as to obtain clockwise rotation.

Single Acting Principle Of Operation (Standard Steering)

When the air pressure from the A port forces the piston to move separately toward the end cap while compressing the spring, the air is discharged from the B Port to obtain counterclockwise rotation.

Loss of air or loss of electricity, the spring closed the piston, the air discharge from the A, to obtain a clockwise rotation.

Double-acting Actuator Selection Example

When using the actuator, determine the valve torque plus safety factor, the valve safety with different media, temperature, pressure, the friction between the valve core and the valve, and many other factors, affecting the operating torque. Known butterfly valve torque=130Nm, the use of water for the medium: room temperature, on-site gas source pressure of 5 bar, to a safety factor of 20% Calculation: Safe Torque:130+20%=156Nm.ln the control double-acting actuator torque meter, check the pressure in the column of 5bar.Find the data equal to or similar to 156Nm along this column, select 162.9Nm, look for the model left, and then select the XM-AT105 Model.

Single Acting Actuator Selection Example

In the selection of first consideration of air pressure under the action of the moment and spring elongation under the torque.
Known butterfly valve torque=200Nm, the use of the medium for the steam: the use of temperature 160 ° C, on-site gas source pressure of 5.5 bar, to a safety factor of 25% Calculation: Safety Torque:200+25%=250Nm.
Control single action actuator torque meter: check the column pressure at 5bar, look for torque along the column(beginning and end), and then check to the right moment at which the spring stroke begins and ends. Check the results of the actuator model XM-AT160, spring 10, resulting in the following values:
Air pressure 0° =383Nm Air pressure 90° =277Nm
Spring stroke 0° =279Nm. Spring stroke 90° =385Nm
Note： Selected torque should be equal to or close to the safety torque!
