► Rack & Pinion Actuators

Pneumatic actuators

New ATD series pneumatic actuators are adopted, with double-acting and single-acting (spring return), gear transmission, safe and reliable; large-diameter valves adopt AW series pneumatic actuators fork-type transmission, with reasonable structure, large output torque, and Double acting and single acting.

1. Gear type double piston, large output torque and small volume.

2. The cylinder is made of aluminum-gold material, which is light in weight and beautiful in appearance.

3. Manual operating mechanisms can be installed on the top and bottom.

4. The rack-type connection can adjust the opening angle and rated flow.

5. The actuator can be equipped with electric signal feedback indication and various accessories to realize automatic operation.

6. IS05211 standard connection provides convenience for product installation and replacement.

7. The adjustment screws at both ends can make the standard products have an adjustable range of ±4° at 0° and 90°, ensuring the synchronization accuracy with the valve.

Accessories options

The following accessories can be selected according to different controls and requirements:

Echo device: also called limit switch, remote feedback switch signal (optional explosion-proof).

Solenoid valve: double-acting 5/2-way, single-acting 2/3-way (optional explosion-proof).

Triplet: It can stabilize the air source, filter, and add lubricating oil to the cylinder.

Handwheel mechanism: Turn the handwheel mechanism to manually open and close the valve.

Electric positioner: input 4～20mA signal to realize valve adjustment function.

Ordering Instructions

1. Pneumatic actuator type: double-acting, single-acting

2. Medium type, temperature, pressure

3. Required accessories: solenoid valve, positioner, signal feedback, air source processing triplet, manual mechanism

► Construction of pneumatic actuator

Actuators shall be of rugged pneumatic Rack & Pinion Design. Actuator body should be hard anodized to promote long cycle life and corrosion resistance. The actuator body should incorporate a heavy duty, ISO 5211 valve mounting pad with multiple ISO FO bolt circles for ease of mounting. Actuator internals should include dual aluminum pistons for a balanced torque load and a one-piece plated blow-out proof pinion for operator safety. Actuator drive pinions should incorporate significant body housing bearings with heavy duty O-Ring seals to promote high cycle life. The unit should have a dual travel stop feature, with a minimum of 5° of stroke adjustment on both ends of travel, to accommodate numerous valve and damper
designs. All actuator fasteners and hardware should be stainless steel for corrosion resistance.The rack & pinion actuator line should be offered in a broad range of torque outputs. The actuator of choice should be AT Controls  Series Rack & Pinions.​
