RACK & PINION KINEMATICS

DOUBLE ADJUSTMENT

DA DOUBLE ACTING

SR SPRING RETURN

1. Energized and self-lubricated strips.

Less friction between piston and cylinder.

It prevents the bonding of the seal to the cylinder even after long periods of inactivity.

2. Adjustment cam made by steel.

Possibility to adjust the closing and/or opening with a standard actuator (± 5° for each adjustment).

Simplicity and reliability of adjustment.

3. Transformation of linear motion into rotary motion using Rack and Pinion kinematics.

Linear torque (BTO & BTC), suitable for ball valves.

High adjustment precision thanks to the rigidity of the rack and pinion system and the mechanical stop between cam and adjustment grub screw.

Uniform rotation speed.

4. Rolled cylinder.

Less wear of the energized ties thanks to the low roughness of the surface (0.15 μm Ra).

5. Cartridge spring modular system.

High configuration flexibility and precision of the torque generated by the springs.

High range of configurations.

NAMUR interface for solenoid valves can be available on complete range.

With plate reported from RK10 to RK240. - Integrated for RK 300 and RK480.

NPT air hole threads available on request.

With plate reported for all sizes.

100% in- house manufacturing process technology.

Maximum control and accuracy in all the stages of the manufacturing process.

ATEX compliance.

Installation is allowed in a potential explosive environment.

Up to SIL 3 Certified.

Guarantee of the high level of functional safety.

WORKING PLANE
Supplying air through the air connection 4, the pistons move towards the center and shaft rotate in a clockwise direction.
The above drawing shows the final position.

WORKING PLANE
Supplying air through the air connection 2, the pistons move outwards the center and shaft rotate in a counter-clockwise direction.
The above drawing shows the final position.

INSTRUCTIONS FOR ADJUSTING THE STROKE OF THE DOUBLE ACTING ACTUATOR

OPENING ADJUSTMENT

CLOSING ADJUSTMENT

A) Check that there is no pressurized air in the actuator (in both chambers).
B) Loosen locknut A1.
C) Supply air to hole “2” (sufficient only for movement) the pistons will be in the end of stroke.
D) Screw or unscrew the screw A with an Allen key for the desired adjustment (maximum adjustment range ± 5°).
E) Once the adjustment has been made, with an Allen key stop the screw A, at the same time with a wrench tighten the locknut A1.

N.B. If necessary, repeat the operations until the desired setting is obtained.
