RACKON
RACK AND PINION PNEUMATIC ACTUATOR
RACKON is Omal’s new rack and pinion pneumatic actuator. Available as both double acting and spring return. NAMUR interface for solenoid valves can be available on complete range. 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.
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.
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.
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.
Rolled cylinder.
Less wear of the energized ties thanks to the low roughness of the surface (0.15 µm Ra
Cartridge spring modular system.
High configuration flexibility and precision of the torque generated by the springs.
High range of configurations.

VIP EVO
COAXIAL VALVE
https://www.omal.com/products/pneumatic-valves/vip-evo/vip-evo-pn40-580-psi.html
The pneumatic coaxial valve "VIP EVO" is the evolution of the "VIP" valve. "VIP EVO" is an interception valve (between pipe IN-OUT) with built in control system. It works thanks to the internal movement of a piston supplied with air. At the end of its stroke (VIP EVO valve is an ON/OFF valve), the piston presses on the seat seal, stopping the fluid from flowing, or moves away from the seal, allowing the intercepted fluid to flow. As the seat is perfectly tight and the intercepted fluid pressures discharge on it, the pressure necessary to move the piston is little affected by the fluid pressure. As a result, OMAL has been able to design a light space saving and lasting valve. Internal fluid-dynamics has been designed to reduce turbulence and pressure loss.
Several seal materials available.
Maximum compatibility with different types of fluids depending on the seals used (EPDM, NBR, FKM).
No external moving parts.
No risk of injury due to moving parts. Easy mounting.
Long life time guaranteed.
Lifetime up to 10 times longer than a ball valve with reduced maintenance costs.
Less Air consumption.
70% less air consumption compared to an actuated valve with SR pneumatic actuator therefore less load on the compressor or the possibility of using a smaller sized compressor.
