C: Rack & Pinion actuator

Designed for less demanding applications and operation of ball valves, butterfly valves, plug-in valves and other quarter-turn devices.

  • Stroke adjustment for open position
  • Double action field: from 21 to 4803 Nm (6 bar)
  • Return spring range: 7 to 1888 Nm (6 bar)
  • Temperature: -20 to +80°C (-4 to +176°F)

Benefits

1. Springs

The springs are located inside the piston rack, the same overall dimensions for DA and SR actuators (size 2 – 150).
No special tools are required to switch from DA to SR or vice versa
Long tightening is standard to completely relax the springs

2. Wear-resistant bearings

“POM” anti-wear pads encapsulated on the piston, prevent contact between the piston and cylinder, thus ensuring low friction.
“POM” double-encapsulation anti-wear pads absorb the adverse lateral load at the beginning of each start.

3. Twin guide bars

Twin guide bars absorb any lateral load, reducing wear.

4. Support bearings

The piston support bearings, located behind the piston o-ring, ensure a linear motion and prevent cylinder surface wear.
