Function and Design

Actuator with linear torque curve. Three point controlled of the pistons for low friction between the body and pistons. Mounting holes according to ISO 5211 and DIN 3337, for standardized mounting to the valve. End caps with adjustable screws for stroke length (5°). Mechanic end points as a standard. The piston force is transfered through the rotary axle to the valve stem (90° + 1°-0,5°). Actuator top and solendoid valve connection according to NAMUR (VDE/VDI 3845).

Actuators Actreg AT 3831 single acting:
The actuator is provided as a standard with spring closing function. If a spring opening function is required this has to be stated when ordering.

Accessories and Options

Accessories

  • Visual position indicator.
  • Emergency gear shift between actuator and valve.
  • Internally connected pressurized air tank for emergency operation.
  • Block for control timing
  • Valve block for air evacuation from the acuator without dissassembly of the control air lines.
  • Inductive or mechanical limit switch.

Installation

The actuator can be installed indoors or outdoors in any position. All though mounting the valve with the air connections upwards should be avoided to minimze the risk of water and dirt to get inside of the valve.

Maintenance and spare parts

The actuator should be disconnected electrically and pneumatically before assembly or dissassembly is started. The actuator should be mounted with even spaced distances.

Spare parts
The repair kit includes the neccessary soft parts.
