Function and Design
Actuator with linear torque curve.
End cap with adjustable screw stroke (stroke 5°) for size 10-4000 as standard.
Drive shaft with internal connection for adapter size 10-4000 with removable connector. Mounting to valve is standard acc. to ISO 5211. Patented piston guide prevents fixation. Piston torque transmitted via drive shaft to the valve stem (90°
+1°–0,5°).
Bearings, preventing contact metal to metal, guarantee long life without lubrication.
Actuator top plate and solenoid plate connection acc. to NAMUR (VDE/VDI 3845).
Technical Information

Manoeuvre medium:
Supply pressure max 8 bar (e).
-30°C to +100°C. Other ranges on request.
Air or inert gases, purity at 40 micron.
(No requirements of mist lubrication). Oil or water.
