2 SYSTEM DESCRIPTION

2.1 General description

The Type 3003 electrical actuator is designed as an electromotive rotary on/off or
control actuator for ball or flap valves. The materials used ensure maintenance-free
operation and a low thermal load.
Due to its modular construction, the basic device can be extended with many options.
It is available for continuous or three-phase current with different torques for 20 Nm,
35 Nm, 60 Nm, or 100 Nm of torque.
All actuators are equipped with a standard emergency manual control and two additi-
onal limit switches, and are tested by the manufacturer. The limit switches are set for a
90° operating range so that configuration is unnecessary.
