Use Electromotoric actuators to operate Siemens combi valves for type series VPF43.. and VPF53.. with 20 mm stroke, as control valves on ventilation, air conditioning, district heating and refrigeration plants. Functions Function Description 3-position control A 3-position signal controls the actuator via connection terminals Y1 or Y2. The desired position is transmitted to the valve. SAX31P03, SAX81P03 Modulating control The modulating positioning signal provides stepless motor control.

SAX61P03 Up to 10 actuators can drive in parallel on a controller output with a rating of 1 mA. Modulating actuators have an input impedance of 100 kΩ. SAX61P03/MO The Modbus converter is designed for analog control at 0...10 V. Keep the analog signal setting on the actuator as is (switch 1 to OFF); adjustment not permitted. ASZ7.5 Actuators with a DC 0...9.8 V feedback signal are recommend for the combination SIMATIC S5/S7 and position feedback. Signal peaks in potentiometer ASZ7.

Operation Direction of control action On valves where the stem retracts to the close position, "direct acting" means that the value is fully closed at positioning signal Y = 0 V or Z = 0 Ω (i.e. 100 %). Direct acting Y, Z Positioning signal V Volume flow Positioning signal Y DC 0...10 V, 4...20 mA Positioning signal Z 0...1000 Ω Control action: Direct acting Maintenance The actuators are maintenance-free.
