Use Electromotoric actuators to operate Siemens combi valves for type series VPI46.40F9.5Q and VPI46.50F12Q with 15 mm stroke, as control valves on ventilation, air conditioning, district heating and refrigeration plants. Functions Function Description Type 3-position control A 3-position signal controls the actuator via connection terminals Y1 or Y2. The desired position is transmitted to the valve. Modulating control The modulating positioning signal provides stepless motor control.

Notes Safety CAUTION National safety regulations Failure to comply with national safety regulations may result in personal injury and property damage. ● Observe national provisions and comply with the appropriate safety regulations. WARNING Risk of burns from hot actuator brackets The actuator brackets on heating plants can also become hot from the contact with the hot valve during operation. The temperature of the actuator bracket can reach 100 °C.
Mounting Mounting positions Indoor application Outdoor application 1) 2) 1) Only together with weather shield ASK39.2. IP54 housing protection remains unchanged. 2) SAY61P../MO is not intended for outdoor use. 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 R Flow speed Positioning signal Y DC 0...10 V, 4.
