Electric bidirectional actuator with compact dimensions suitable to valves with hot or cool water used in a variety of applications including FCUs, AHUs, zone control systems, solar plants, small heating and cooling plants, small reheating and dehumidification coils. Force is 300N i.e. it provides 50% more force than standard MVT actuators that means higher close-off performances. It is easy to fit the actuator on Controlli valves. Further more, thanks to self-stroking feature and 17mm long stroke, these new MVT 300N actuators can be used to retrofit actuators from other manufacturers, for example actuators for MZX, VZX, MEU, FEU, VEU Satchwell valves. Additionally, they can be used to motorize a number of PICVs available in the market.
    MVT 300N actuators can be controlled by either proportional (modulating) signals or by an increase/decrease (floating) signal. On all models, PC Board is equipped with two micro-switches detecting the complete open and complete closed positions.
    Two versions are available:
SHORT: up to 9mm yoke, self stroking, only pushing
LONG: up to 17mm yoke, self stroking, push & pull
    Timing:
60seconds on 5,5 mm stroke valves e.g. VMBT
90seconds on 8,5 mm stroke valves e.g. 2TGA..B
    IP43 protection class.
    Manual override by means of a 3mm
    Allen key.
    Proportional actuators can be connected to any controller with 0..10Vdc, 2..10Vdc, 0..5Vdc, 6..10Vdc, 4..20mA signal.
    Feedback signal: 2..10Vdc (2V=fully retracted; 10V= fully extended)
    Proportional actuators are equipped with 3 LEDs visible under the cover
• Green for Power On
• Yellow for opening action
• Red for closing action
    Direct / reverse action: actuator movement direction can be selected via a dip-switch.
