APR40405 - Valve actuator 0-10 V (NC)
Valve actuator APR4045 is intended for modulating operation of valves. The actuator is mounted with the aid of an adapter ring that enables problem-free installation of the various adjustment and mixing valves that are available on the market.
Function
The 0-10 VDC control signal is pulsed to a proportional 0-4 mm movement (stroke length). The actuator only reacts to control signals over 1 VDC so as to ignore any interference and hum voltage.
The valve actuator is equipped with function indication. The projecting extension on the top shows how much the actuator is activated (open).
Radiator valve APR40405 is normally closed when the power is off.
