Actuator
WVA4-310   24VAC/DC±15%, proportional (0-10VDC/0-20mA, 2-10VDC/4-20mA)
Output torque: 10N.m                                                                     Angle of rotation: 90°
Manual handle   Automatic overload protection system
Manual selection of ball rotation direction: C.W. /C.C.W, factory setting is C.W.
Protect rank: IP54                                                                          Operation time: 50S-90S

Function (proportional type)
The actuator is controlled by a modulating proportional control signal, using high transmitting ratio gear drive to fix and lock.

WRA4-310   24VAC/DC±15%,  proportional (0-10VDC/0-20mA, 2-10VDC/4-20mA)
Black wire and brown wire are the power wire.
Yellow wire accept 0-10V control signal to control the valve's open angle.
