DAMPER & VALVE MOTOR ACTUATORS Type EGK & WGKGENERAL DESCRIPTION•Series GK motor actuator can provide On-Off, propor-tional or floating control of damper, valve or other con-trolling devices.•Balancing relay without contact causes no burn-out.•Type EGK is for damper. Type WGK is for valve.Power requirement: 24V.AC ±10%, 50/60HzMax. power consumption: 21VA (without spring return action) 24VA (with spring return action)Input signal:resistance0 to 135ΩCurrent 4 to 20mA. DC (Input Impedance 250Ω)Voltage 1 to 5V. DC (Input Impedance 100kΩ)Type: EGKTorque: 12.2N·m {1.25 kg·m} (without spring return action) 3.9N·m {0.4 kg·m} (with spring return action) Rotation angle:90 to 270° (without spring return action) 90 to 160° (with spring return action) Delivery Setting 90°Timing: 80 sec/160° Ambient temp.:−20 to 55°C (without spring return action) −10 to 55°C (with spring return action)Weight:4.3kg (without spring return action) 6.1kg (with spring return action)Type: WGKThrust:1220N {125 kgf} (without spring return action) 390N {40 kgf} (with spring return action)Stroke:14 to 50mm (without spring return action) 14 to 30mm (with spring return action) Delivery Setting 20mmTiming: 80 sec/stroke 25mm Ambient temp.:−20 to 55°C (without spring return action) −10 to 55°C (with spring return action)Weight: 5kg (without spring return action) 6.7kg (with spring return action)Type EGKType WGKDAMPER MOTOR SELECTION*1. The motor actuates with On-Off or floating signal from sensor. *2. The motor actuates with proportional signal from electronic sensor (Example: Type RBE Control Unit). *3. The motor actuates with the signal between 0 and 135Ω from electric sensor (Example: Type PWS Thermostat). *4. Spring Return Type is so designed that actuator shaft returns to safe side on current failure.・Auxiliary potentiometer is to provide the signal between 0 and 135Ω in accordance with motor angular rotation for output.・Auxiliary switch provides the contact signal of S.P.D.T. for output.・Enclosure: IP62VALVE MOTOR SELECTIONTYPE NUMBER SELECTION (SPECIFICATIONS)FunctionModelOn-Off / Floating ControlWithout Positioning Balance RelayWith Positioning Balance RelayWith Positioning Balance RelayOn-Off / FloatingOn-Off ServoResistance Input Current InputVoltage InputStandardWGK–N500AWGK–N600 A/SWGK–N700 A/SWGK–N701 A/SWGK–N702 A/SWith Auxiliary Potentiometer−WGK–N610 A/SWGK–N710 A/SWGK–N711 A/SWGK–N712 A/SWith Auxiliary SwitchWGK–N520AWGK–N620 A/SWGK–N720 A/SWGK–N721 A/SWGK–N722 A/SFunctionModelOn-Off / Floating ControlWithout Positioning Balance RelayWith Positioning Balance RelayWith Positioning Balance RelayOn-Off / FloatingOn-Off ServoResistance Input Current InputVoltage InputStandardEGK–N500AEGK–N600 A/SEGK–N700 A/SEGK–N701 A/SEGK–N702 A/SWith Auxiliary Potentiometer−EGK–N610 A/SEGK–N710 A/SEGK–N711 A/SEGK–N712 A/SWith Auxiliary SwitchEGK–N520AEGK–N620 A/SEGK–N720 A/SEGK–N721 A/SEGK–N722 A/S*4*3*2*1*2*3*4*1
