2NM DC5V Motor Actuator With Gearbox For DN20 Mini Motorized Ball Valve
General Description:
The 5VDC Motor Actuator can drive a shaft in a mini motorized ball valve for control the flow in pipe line. With proper gear reduction ratio and motor, its torque output is from 1.8NM minimally. The larger toqure can be achieved for driving bigger valve: DN15, DN20, DN25, DN32, DN40, DN50. Larger size ball valve can be supplied too. The gearbox of motor actuator is with metal gear, very sturdy design ensures the long service cycles more than 20000 times. Over years, we supplied to many brand water meter factories in China.
Applications: mini motorized ball valve, prepaid water meter, AMR water meter, ultrasonic water meter, heat meter, HVAC, zone valve, heat control valve, etc.
