Electric Motor Actuator With Metal Gearbox for Zone Valve DN20
General description
Our DC Motor Actuators are designed for driving mini motorized ball valve, prepaid water meter, ultrasonic water meter, ultrasonic heat meter. The suitable pipe diameter ranges from DN15 to DN50. The gear ratio: 2000:1 for DN15/20 ball valve, torque output: 1.8NM or above. It is sturdy design, we use brass gear system, so the life cycle is more than 20000 times.
Applications: motorized ball valve, IC card prepaid water meter, ultrasonic water meter, zone valve, heating control valve, HVAC, mini motorized valve.
Technical data-Model K33
