Motorized Control Valve

Motorized Control Valve

Basic information
Basic information
This valve can automatically adjust the flow rate of pipelines, the water control of air conditioning ventilation equipment, the water control of heating equipment.
Features
Features
1. The actuator is made of the cast aluminum bracket and plastic shell with small volume and light weight;
2. Transmission gear adopts metal gear, which greatly improves the service life of the drive;
3. Low power consumption, high output power, low noise;
4. Suitable for various control signals: increment (floating point), voltage (0-10v), current (4-20ma).
Principle
Principle
The motorized control valve can be used with the thermostat, the motor is controlled by a motorized control valve's actuator, the valve open or close, cold water or hot water pipe make or break, again through the fan coil air supply, so as to realize the automatic temperature adjustment. When you need to work, provided by a thermostat open signal to make the motorized control valve connected to the ac power and action. Open valve, chilled water or hot water into the fan coil units, to provide room air conditioning or heating, when the room temperature reaches the thermostat set point, the thermostat to the motorized control valve, reset spring to close the valve, thus cutting into water fan coil units, through the valve closed and open, make the room temperature always stay in the temperature control setting temperature range.
Installation and Commissioning
Installation and Commissioning
When installing, vertical installation is preferred and sufficient space should be left to repair and remove the drive. The voltage regulator controls the opening stroke by 0-10vdc voltage, and the current regulator controls the opening stroke by 4-20ma current. The actuator is protected and cannot be covered by insulation material to prevent leakage and damage internal parts and motors. For specific use, please consult ZhengFeng Valve Group.
