2 way motorized valve
2 way motorized valve is designed for pipe control of central air conditioning and heating systems. It can accurately open or close the pipe to effectively adjust the indoor temperature. The control valve is strongly driven by a one-way hysteresis synchronous motor and is equipped with a reliable spring return device. When the valve is not in operation, it is normally closed. When the driver receives the valve opening signal from the thermostat, it immediately turns on the power and quickly starts the valve, causing cold water or hot water to flow smoothly into the fan coil to provide cooling or heating functions for the room. Once the room temperature reaches the set value, the thermostat will decisively cut off the power supply. At this time, the spring return will play a role, closing the valve and preventing the water from continuing to enter the fan coil. With the effective control of the opening and closing of the valve, the entire system can stably maintain the room temperature within the set range.

FAQ
1. What are the special requirements for the valve core material of the 2 way motorized valve?
The valve core material of the two-way electric valve usually needs to have the characteristics of wear resistance and corrosion resistance. Common valve core materials include stainless steel, copper alloy, etc. In special cases, materials such as engineering plastics or ceramics may also be used to meet the requirements of different fluid media and working environments.
2. How to waterproof the electric actuator of the two-way electric valve?
The electric actuator of the two-way electric valve can be waterproofed by means of sealants, waterproof shells, etc. Some high-end electric actuators may also use special waterproof coatings or sealing structures to ensure normal operation in humid or underwater environments.
3. How to ensure normal operation of the two way motorized valve at extremely low temperatures?
At extremely low temperatures, the two-way electric valve can use special insulation materials to wrap the valve body and electric actuator to prevent freezing and damage. At the same time, select sealing materials and lubricants suitable for low-temperature environments to ensure the flexibility and sealing of the valve.
