2 port motorized valve
The 2 port motorized valve uses an innovative threaded connection method to firmly combine the driver and the valve. This design allows the driver to be easily installed after the valve is pre-installed, greatly simplifying the on-site operation process. This modular installation method provides flexibility for wiring and layout under different working conditions, facilitating operators to quickly debug and maintain in various environments. The driver adopts a compact flat design, which allows it to be installed against the wall, minimizing the installation space requirements and is very suitable for applications with limited space.

Notes
●During installation, ensure that the valve is firmly connected to the pipeline and check for leaks.
●The wiring of the electric actuator must comply with relevant electrical safety regulations to avoid short circuits or overloads.
●Check the working status of the valve regularly to ensure that there is no blockage or poor operation.
FAQ
1. What factors affect the service life of a 2 port motorized valve?
The service life of a two-way electric valve is affected by many factors, including the material, manufacturing process, working environment, and frequency of use of the valve. Reasonable selection of valve materials and specifications, correct installation and use, and regular maintenance and care can extend the service life of the valve.
2. How to ensure the safety of a 2 port valve under high pressure?
Under high pressure, a two-way electric valve needs to adopt a high-strength valve body and sealing structure to withstand the impact of high-pressure fluids. At the same time, the electric actuator also needs to have sufficient power and stability to ensure that the valve can be opened and closed normally. In addition, protective devices such as safety valves can be installed to prevent danger caused by excessive pressure.
3. What is the impact of the flow characteristics of a two-port electric valve on the system?
The flow characteristics of a two-way electric valve will affect the flow control accuracy and stability of the system. Different flow characteristics (such as linear, equal percentage, fast opening, etc.) are suitable for different system requirements. When selecting a two-way electric valve, it is necessary to make a reasonable choice based on the flow characteristics requirements of the system.
