| Introduction |
2 way electric water valve normally open is an important execution unit in the field of industrial automation control, which is usually used with a temperature controller to realize automatic temperature regulation. It can adjust the flow of cold water, hot water, steam, and other media according to the requirements of the controller to control the temperature, humidity, and pressure. It is often used in the automatic control of air-conditioning, refrigeration, heating, and other systems. It is connected by an internal thread, and its sealing performance is very reliable under various temperature ranges.
Features
2 Way electric water valve normally open is widely used in the pipeline system of domestic chemical equipment, such as water plants, steam pipelines, chemical equipment, etc., to cut off the circulation of water, oil, gas, and other substances. Its power consumption is low, but it can achieve the purpose of saving water and energy. Its maximum diameter is 2 inches, so a large flow can be achieved. The copper coil has high strength and durability, so its service life is longer. High-quality stainless steel armature is not easy to rust. In addition, our products have a variety of specifications, and we can also provide models with explosion-proof functions according to needs.

| The installation precautions : |
1) First of all, it is necessary to ensure that the interior and pipeline of 2 way electric water valve normally open are clean before installation. The pipeline can be cleaned, and a filter needs to be installed on the valve.
2) The second is the installation direction of the normally open solenoid valve. First, the arrow material on the valve body represents the flow direction of the medium. Second, most solenoid valve products can only be installed vertically. If the working environment and space are limited, you can choose Solenoid valve products that can be installed arbitrarily.
3)It is necessary to install a bracket for the pipeline of the normally open solenoid valve to fix the solenoid valve and the pipeline to avoid the failure of the solenoid valve caused by long-term vibration.
4) Pressure gauges are installed on the front and rear pipelines of the normally open solenoid valve to monitor the working state of the normally open solenoid valve at any time.
5) A bypass setting should be installed for the normally open solenoid valve to facilitate maintenance and daily cleaning when the normally open solenoid valve fails.
6) After the normally open solenoid valve is installed, it is necessary to conduct an action test, and it can be officially put into work after it is correct.
