DN50-20P is a type of direct-acting and internally piloted 2/2-way solenoid valve. This type of valve is composed of an electrical solenoid, a pressure regulator and a control head. It is widely applied in industrial automation control systems and designed to control the high/low flow liquid, gas, steam and vacuum of all kinds of subsystems.

In the control system, when electric current runs through the coil, a solenoid core is magnetized. The solenoid core then opens a valve disc, which passes the fluid from the upstream to downstream side. When the power is off, the spring action returns the valve disc to the closed position. As a result, effectuating On/Off operation of the medium.

The electrical solenoid of the DN50-20P is built with the highest quality materials to withstand the toughest environments, together with the plug-in electrical connection to make it easier and more convenient for loop wiring and complete process control as well. Also, it is constructed to work with temperature range up to 50℃ and a maximum operating pressure of 0.3 MPa. Furthermore, all internal surface are treated with electroless nickel plating to insure a longer life.

In terms of application, the DN50-20P is often used in water treatment systems, cooling systems, ventilation systems, irrigation systems, pumps, and HVAC systems. In most applications, it can operate independently as a switch, allowing it to turn on or turn off the supply of media. In addition, it can also work together with other components, such as remote pressure switches, actuators and controllers to form a complete control system.

DN50-20P solenoid valve is capable to operate in a wide range of media, such as air, water, steam and light oil. It is designed with specialized non-rotating stem to resist any side-load stress and a gland packing protected from conducting mechanism, assuring the best leak tightness in the most extreme conditions and applications. It is also equipped with a sensitive control head to allow the mediums with lower pressure to open the valve with minimum actuating pressure, at the same time, allowing a greater flow rate. Therefore, it performs exactly as required even at extreme temperatures, pressures, and competing forces.

Overall, the DN50-20P is an efficient and cost-effective solenoid valve solution, designed to be dependable and precise in even the most extreme conditions. It offers maximum performance with minimum maintenance and can be used in multiple applications to meet the needs of both light and heavy duty applications.
