Refrigeration solenoid valve is an automatic basic component used to control the direction of fluid, suitable for no pressure difference or low pressure system, such as pressure lower than 0.8MPa, temperature not higher than 180 ℃ various mixed media pipelines, such as papermaking, printing and dyeing, Clothing equipment, HVAC, electroplating coating, drying equipment, mechanical equipment and air treatment industries are the preferred products for automation control engineering, project transformation and equipment matching.

Features:

1. The recoil type special structure which integrates direct-action valve opening and pilot-operated valve opening;

2. Zero pressure can also open the main valve, low pressure difference, large flow rate, wide application range;

3. Different mediums are used, and the targeted sealing is adopted to further improve the rationality of the solenoid valve;

4. The valve plug adopts a one-time molding process, which further improves the life and reliability of the solenoid valve;

5. Adopting precision cast copper body, the appearance is exquisite and beautiful.

Structural features:

Electromagnetic step-by-step direct piston operation structure

①Recoil-type special structure that integrates direct-acting valve opening and differential valve opening;

②The main valve can be opened even without pressure, and the flow rate is large under low pressure difference, and the application range is wide;

③ Sealed with polytetrafluoroethylene, good temperature resistance;

④Reliable action with zero pressure difference;

⑤Type: normally closed.

The solenoid valve is completed by using electromagnetic force to act on the iron core sealed in the magnetic isolation sleeve of the electric control valve. There is no dynamic seal, so the leakage is easy to be blocked. The torque control of the electric valve is not easy, and it is easy to cause internal leakage, or even break the head of the valve stem; the structure of the solenoid valve is easy to control the internal leakage until it is reduced to zero. Therefore, the solenoid valve is particularly safe to use, especially suitable for corrosive, toxic or high and low temperature media. The solenoid valve itself has a simple structure and low price, and is easier to install and maintain than other types of actuators such as regulating valves. What's more remarkable is that the composed automatic control system is much simpler and the price is much lower. Since the solenoid valve is controlled by a switch signal, it is very convenient to connect with the industrial computer. In today's era when computers are popular and prices have dropped sharply, the advantages of solenoid valves are even more obvious.
