Direct-acting bistable solenoid valve uses dynamic current to realize state change. It has the function of maintaining the original closed point for a long time without external signal.
Compared with the existing standard for monostable solenoid valves (which can be called monostable solenoid valves), this standard not only eliminates the distinction between normally open and normally closed types, but also eliminates the provisions of the maximum valve stop difference, the minimum valve difference, and the allowable change of the rated voltage. This standard has been adjusted and the maximum age of the solenoid valve has been added.
This standard was proposed and approved by the Technical Committee for Standardization of Refrigeration Equipment of the Ministry of Machinery Industry, and the drafting unit of this standard is Zhuhai Bada Electromechanical Co., Ltd. This standard is the first and last edition.

Dynamic bistable solenoid valve for refrigeration system B/In539
This standard covers the type test, basic warning numbers, technical requirements, test methods, control rules and markings of electromagnetic valves (hereinafter referred to as electric valves), and can also be used for flow control devices such as flow regulating devices.
