brief introduction
This series of products is a direct two-position two-way solenoid valve, which has two-way function, that is, both ends of the solenoid valve can be used as the inlet of the medium, the medium can flow forward and backward, and the valve also has the function of automatic check. The design and identification of solenoid valves conform to RCC-E, IEEE323, IEEE344, IEEE382, EJ/T and GB3836 standards. They are suitable for connecting or blocking control pipeline media in nuclear power plants and nuclear chemical industry with nuclear safety level requirements or in explosion-proof environments.
main features
1. direct acting structure, zero pressure difference can be opened and closed normally, and the action reliability is high.
2. according to the requirements, it can be equipped with manual devices, and can be operated manually under special conditions such as power failure and maintenance.
3. for vacuum applications, the vacuum can reach 1.33X10-7MPa.
4. the pressure balance technology can be used to seal the positive and negative directions in two directions.
5. all rubber parts can be used under high radioactive and temperature sudden environmental conditions.
6. High insulation level and high protection level: The insulation level of coil is H level, and can meet the application of LOCA environment.
7. meet seismic applications.
8. it can be designed and manufactured to be flameproof, and can be used in explosive environment.
