brief introduction
This product is a direct two-position two-way solenoid valve. Its design and appraisal conform to the standards of R C C-E, I E E 323, I E E 344, IEEE382 and GB3836. It has been successfully applied in the water level control system of mobile hydrogen combiner in PWR nuclear power plant. The product has two-way function, that is, both ends of solenoid valve can be imported as medium, the medium can flow forward and backward. At the same time, the valve also has check function. It is suitable for nuclear power plant and nuclear chemical industry with nuclear safety level control pipeline system or explosion-proof environment to control the connection or interruption of pipeline medium.
main features
1. direct acting structure, zero pressure difference can be opened and closed normally, and the action reliability is high.
2. for vacuum applications, the vacuum can reach 1.33X10-7MPa.
3. the pressure balance technology can be used to seal the positive and negative directions in two directions.
4. all rubber parts can be used under high radioactive and temperature sudden environmental conditions.
5. high insulation class high protection level: coil insulation class is H grade.
6. meet seismic applications.
7. it can be designed and manufactured to be flameproof, and can be used in explosive environment.
