brief introduction
This series of products is direct acting two position three way solenoid valve with internal thread connection. The design and appraisal of solenoid valves conform to RCC-E, IEEE323, IEEE344, IEEE382 and EJ/T standards. They are suitable for the pneumatic or hydraulic control pipeline systems with nuclear safety requirements in nuclear power plants and nuclear chemical industry to control the connection, reversal and distribution of pipeline media. This kind of solenoid valve is also called the instrument solenoid valve in the industry.
main features
1. direct acting structure, zero pressure difference can be opened and closed normally, and the action reliability is high.
2. with manual device, manual operation can be realized under special conditions such as power failure and maintenance.
3. for vacuum applications, the vacuum can reach 1.33X10-7MPa.
4. all rubber parts can be used under high radioactive and temperature sudden environmental conditions.
5. High insulation level and high protection level: The insulation level of coil is H, and can meet the application of LOCA environment.
6. meet seismic applications.
7. it can be designed and manufactured to be flameproof, and can be used in explosive environment.
