brief introduction
This series of products is a pilot two-position four-way solenoid valve. Its design and appraisal conform to RCC-E, IEEE323, IEEE344, IEEE382, EJ/T standards. The product is driven by double coils and connected by internal threads. The product is suitable for the control of double-acting pneumatic actuator in the pneumatic or hydraulic control pipeline system of nuclear power plant and nuclear chemical industry with nuclear safety requirements, and for the control of 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. double electric control structure, flexible and reliable action.
2. built in pilot structure, no exhaust in working process.
3. with manual device, manual operation can be realized under special conditions such as power failure and maintenance.
4. unique sealing system and sealing structure, good sealing performance and long service life.
5. all rubber parts can be used under high radioactive and temperature sudden environmental conditions.
