brief introduction
This series of products is a pilot type two-position three-way solenoid valve. Its design and appraisal conform to RCC-E, IEEE323, IEEE344, IEEE382, EJ/T standards. The drive of the product is controlled by double coils, and the pipe connectors are connected by internal threads. It is suitable for the pneumatic or hydraulic control pipeline system with nuclear safety requirements in nuclear power plants and nuclear chemical industry to control the connection, commutation and distribution of pipeline media. This kind of solenoid valve is also called the instrument solenoid valve in the industry.
main features
