brief introduction
This series of products is a pilot type two position four way solenoid valve. It has compact and reasonable design structure, excellent and durable materials, flexible and reliable movement, long service life, large circulation capacity, convenient replacement and maintenance, and fast. The design and appraisal of the product conform to RCC-E, IEEE323, IEEE344, IEEE382, EJ/T standards. 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 level requirements, and for the control of the connection, direction change and distribution of pipeline media. This kind of solenoid valve is also called the instrument solenoid valve in the industry.
