      Application

      B11MN-2W diaphragm solenoid valve is widely used in petrochemical,electric power, machinery, medical, scientific research, filling, building, .industrial kiln, pipeline medium automatic control and other fields.

      Features

      Zero pressure start, low pressure combination; The structure and .performance of the piston are stable. Autocratic coil, not easy toburn; It is suitable for low pressure andlarge caliber pipeline system.

      Principle

      It is a principle of combination of direct-acting and doublepulling. When there is no pressure difference between the inlet and .outlet, the electromagnetic force directly lifts the valve corediaphragm upward and opens the valve port. After the power is cutoff, the magnetic valve core closes the valve port under the urgingof spring force and medium pressure to cut off the fluid medium.Check function: the outlet pressure is greater than the inletpressure, and the medium will conduct reversely. Check valves orcustom valves with check function can be installed.
