Features:

Small size; exquisite type; zero-pressure start, switch quickly, sealing; authoritarian coil, easily destroyed; suitable for small-caliber, low pressure piping systems.

working principle

NC: When the coil is energized, the electromagnet core pull, pressure relief hole to open the main piston driven by the medium pressure, open the main valve port, media circulation. When the coil power, turn off the main valve port, media cutoff.
Normally open: When the coil is energized, the electromagnet core pull, pressure relief hole is closed, the main piston driven by the medium pressure, close the main valve port, media cutoff. When the coil power, open the main valve port, media circulation.
