How it works:
Normally Closed: When the solenoid coil is energized, the electromagnetic force open the pilot hole. The pressure chamber on the rapid decline in the vicinity of the piston and seals on the formation of a high pressure low. This pressure difference push the piston and seals from the valve seat on the lift. Valve opening; coil energized, the spring force pilot hole closed, the bypass valve inlet pressure into the hole on the chamber quickly, in the vicinity of the piston and seals compete on the formation of a low pressure difference, thus promoting the piston and seals pressing down on the seat, the valve closes.
Normally open type: normally closed operation with the opposite direction.

Overall structure:

Selection guide:
1.Fluid medium pressure, temperature and other parameters must be provided according to the actual working conditions.
2.If the fluid contains impurities, the solenoid valve should be installed in front of the filter (filter ≥ 60 mesh), and the fluid should be no solidification or crystallization.
3.Or more dimensions may vary due to customer technical parameters change, please prevail in kind。
