The cartridge type solenoid operated normally closed
valves are normally closed solenoid valve, when the loss of power to prevent the flow of oil from port 2 to port 1. When the solenoid valve is energized, the electromagnetic force to lift the pilot valve from the valve seat, the main spool to generate a pressure differential, thereby, providing a force to lift the main valve from the valve seat.
As the cartridge type solenoid operated normally closed valve with a function in the same power can be obtained from port 1 to port 2 as a low-pressure low-flow one-way valve; when pressure is applied to one, the standard model has a throttle connected to the two.
The technical information of cartridge solenoid valve :
Max. operating pressure:350bar
Rated flow capacity: 13.2 L/MIN
Internal leakage: ≤5 drops/ min. at pressure of 350bar
Recommended filtration: 25 MICRON
Hydraulic fluids: Mineral Oil, Viscosity 10 - 400 cST
