SV08-21 Cartridge solenoid valve mounted on the normally open solenoid valve is fastened by a nut (It usually call coil, is an independent part), therefore, the voltage and different shape of solenoid is available to be changed as per requirement. Finotek manufactures the mechanical parts and purchases the coils from reliable suppliers, all of electric coil is tested strictly before delivering to us, coil operation performance should be confirmed again while testing valves.

Normally open SV08-21 cartridge solenoid valve is two flow way and two of valve poppet position cartridge type solenoid operated valve. The hydraulic oil is free to flow through the valve channel when the solenoid is de-energized. Normally open solenoid valve closes fluid flow in one way direction while the solenoid is energized, there is a leakage when the valve  in a closed position because of poppet type, but it is qualified when the leakage is less than 80mL/min at the pressure of 25Mpa (3625PSI).
