WEH10,16,25,32 Hydraulic Directional Control Valve

WEH10,16,25,32 Hydraulic Directional Control Valve
Product Details

Hydraulic directional control valve of WEH series is an electro hydraulically directional operated valve is the union with 4WE6 directional hydraulic solenoid valveand large flow rate of hydraulic directional spool valve. The 4WE6 directional hydraulic solenoid valve uses for controlling the spool direction of the WH base. The advantage of electro hydraulically directional operated valve is much convenient operation control with high pressure and large flow rate.

Finotek manufactures the WEH series is separated production and tested, first test the WE6 and WH separately, then the WEH unit should be tested again, it is eliminate the leakage between the WE and WH installation gap and the valve inner leakage must passed to guarantee its working reliability.

INTERNAL & EXTERNAL SUPPLY CONVERSION
External supply: Remove the valve cover, convert the pin smaller head towards to main valve.
Internal supply: Rated the pin 180 degree, when the pin smaller head in opposite direction of external supply. 

INTERNAL & EXTERNAL DRAIN CONVERSION
External drain: Remove the nut (On “1” location) and screw in the M6 plug
Internal: Screw out the M6 plug
