Solenoid spool valve WDG10 are design the way of solenoid with central solenoid connection through a square box. The valve control the hydraulic flow direction, start to flow or stop flow. The WDG series are improve to be better performance with characteristic of more reliable and lower noise of spool switching, since the sliding spool are optimized to large flow.

The coils of solenoid spool valve can be replaced or even change the different voltage of coils while it is in working position, there are manual override of the coils in case the valve spool stuck in certain place and can be fixed easily by pushing.

Solenoid spool valve FINOTEK produced is focus on the key parts of solenoids and spools, the spools mostly effects the valve performance, like valve leakage and function of switching, we use professional spool grinding machines to produce high precise spools, which help our valve to achieve lower pressure drop and longer working life.

Valve Ordering Code

Example (Normal code): “FT-WDG 10 E 6X/ DC24 T ” Explanation As Below:

FT- WDG 10 E   6X / DC24 T  
(1) (2) (3) (4) (5) (6) (7) (8) (9) (10)

(1) Producer code= FT
(2) WDG= Power Central Connection valve
(3) Size= 10
(4) Spool symbol= E,F,H, please see the spool symbol below
(5) No code= Double coils
  A= Coil at side A
  B= Coil at side B
(6) Valve series
(7) No code= With spring return
  O= Without spring return
  F= Without spring return with detent

(8) DC24= DC voltage 24V 
  DC12= DC voltage 12V 
  AC220= AC voltage 220~230V 50/60 Hz
  AC110= AC voltage 110V 50/60 Hz
(9) T= Central connection box
(10)No code= Round chrome plated steel coil(s)
  L5= Round black bakelite coil(s)
