WEM Electric direction valve is one of my products introduced from LINCOLN(GmbH),applied in the concentrical lubrication system ,to reverse the direction of lubricant flows alternately then to dispart it to line I or II ,at the same time to fill the discharge oil return to the line II or line I into the reservoir.

The action of reverse is achieved from the pushing piston driven by eccentric link,which driven by reduce gear motor.The reversal signal is sent by pressure switch in the terminal of two line lubrication device,or supplied by time relay.After one revesal motion,the eccntric turns 180 °to contact one of the limit switches,and then stops automatically.
