MECHANICAL SWITCH VALVE DU1-GKS

Lincoln mechanical switch valve with indicator pin and limit switch model DU1-GKS

Designed for use in two-line lubrication systems with a maximum working pressure of up to 350bar.

The operating principle is similar to that of a 4/2 valve.

With an active pump at port P, port A will be pressurized up to the maximum set switching pressure. Line B will relieve pressure through port R into the reservoir of the pump. Upon reaching the maximum set pressure, the valve switches to port B, and port A relieves via R into the reservoir of the pump.

Switching pressure adjustable between 140-350bar
