The fine feed-/fast approach valves are utilised in hydraulic systems, which require an electrically controlled fine feed-/fast approach changeover, such as positioning controls on machine tools or elevation controls of elevating platforms, etc. Due to the sandwich construction, these fine feed-/fast approach valves can be integrated into stacked systems as an intermediate flange.

The fine feed-/fast approach valve serves for the electrically controlled two-stage speed control. Fine feed and fast approach. In the first stage, the fine feed, the volume flow is controlled by the flow control valve, to the manually adjusted value independent on the load. In doing so, the poppet valve is closed. In the second stage, the fast approach, the volume flow, dependent of the load and of the system pressure, flows through the poppet valve.

Sandwich construction offers a compact solution. Hardened working parts ensure a long, reliable and trouble-free life. The cartridge construction gives flexibility in servicing.
