Fast approaches / fine feed valve sandwich construction
Description
Feed unit in sandwich construction. In fine feed, the volume flow is controlled independently of the load via the 2-way flow control cartridge to the manually set value. In doing so, the 2/2-way seat valve cartridge is closed. At the fast approach the volume flow, dependent of the load and of the system pressure, flows through the poppet valve.
Application
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.
