RE 64638/07.2017, Bosch Rexroth AG
Features
▶ Temperature proportional pressure adjustment by
thermostat
▶ Compact design
▶ Energy saving
▶ Very high repetition accuracy
▶ Type of actuation:
hydraulic, electric
▶ With spring return
Functional description
The 6/2-way valves are hydraulically or electrically actuated
directional spool valves.
They control the starting, stopping and direction of a flow.
In general, these valves are used as an extension to a
mobile control block instead of fitting an extra section.
The following overview table shows the models available.
▶ Direct or pilot operated 6/2-way directional valves
▶ Sizes 6, 20, 30
▶ Series 2X
▶ Maximum working pressure 350 bar
▶ Maximum flow 450 l/min
Multi-way directional valves (hydraulic switches)
