Directional Control Valves

Hydraulic Applications

Any industry that relies on hydraulic circuits, machinery and equipment across a vast selection of applications will use hydraulic directional control valves.

Bosch Rexroth DCVs feature prominently in the automotive industry in every vehicle transmission type. They are used in automatic transmissions (AT), automated manual transmissions (AMT), continuous variable automatic transmissions (CVT), double-clutch transmissions (DCT) and the control of automated clutch actuations in hybrid drives.

Other applications that make use of Bosch Rexroth DCVs in hydraulic applications include machine tooling, primary metals, pulp and paper, die-casting and foundry, wood processing, turbine control, and test equipment and simulation.

Pneumatic Applications

Compressed air is applied to operate tools and equipment in numerous industrial applications from diesel engines to pneumatically operated power tools to the medical industry.

Aventics 2-way valves facilitate air use in applications like shop air, airlines, supplying pressure to systems and power air tools and motors.

They are ideal for use with safety applications that require a cooling flow. In a tapped exhaust ports, the air exhausted from cylinder retraction can be used for secondary purposes such as cleaning or ejecting parts and operating industrial vibrators.

In the medical industry, an Aventics directional control valve is used in systems or machines like those for sample testing and cleaning instruments, for example.
