Directional Control Valves Overview
Directional control valves are crucial in hydraulic systems for managing the flow and direction of hydraulic fluid. They can be actuated manually or hydraulically and come in configurations such as 2-way, 3-way, and 4-way types.

Manual Push/Pull Valves
These manually operated valves include models like CP600-1, DMP08-NC, and DMP08-NO. The CP600-1 supports a flow of 68 l/min at 210 bar, while DMP08 models, which are normally closed or open, allow a flow rate of 38 l/min.

Manual Rotary Valves
Models such as CP620-1 and CP630-1 offer 2-position configurations for flow direction control, handling up to 75 l/min at 210 bar.

Hydraulic Piloted Valves
These valves, including CP710-3 and CP712-2, are suited for complex systems, offering higher flow rates like 265 l/min for the CP713-2, and are designed for pressures up to 210 bar.

Applications
Used in high-flow circuits, bypass valves for traction circuits, and proportional flow control circuits. The CP712-7 is notable for pressure-compensated proportional flow control.

Installation and Operation
Installation involves steps like placing a locating pin and securing with a cap and lock nut. Operation is influenced by spring bias and pilot pressure.

Specifications and Ordering Information
Valves have specific specifications such as rated pressure, flow rate, and leakage rates. Ordering includes options for seals, housing, and knob configurations.

Technical Specifications
Valves are rated for 210 bar (3000 psi) and flow rates from 25 l/min to 265 l/min. Available in 2-way and 3-way configurations, with normally open or closed states.

Materials and Seals
Equipped with Buna-N or Viton seals, with maintenance kits available. Spool seals can be configured at various positions.

Housing and Ports
Options include aluminum housings with BSP and SAE port configurations, with part numbers for specific types.

Performance and Operation
Includes theoretical performance data like pressure drop and flow characteristics, designed to operate with hydraulic oil at 154 SUS (33 cSt) at 100°F (38°C).

Ordering Information
Detailed ordering codes specify valve configurations, including seal type, spool configuration, and housing options.

Quick Reference Cartridge Valves Technical Information Directional Control Valves Application Notes Directional valves are either manually or hydraulically actuated spools. Directional control valves Manually-actuated valves are available as 2-way, 3-way, and 4-way valves, and are used either for flow or direction control. Hydraulically-actuated spool valves are available as 2-way (normally-open or normally-closed), 3-way, and 4-way valves, and are used for direction control. These are all 2-position valves that are spring-biased to a neutral position and use 3-10 bar [40-150 psi] hydraulic pressure...
