The direct-acting proportional directional spool valve type EDL by HAWE Hydraulik enables precise and sensitive control of hydraulic consumers. Designed for mobile hydraulics, the directional valve can be seamlessly combined with the PSL 2 type valve sections thanks to its modular system and is rated for operating pressures up to 320 bar. Technical Data: Maximum operating pressure: 320 bar (ports P, A, B, LS, M, Y) Maximum flow rate (consumer): up to 48 l/min (maximum return flow rate must not exceed 80 l/min) Actuation type: Direct-acting System integration: Flexibly bankable and combinable with the HAWE proportional directional spool valve type PSL 2 Available Versions and Variants: Spool symbols: Available as a standard spool with low return pressure (versions L, F, H) or with a constant return pressure of approx. 20 bar (version J, up to max. 25 l/min) to stabilize cylinders with pulling loads. Actuation types: Electrical actuation for the A and B sides (optionally with or without stroke limitation) or as single-sided actuation (only A or only B side). Optionally available with integrated manual override. Pressure compensator (2-way compensator): Equipped with a 2-way compensator as standard. The compensator spring can be selected as a standard version (approx. 6 bar) or a reinforced version (approx. 13 bar). Additional functions (LS limitation): Optionally expandable with an LS pressure limitation that allows a common pressure setting for the A and B sides (setting range 50 to 320 bar), or with an X port for an external pilot valve.

The direct-acting valve bank type CWS by HAWE Hydraulik offers an extremely compact and lightweight solution for controlling the direction and speed of hydraulic consumers. Thanks to the flexible bankable design (modular system), up to 10 directional valve sections can be combined in a single control block. The system is primarily designed for demanding tasks in mobile hydraulics (e.g., municipal vehicles, construction machinery, material handling equipment), but can also be directly mounted to compact hydraulic power packs in stationary hydraulics to save space. Technical Data: Maximum operating pressure: 315 bar (for steel versions) or 210 bar (for aluminum versions) Maximum flow rate: up to 80 l/min at the connection block (the switching flow rates of the individual valve sections are designed for 10, 20, 30, or 40 l/min depending on the version) Design: Valve bank in a bankable design with up to 10 sections Materials: Valves made of steel/cast iron (Zn-Ni coated) for maximum pressures or aluminum for weight-optimized applications Structure and Versions of the Modular System: Connection blocks: Flexibly configurable, optionally equipped with an integrated pressure relief valve (standard or for increased return pressure up to 200 bar) as well as with various bypass valves (normally open or closed). Directional valve sections: Available as 4/3-, 4/2-, or 3/3-way spool valves. The sections can be supplied with integrated threads for direct piping or with a flange surface for mounting auxiliary blocks. Additional functions (flange blocks): The flange valve sections can be expanded as needed with important functions, including pilot-operated check valves, throttle check valves, shock and suction valves, or load holding valves. Actuation types: Control is standardly provided via electrical black-and-white actuation or electro-proportional. Both variants are available with manual override. Alternatively, purely manual actuation via hand lever is possible. You can send us an inquiry using the shopping cart function.

The direct-acting directional spool valve type CWL by HAWE Hydraulik offers a compact and cost-effective solution for controlling the direction and speed of hydraulic consumers. As a load-sensing valve without individual pressure compensators, the CWL type features an integrated LS port. Thanks to the flexible bankable design (modular system), up to 10 directional valve sections can be combined in a single control block. The system is specifically designed for mobile hydraulics and is ideal for municipal vehicles, agricultural and forestry machinery, as well as aerial work platforms. Technical Data: Maximum operating pressure: 315 bar Maximum flow rate: 60 l/min (at the connection block) Design: Valve bank in bankable design with up to 10 sections Application areas: Demanding tasks in mobile hydraulics (construction machinery, cranes, municipal technology) Structure and Versions of the Modular System: Connection blocks: Configurable for open-center systems (fixed displacement pumps) or closed-center systems (variable displacement pumps). Optionally with an integrated pressure relief valve for protection. Directional valve sections: Available with various spool symbols. The inlet edges of the spools can be selected for different nominal flow rates (10, 20, 30, or 40 l/min). Additional functions (flange blocks): The valve sections can be flexibly expanded with flange blocks to include pilot-operated check valves, throttle check valves, or shock and suction valves. Actuation types: Control is available either as black-and-white or electro-proportional. Both versions can be optionally equipped with a manual override. Alternatively, purely manual actuation via hand lever is possible. You can send us an inquiry using the shopping cart function.
