Screw-in Cartridges Screw-in Cartridges

Screw-in Cartridges of the CL04 valve series

CL04 Cartridges The valves in the CL04 valve series are screw-in cartridges for a maximum operating pressure of 350 bar. Despite their high switching performance of up to 50 l/min, all electrically actuated valves are directly controlled, making them particularly robust and ideal for mobile hydraulic applications. All spools, poppets and sleeves are hardened and all external parts are protected against corrosion. To ensure that the cartridges can always be relied upon to operate correctly even under rough conditions, we have subjected them to a stringent validation process during development. In order to maintain this standard in future, each individual valve is fully automatically tested during serial assembly.

Directional ValvesHigh-performance poppet type valves in both 2/2 directional and 3/2 directional versions – with negative or positive overlap – form the basis for the series. These are supplemented by switching and proportional cartridges in a spool design. The proportional 2/2 directional poppet valve designed for small flow rates holds a special position.

Pressure ValvesPressure relief and mechanical/electrical proportional pressure control valves for different pressure ranges.

Flow control ValvesHigh pressure resistant flow control valves are available in two sizes, set to a fixed volume flow.

Check ValveCheck valves, direct and pilot operated, with hardened spools are available with different opening pressures, as well as for different flow rates.

3/2 directional valve, poppet type positive / negative overlap

The high-performance 3/2 directional valves have hardened poppets and sleeves. All external parts have a Cr VI-free zinc coating and thus they are also suitable for use under rough environmental conditions. In functional terms, the positiv overlapped version is particularly suitable for use in constant pressure systems because of the lack of pressure shocks in switching operations. Both versions are resistant to silting over long periods under pressure.

De-energized the valve is kept open by a spring, allowing flow from 1 to 2 or wise versa. This functionality is required in safety-related applications in which it is necessary to switch to a safe, i.e. depressurized, state in the event of a fault. Resistance to silting and the robust direct operated poppet makes the cartridge suitable for such applications. Like all CL04 solenoid cartridges, the poppets and sleeves are hardened and grinded. All external parts have a Cr VI-free zinc coating and thus are suitable for use under rough environmental conditions.

3/2 directional valve, spool type

The 3/2 directional spool valve has hardened spools and sleeves. It can be used wherever zero leakage and maximum switching power of the CL04 3/2 directional poppet valve are not required, but rather a more compact, more energy-saving solution is needed. All CL04 3/2-directional valves require the same cavity. This means that we can offer you a custom tailored solution, while still having the option of replacing the cartridges to fulfil changing requirements without changing the block design.

2/2 directional valve, poppet typeproportional, normally closed

The proportional 2/2 directional poppet valve holds a special position within the CL04 valve series. Requiring the same installation space as the 2/2 directional poppet valve, it enables the regulation of small flow rates in both flow directions and to hold loads securely and without leakage when it is de-energized. All of this is combined with a robust direct actuation as well as hardened poppets and sleeves. The external parts have a Cr VI-free zinc coating. Currently this proportional cartridge is only available for a nominal flow rate of 3l/min, based on a pressure difference of 100 bar. However, other nominal flows can be realized on request.

3/2 directional valve, spool typeproportional

The proportional 3/2 directional spool valves allow the user a smooth and precise handling of loads up to 350 bar, both while lifting and lowering. Due to its spool design the valve is pressure compensated allowing an easy control of varying loads. The valve requires the same cavity as the 3/2-direction seated valves. This means that every CL04 standard valve can be transformed into a proportional valve by simply replacing the cartridge. All of this is combined with a non-sensitive, direct actuation with hardened spools and sleeves. The external parts have a Cr VI-free zinc coating.

Pressure reducing valves DRX, spool typespring loaded

The pressure reducing valves of type DRX are direct acting, spring loaded spool valves. Small moving masses and the direct control make the DRX extremely dynamic – pressure peaks in the hydraulic system are safely balanced. With a nominal flow rate of 25 l/min, they use a high-pressure circuit of up to 350 bar to feed a low-pressure circuit for small motors or the pilot valves of a large mobile hydraulic block. Different internal area ratios allow two pressure levels.

Flow conrtol valve SRV / SRX2 way, spool type

The 2 way flow control valves are designed as spring loaded spool valves. SRV and SRX cover different nominal flow rates with the same cavity. Both versions are fully pressure compensated so they are almost independent of the actual pressure drop between inlet and outlet. Different nominal volume flows within a model size are realized by different orifices. Both flow control valves are highly dynamic due to small moving masses and the direct control. For reliable continuous operation, the working parts are hardened. All visible parts have a Cr VI-free coating.

Valve Sections Valve Sections

Valve sections in the CL04 valve series

The coated spheroidal cast iron valve sections of the CL04 series are designed for 4/3 directional, 4/3 directional with piloted double check valve and 2x 3/3 directional functions at operating pressures up to 350 bar. They can be combined to customer-specific valve blocks using the CLAAS-specific so-called “screw-in-screw” principle. Because of the wide variety of directional valves in the CL04 series, we can easily fit each valve section to the individual requirements of your applications in terms of switching characteristics and nominal flow rate. Customer-specific sections as well as inlet sections with free circulation and pressure relief function complete the valve series.

The remarkable compact aluminium valve sections - with two independent 2/2 directional cartridges - are core elements of the CLAAS modular mobile hydraulic system. These valve sections can be combined with one 4/3-way pre-selection valve to replace several 4/3-way valves. The aluminium housing limits the maximum operating pressure to 210 bar.



Valve sections4/3 directional

The spheroidal cast iron 4/3 directional valve section has a galvanic corrosion protection. Depending on the assembled cartridges, it can be used as a switching valve as well as a proportional valve. All P and T ports are threaded according to DIN EN ISO 6149-1, so that no inlet or end sections are required. As an alternative, it is always possible to flange this valve with other valve sections. This only requires four special screws and two O-rings.

Valve sections2 x 3/3 directional valve section

The spheroidal cast iron 4/3 directional section valve has a galvanic corrosion protection. Depending on the assembled cartridge, it can be used as an on-off valve as well as a proportional valve. This valve is suitable for safety-related functions, for example, in which a 4/3 directional function needs to be brought to a failsafe state. The cartridge based design means that two conventional 3/3 directional valve sections can be substituted by one. All P and T ports are threaded according to DIN EN ISO 6149-1, so that no inlet or end sections are required. As an alternative, it is always possible to flange this valve with others valve sections. This only requires four special screws and two O-rings.

Inlet sectionFree circulation valve with pressure relief function

The spheroidal cast iron housing has a galvanic corrosion protection. It is intended as an inlet section for CL04 valve blocks used in constant flow systems. The direct actuated spool type circulation valve is designed for large flow rates up to 70l/min. Low pressure losses in circulation mode and the integrated pressure relieve function -using a CL04- DBX- make this an efficient and safe solution for your applications in mobile hydraulics. The solenoid of the free circulation valve has a manual override as standard.

CL04 cavityCL04 flange concept Fasteners and seals

All CL04 section valves can be connected in a flange configuration according to the “scew-in-scew” principle using four special screws. The screws have an M8 threat in the screw head and allow valve sections to be added at a later point without having to untighten screws and to fit other longer or shorter screws. Our OEM customers can thus still respond flexibly to customer demands for special equipment in final assembly. The usual installation method using stud screws is still possible, irrespective of this concept.

The modular mobile hydraulic system is characterised by the combination of different valve series in a single valve block:

■ CL06 proportional valves ■ CL04 and CL02 directional cartridge valves ■ ND50 low pressure valves

The sectional valves are flanged to a central inlet section, e.g. CL06 on the left side and CL04 on the right side. Special adapters also enable various valve series to be connected together directly. The possibility of connecting individual valve sections means that all customer-specific functions can be realised in just one valve block.

Modular mobile hydraulic system – Individual control block

Up to 8 valve sections from one series or, if combined with special adapters, from different series can be flanged together.
