How a 2-way slip-in cartridge valve works


Function of the revised C_ENxx valve series

The 2-way slip-in cartridge valves are inserted in the control block into a bore standardised according to ISO 7368 and closed with a control cover. In operation, they merely act as amplifiers, following the pilot valve on the cover that can be controlled manually or electrically via an analogue or digital interface. Combined with intelligent electronics, complex hydraulic circuits that are characterised by very high pressures and flows can thus be implemented within a hydraulic block. The proven range of 2-way slip-in cartridge valves has been supplemented with significantly more powerful valves in the nominal sizes NG16, NG25, NG32, NG40 and NG50. The new

series is characterised by a three-part construction and, thanks to optimised flow geometry, offers practically a doubling of the maximum possible flow rate, while still maintaining a very low pressure drop ∆p. The slip-in cartridge valves have also been given a higher pressure resistance and are now approved for operation up to a system pressure of 630 bar (9,000 psi). Due to these two aspects, it is now possible to plan hydraulic systems much smaller. This means that, compared to conventional valves, the next smaller valve can now be used without compromising performance. This leads to even lighter, more compact and efficient hydraulic systems.
