2/2 Solenoid Cartridge Valve, Size 6

Transcription

1 / Solenoid Cartridge Valve, Size 6 Q max = l/min, p max = 35 bar Bidirectional seat-valve shut-off, direct acting De-energised closed Guided valve spool and poppet Available in two mounting versions With or without manual override Hand lever can be fitted on solenoid All exposed parts with zinc-nickel plating High pressure wet-armature solenoids The slip-on coil can be rotated, and it can be replaced without opening the hydraulic envelope Can be fitted in a line-mounting body Description The WC series of / solenoid operated directional seat valves are size 6, direct acting, pressure balanced, push-in cartridges. In the normal condition (de-energised closed), flow is shut off without leakage. The core element operates on the tried and tested principle of the guided poppet, and the guide spool has a seal. Two different mounting versions are available, which allows the designer to choose the insertion depth (flange. mm or 8 mm). These cartridge seat valves are also available with or without manual override, and with the option of an additional hand lever. These valves are predominantly used in certain mobile and industrial applications where leak-tight shut-off functions are crucially important. Examples are where loads, tensions, or clamping forces must be held without leakage. All external parts of the cartridge are zinc-nickel plated to DIN and are thus suitable for use in the harshest operating environments. The slip-on coils can be replaced without opening the hydraulic envelope and can be positioned at any angle through 36. If you intend to manufacture your own cavities or are designing a line-mounting installation, please refer to the section Related data sheets. Symbol 3 Technical data A de-energised open function can be created by using the 3/ solenoid cartridge valve and the GADA line-mounting body. In this case, ports and 3 are used. Port is plugged.

4 6 Installation information ATTENTION! Only qualified personnel with mechanical skills may carry out any maintenance work. Generally, the only work that should ever be undertaken is to check, and possibly replace, the seals. When changing seals, oil or grease the new seals thoroughly before fitting them. These size 6, / solenoid operated directional cartridges can also be fitted in the AC or AD cavities, and in such cases port 3 then has the same function as port. When fitting the cartridges, use the specified tightening torque for the mounting screws. No adjustments are necessary, since the cartridges are set in the factory. 7 Hand lever fitted on solenoid (optional) As an option, the WC... series of / solenoid operated directional seat valves are available with an additional hand lever. Two models can be supplied; the HHB hand lever with detent feature, and the HHNB hand lever without detent feature. Hand levers can only be fitted to valves that have a manual override Ø ) ) Operated position /5 -P--EN-/5.6
