Proportional Screw In Cartridge Valve

The exchangeable coil significantly simplifies the logistics, because the solenoid coil can also be retrofitted. The various alternatives make the Proportional Screw in Cartridge Valve a very flexible system. Different plug-voltage alternatives are available ex stock and are complemented with respect to individual adaptations-with the customary Wandfluh flexibility.

In addition, the performance of the valves has been increased by the improved solenoid coil. Therefore also ambient temperatures of up to 70°C can be accepted without any performance loss. With the improvement of the corrosion protection of the solenoid coil, depending on the version, the valves achieve a salt-spray resistance of over 500h.

Specification:

Available are valves with the standard cavities M22 and M33 in accordance with ISO 7789. Pressure relief valves are available as direct operated and pilot-operated versions up to volume flows of over 230 l/min and pressures of up to 350 bar. Apart from the optimised proportional throttle for volume flows of up to 63 l/min, the All-In-One valve QSPPM33 (tight seating volume flow controller) with mechanically preset c is in the Wandfluh product range.

By the preset Imin the series spread of the valves is reduced to a minimum, in order to guarantee a simplification of the valve commissioning. Typical applications for the qualitatively high-grade proportional screw-in cartridge valves are: - Sensitive adjustment of pressure, resp., volume flow-Speed control of hydro-motors-Cylinder control-and positioning-Individual adjustment of clamping-and tensioning force.
