Pressure reducing valve manually adjustable

The cartridge valve in the nominal size of U10 controls the manually adjusted output pressure independently of the input pressure and the volume flow. Through the 3-way function, overpressures at the output of the valve can be actively relieved against the tank. This guarantees, at all times, a stable pressure on the consumer in the system. The optimised valve design results in very good...

Proportional throttle valve normally open

The tried and tested direct operated throttle valve in the nominal size M33 is now also available in a normally open execution. The valve is used in applications where maximum flow is required when the solenoid is in a deenergised state.

Via the solenoid current, the proportional valve can continuously adjust volume flows up to max. 55 l/min and be used in the pressure range up to 350 bar. The...

Neues Produkt

Das bewährte direktgesteuerte Drosselventil der Nenngrösse M33 ist nun auch in einer stromlos offenen Ausführung erhältlich. Das Ventil wird in Anwendungen eingesetzt, wo der maximale Durchfluss im stromlosen Zustand des Magneten gefordert ist.

Über den Magnetstrom kann das Proportionalventil Volumenströme bis max. 55 l/min stufenlos verstellen und im Druckbereich bis 350 bar eingesetzt werden....

Integrated bipolar protection diode

Wandfluh has extended the solenoid coil WDE45 / 23x50 with a 28VDC voltage. The coil can be sensibly used where the supply voltage nominally rather is at 28VDC. If a 24V coil is used for this voltage, this leads to a reduction in the operating condition with respect to the maximum ambient temperature and the maximum duty factor. With the 28V coil, this situation can be avoided, and the...
