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…

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…

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…

For use in explosion hazard areas, Wandfluh has also certified the proven MKY coil for the mining sector in China. This coil is available in the 24VDC variant with a power of 15 watts. In addition, the option is also available with integrated amplifier electronics. By this, proportional valves can be controlled directly with an analogue voltage or current signal.

The electronics with a…
