New product

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...

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...

Solenoid coil with an MA certificate

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...

Ex-proof valves

The proven directly operated flow controller from Wandfluh, in the nominal size of M33, is now also available in an explosion protection execution. The valve is available as a 2-way function with the designation QNBPM33. The solenoid coil is explosion protection certified for underground and opencast mining and can be used worldwide. The corresponding approvals exist for ATEX, IECEx, EAC, INMETRO,...
