The proven spool valves for use in Zone 0 are now available with an extended flow range. This in the nominal sizes NG4 and NG6. The two valves are available in 4/3- and 4/2-way functions and as detented execution. The maximum volume flow increases to 20 l/min with this variant. The valve is also ideal for all types of pilot control functions. It can be operated up to a maximum of 350 bar. If a…

The pressure reducing valve controls output pressures from 0 to 200 bar proportionally to the adjusted solenoid current. The valve is used in applications where pressures must be precisely controlled independently of the input pressure and this in explosion-hazard areas of zone 1 and 2. Via the solenoid current, the proportional valve can continuously adjust pressures up to max. 200 bar and be…

Wandfluh has revised the existing 2-way cartridge valve programme and equipped it with massively higher pressure resistance. In addition, the flow geometry has been optimized and thus the flow rate considerably increased.

The valve programme comprises the 5 nominal sizes NG16, 25, 32, 40 and 50, which cover the volume flow range from 360 l/min (NG16) to 2,500 l/min (NG50) and switch up to 630…

Another tutorial for "PASO profile generator" is available. It shows the basic functions and settings for this profile generator.
