Wandfluh spool valve for explosion protection

With the new Wandfluh spool valve, directional functions in the nominal size of 4 can now be realised for zone 0. The valve is available as 4/3 and 4/2-way function and as a detented version. With a leakage of less than 20 ml/min at 120 bar, the valve is ideally suited for applications where small leakages play an important role. The valve with the designation WDZFA04 is also ideally suited for pilot control functions of any kind. It can be operated up to a maximum of 350 bar and switch volume flows of up to 10 l/min. For the actuation of the valve, the tried and tested Wandfluh solenoid coil Ex-certified according to ATEX / IEC from equipment group I + II is used.
