Wandfluh has extended the proven roller valve with an execution for use in very corrosive environments. The valve is made from stainless materials and coated with high-quality surface protection. The valve can switch a volume flow of 60 l/min at up to 350 bar. The robust actuation roller can also absorb higher transverse forces and is very well protected against contamination. The direct operated valve of nominal size NG6 is available as a 4/2-way execution with the designation WDTFA06…K9.
This valve is used in applications in which purely mechanical operation is required and environmental conditions require high demands on corrosion resistance.
