Solenoid spool valve in stainless steel execution

Wandfluh has extended the proven flange spool valves for the modular valve construction with an execution for use in very corrosive environments. 
The valve is made from stainless materials and high-quality surface protection. It can switch volumes up to 50 l/min at up to 350 bar. Executions with 2- and 3-way functions are available. An optional detent enables valve actuation with a short electrical impulse, thus reducing energy consumption.

The valve body and the cover are made from stainless steel (AISI 316L). The solenoid coil and the armature tube are very well protected against corrosion by their zinc-nickel coating (1,000 h in salt spray test). The direct operated valve of nominal size NG6 is available as a 4/2-way and 4/3 function with the designation WDYFA06...K9. The valve controls the direction of flow and thus the direction of movement or rotation of hydraulic actuators. It is mainly used in applications with continually changing weather conditions or in the vicinity of the sea.
