The new Festo solenoid valve VZWD can switch at any pressure from 0 to 90 bar without differential pressure—even in closed media circuits. This new valve is ideal for high-pressure and dosing applications. It can be operated with water, air and neutral media. VZWD are 2/2-way valves, normally closed, and are poppet valves with return springs. The series includes brass and stainless steel valves with an FKM seat-seal material. The valves come with either NPT or G threads and should be mounted with the coil on top. Sizes range from 1/8- to 1/4-inch, and nominal diameters from 1 to 6 mm are available. Operating pressure ranges from 0 to 10 bar, depending on coils used and nominal diameter. The process valve’s nominal pressure is PN 40.
