The 6240 valve is a servo-assisted piston valve. The stopper and plunger guiding tube are welded together to enhance pressure resistance and leak-tightness. Various seal material combinations are available depending on the application. The housing design and surface quality enable maximum flow rates. The coils are moulded with chemically resistant epoxy. An optional sliding ring bearings increases the life cycle with dry gases. To reduce power consumption in operation, coils with "Kick and Drop" (KD) electronics assembly (double coil technology) are available.

Servo-assisted and compact piston valve with diameter of up to DN 13
Vibration-resistant , screwed coil system
Energy-saving double coil technology with kick and drop variant
Safe opening with hard-coupled piston system
Explosion proof versions
