Catalog excerpts

DATA SHEET Servo-assisted 2/2-way piston valve • 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 Product variants described in the data sheet may differ from the product presentation and description. Type 2518 Cable plug, form A according to DIN EN 175301-803 Type 2509 Cable plug, form A according to DIN EN 175301-803 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 electronics assembly (double coil technology) are available. Standard | EU | en | 2024-05-15 | 32 © Christian Bürkert GmbH & Co.
