Burkert Type 6014 is a direct-acting plunger valve. The stopper and core guide tube are welded together to enhance pressure resistance and leak-tightness. Various seal material combinations are available depending on the application. A Bürkert-specific flange variant (SFB) enables space-saving arrangement of valves on a manifold. Kick and Drop coils are available for the reduction of electrical power consumption during operation.

Features

• Direct-acting, compact valve with diameter of up to DN 2.5
• Vibration-proof, bolted coil system
• Banjo threaded connection for direct mounting on pneumatic valves
• Explosion proof variants
• Energy-saving variants with Kick and Drop available
