BURKERT 20015378 (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.

Key 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

Approvals and Conformities

Depending on the specific variant, Type 6014 valves can be supplied with various approvals including ATEX/IECEx (Zone 1/21, Zone 2/22), UL Listed/Recognized for USA and Canada, CSA, FM, CRN, FDA, USP, DNV GL classification, and DIN EN 45545 for fire protection on railway vehicles.

Explosion Protection

The maximum medium temperature must never exceed the permitted temperature class (T4: +135 °C, T5: +100 °C, T6: +85 °C) minus 5 K for explosion-proof variants.
