Burkert Type 6014 (SKU 20142531) is a direct-acting, compact 3/2-way plunger valve with a diameter of up to DN 2.5. 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.

The valve features a vibration-proof, bolted coil system and offers options such as a banjo threaded connection for direct mounting on pneumatic valves, explosion-proof variants, and energy-saving variants with Kick and Drop coils for the reduction of electrical power consumption during operation.

Product Installation

Control for impulse variant with polarity reversal control

• Please use only the cable plug without electrical wiring for the impulse variant.
• Pulse duration at least 50 ms.

Polarity (marked on the coil with a label):

• - switch ON + : valve open ((+) on terminal 2 and (-) on terminal 1)
• + switch OFF - : valve closed ((+) on terminal 1 and (-) on terminal 2)
