BURKERT 20036646 (Type 6013) is a direct-acting and compact 2/2-way plunger solenoid valve. The specific 20036646 model features a stainless steel body, EPDM seal, 2.0 mm orifice, flange connection, and operates on 24V DC with a pressure range of 0 to 16 bar. It is configured for Circuit Function B (normally open). Across the Type 6013 family, the stopper and the core guide tube are welded together to increase pressure resistance and leak-tightness. A variety of seal material combinations are available to suit different applications. A Bürkert-specific flange variant (SFB) enables the space-saving arrangement of valves on a multiple manifold. Kick and drop coils are available to reduce electrical power consumption during operation.
