BURKERT 20034129 is a direct-acting, compact 3/2-way plunger solenoid valve belonging to the Type 6014 family. This specific model features a Banjo G 1/4 threaded connection for direct mounting on pneumatic valves, a 2.0 mm orifice, a PPS (Polyphenylene sulphide) body, and FKM seals. It operates as a normally closed (Circuit Function C) valve and is equipped with a 230V / 50Hz AC coil and a manual override for easy commissioning and maintenance.

The stopper and core guide tube are welded together to enhance pressure resistance and leak-tightness. The coil is encapsulated with polyamide and offers a vibration-proof, bolted coil system.
