BURKERT 20108881 Type 0330 is a direct-acting, media-separated pivoted armature 3/2-way solenoid valve. This specific explosion-proof variant features a stainless steel body, G1/4 internal thread, 4.0 mm orifice, and EPDM seals. It operates on 24V and is designed for a pressure range of -1.00 to 3.00 bar. The coil system is separated from the medium by a diaphragm, making it highly suitable for critical and aggressive media.

System Description

The pivoted armature valves are direct-acting solenoid valves. The solenoid actuator and the medium chamber are separated from each other by a separating membrane system. The valves are fast-acting and have a long service life.

• Maintenance-free pivoted armature technology
• Vibration-proof, block screwed coil system
• Explosion-proof variant (Ex mb IIC T4 Gb, II 2 D Ex mb IIIC T130°C Db)

Circuit Function

Circuit function D (CF D): 3/2-way solenoid valve, direct-acting, normally open. Inlet port 1 (P/NO) connected with outlet port 2 (B/OUT), exhaust port 3 (R/NC) closed in rest position.
