BURKERT 23640 Type 0330 is a direct-acting, media-separated pivoted armature solenoid valve. Configured as a 3/2-way normally closed valve, it features a 2.0 mm orifice, G 1/4 internal thread, and operates on 24 V DC. The solenoid coils are moulded with a chemically resistant epoxy. Since the coil system is separated from the medium by a diaphragm, the valve is especially suitable for critical media. The 23640 model is equipped with a brass body and FKM (Fluor rubber) seals, making it highly durable for industrial applications.
