BURKERT 387300 (Type 0331) is a direct-acting, media-separated pivoted armature solenoid valve. It features a 2/2-way normally closed (Circuit Function A) configuration with a brass body, NBR seal, and a Bürkert-specific flange connection. The solenoid coil is moulded with a chemically resistant epoxy, and the coil system is separated from the medium by a diaphragm, making it highly reliable for various industrial applications. This specific model operates at 24V DC and handles pressures from 0 to 16 bar.
