BURKERT Type 0330 (SKU 452785) is a direct-acting, media-separated pivoted armature solenoid valve. It is available as a 2/2 and 3/2-way variant, with SKU 452785 specifically configured as a 3/2-way normally closed valve (Circuit Function C). 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 such as aggressive acids and alkalis.

The Type 0330 is equipped with a service-friendly, robust manual override for start-up and testing. It features maintenance-free pivoted armature technology and a vibration-proof, block screwed coil system.
