Burkert Type 0330 (Article 461284) is a direct-acting, media-separated pivoted armature solenoid valve. It features maintenance-free pivoted armature technology and a vibration-proof, block screwed coil system. 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 0330 is equipped with a service-friendly, robust manual override for start-up and testing.

Dimensions

Metal Body (Standard Variant)

Note

• Dimensions in mm
• For metal bodies, the minimum thread length at the middle connection is 7.5 mm.
• Screw-in depth of G 1/4 connection threads: When using pipe fittings, select variants with G 1/8, as the screw-in depth with G 1/4 is not sufficient.
