BURKERT 20139454 (Type 0330) is a direct-acting, media-separated pivoted armature valve. As a 3/2-way variant, it can be used as a distributor or mixing valve. 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 20139454 is equipped with a manual override for start-up and testing.

Features

• Direct-acting, media-separated valve up to nominal diameter DN 5
• Maintenance-free pivoted armature technology
• Vibration-proof, block screwed coil system
• Service-friendly, robust manual override
