Burkert Type 0331 (SKU 363247) is a direct-acting, media-separated pivoted armature solenoid valve designed for controlling, shutting off, and dosing neutral and aggressive media. The solenoid actuator and the medium chamber are separated from each other by a separating membrane 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 lyes.

This specific 363247 variant features a Polypropylene (PP) body, EPDM seals, a 3.0 mm orifice, and a Bürkert flange 32 x 46 version A2 connection. It operates on 24 V DC and supports a pressure range from -1.00 bar up to 6.00 bar, making it suitable for vacuum applications.

Key Features

• Direct-acting, media-separated valve
• Maintenance-free pivoted armature technology
• Service-friendly manual override
• Epoxy coil thermal insulation class H
• Degree of protection IP65 with correctly connected cable plug
