BURKERT 453692 (Type 0330) is a direct-acting, media-separated pivoted armature solenoid valve designed for controlling, shutting off, and dosing neutral and aggressive media. This specific model (SKU 453692) is configured as a 3/2-way valve with Circuit Function C (normally closed). It features a robust brass body, FKM (Fluor rubber) seals, and an NPT 1/4 internal thread connection. The valve operates on a 24V DC power supply and supports a pressure range of 0 to 12 bar, making it highly suitable for critical industrial applications where reliable media separation and fast actuation are required.

The solenoid coils are moulded with a chemically resistant epoxy, and the coil system is separated from the medium by a diaphragm system. This maintenance-free pivoted armature technology ensures a long service life and vibration-proof operation. The valve is equipped with a service-friendly, robust manual override for easy start-up and testing.

Pressure Limitation

• The standard pressure range for DN 2.0 is up to 16 bar, however, the maximum medium pressure is limited to 12 bar for seal materials FKM and FFKM, which applies to this specific model (453692).

Functional Safety

During a long period of downtime, at least 1–2 switching operations per restart are recommended to ensure functional safety and prevent the core from seizing.
