5404 Servo-Assisted 2/2-Way Piston Valve
Brand: Burkert Fluid Control Systems
The 5404 valve is a servo-assisted piston valve available in both NC and NO versions.
A minimum differential pressure is required for the valve switching function. The standard brass housing satisfies all European drinking water requirements.
The solenoid coils are moulded with high-quality polyamide.
For reduced energy requirement, all coils can be delivered with electronic power reduction.
In combination with a plug in accordance with DIN EN 17301-803 Form A, the valves satisfy protection class P65.
Features
- Servo-assisted piston valve with diameter of up to DN 25
- Vibration-proof, screwed coil system
- Moulded housing with high surface quality
- Explosion proof versions
- Suitable for gas and steam applications
