6240 Servo-Assisted 2/2-Way Piston Solenoid Valve
Brand: Burkert Fluid Control Systems
The 6240 valve is a servo-assisted plunger valve. The stopper and plunger guiding tube are welded together to enhance pressure resistance and leak-tightness. Various seal material combinations are available depending on the application.
The housing design and surface quality enable maximum flow rates. The coils are moulded with chemically resistant epoxy. An optional sliding ring bearings increases the life cycle with dry gases.
Kick and Drop electronics are available for over-excitation (plug 2511) and reduced electrical power consumption in operation.
In combination with a plug in accordance with DIN EN 17301-803 Form A, the valves satisfy protection class IP65. Stainless steel valves satisfy NEMA 4X.
Features- Servo-assisted and compact piston valve with diameter of up to DN12
- Vibration-resistant, screwed coil system
- Increased leak-tightness with welded plunger guiding tube
