burkert FLUID CONTROL SYSTEMS Servo-assisted 2/2 way diaphragm valve • Servo-assisted diaphragm with diameter of up to DN50 • Vibration-proof, central screwed coil system • Damped design for quiet closing • Service-friendly manual override • Explosion-proof versions Type 6281 can be combined with... DTS 1000152082 EN Version: K Status: RL (released | freigegeben | valide) printed: 10.09.2018 The 6281 valve is a servo-assisted solenoid valve of the S.EV series. A minimum differential pressure is always required for the function of the valve. Various diaphragm material combinations and methods of operation are available depending on the application. The standard brass housing satisfies all European drinking water requirements. Dezincification-resistant brass is available for other markets. The housing offering is rounded out by a stainless steel version. For reduced energy requirement, all coils can be delivered with electronic power reduction. The valve can be equipped with manual override for easy maintenance and commissioning. In combination with a plug in accordance with DIN EN 175301 - 803 Form A, the valves satisfy protection class IP65 - in combination with a stainless steel housing NEMA 4X.
