The 2261 valve is a servo-assisted solenoid valve . 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 body material is can also rounded out by a stainless steel version(1761). 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. the valves satisfy protection class IP65
·Servo-assisted diaphragm valve with an orifice up to DN50
·Explosion-proof versions
·Service-friendly manual override
·Timing switch can be equipped
