Product Description:
The Type 6281 is a servo-assisted 2/2-way diaphragm solenoid valve, produced by the renowned German manufacturer Bürkert. This valve is part of the S.EV general fluid control series and features a Normally Closed (NC) configuration with a durable brass body.
The operation of the valve is based on a diaphragm that opens and closes, driven by the differential pressure of the medium flowing through it. Its brass body meets the stringent European drinking water standards, including certifications KTW and W270, ensuring safety and reliability. For applications in overseas water treatment projects, an optional dezincification-resistant brass variant is available.
The valve covers a range of nominal diameters from DN10 up to DN50, and it comes with two types of internal threads to suit various installation needs: G thread and NPT thread. It is designed to be compatible with neutral media such as water, compressed air, as well as weak acidic and alkaline liquids.
Due to its versatile nature, the Type 6281 serves as a universal solenoid valve widely used in industrial fluid systems. It is ideal for on-off fluid control, flow shut-off, and precise medium dosing, providing reliable performance in various applications.
Features:
The servo-assisted diaphragm design allows the valve to achieve a maximum Kv flow coefficient of up to 3.8 cubic meters per hour. This advanced mechanism ensures efficient fluid control in various applications.
Featuring a damped silent switching design, the system effectively eliminates the impact of water hammer, resulting in smooth and quiet operation. This enhances the longevity of the equipment and provides a more reliable performance.
The valve operates with a minimum differential pressure of just 0.2 bar, and it supports a working pressure range from 0.2 to 16 bar. This wide range makes it suitable for diverse pressure conditions in different systems.
Constructed with a standard forged brass body, the valve incorporates integrated high-precision molding to guarantee durability and precision. It has successfully passed the European drinking water certifications KTW and W270, ensuring no harmful substances are released into the water supply.
For applications requiring long-term resistance to corrosion in water pipelines, an optional dezincification-resistant brass variant is available. This option significantly enhances the valve's durability and reliability in demanding environments.
