Product Description:
The Type 6281 is a servo-assisted 2/2-way diaphragm solenoid valve produced by the German manufacturer Bürkert. This particular model is Normally Closed (NC) and features a brass body. It is part of the S.EV series, which is designed for general fluid control applications.
The operation of the valve involves opening and closing the diaphragm, which is actuated by the pressure differential of the medium passing through. The standard brass body meets European certifications for drinking water, including KTW and W270. For certain international water treatment applications, a dezincification-resistant brass version is also available.
The nominal diameter of the valve varies from DN10 to DN50, and it is offered with two types of internal threads: G thread and NPT thread. This solenoid valve is suitable for use with neutral media such as water, compressed air, and weak acidic or alkaline liquids.
Overall, the Type 6281 is a versatile solenoid valve ideal for industrial processes involving fluid on-off control, flow shut-off, and precise medium dosing.
Features:
The servo-assisted diaphragm design allows the maximum Kv flow coefficient to reach up to 3.8 m³/h. This advanced mechanism ensures efficient fluid control and optimal performance.
Featuring a damped silent switching design, the system effectively eliminates the impact of water hammer. This innovation ensures smooth operation and reduces noise during valve actuation.
The device operates with a minimum differential pressure of 0.2 bar and supports a wide working pressure range from 0.2 to 16 bar, making it suitable for various applications.
Constructed with a standard forged brass body, the product integrates high-precision molding to guarantee durability and quality. It has successfully passed the European drinking water certifications KTW and W270, ensuring that no harmful substances leach into the water.
For long-term anti-corrosion performance in water pipelines, an optional dezincification-resistant brass version is available, providing enhanced protection against material degradation.
