Burkert Type 6281 Servo-Assisted 2/2-Way Diaphragm Solenoid Valve (ID: 00221898)

The Bürkert 00221898 is an indirect-acting (servo-assisted) 2/2-way normally closed (NC) diaphragm solenoid valve from the Type 6281 EV series. Engineered for handling larger flow rates of clean, neutral fluids like water and alcohols, this model features a durable brass body satisfying European drinking water requirements, a 13 mm orifice size, and high-grade EPDM seals.Because it is a servo-assisted valve, it utilizes the pressure differential of the medium to help move the internal membrane, requiring a minimum differential pressure of 0.2 bar to function properly (with an upper operating threshold of up to 16 bar). It features a specialized damped design to prevent water hammer and ensure quiet closing. This specific part number comes equipped with a energy-efficient 24V DC coil and standard $G\ 1/2"$ female threaded port connections.
