Product Description:
The Bürkert Type 6281 is a high-performance, servo-assisted solenoid diaphragm valve with sizes up to DN 50. It operates on a servo-assisted principle, requiring a minimum differential pressure to function and enabling the control of large flows with a compact and energy-efficient coil system.
The valve body is available in different materials to meet various demands. It comes in standard brass that complies with European drinking water regulations, dezincification-resistant brass, and stainless steel, meeting global market standards and accommodating different types of media.
Equipped with integrated energy-saving "Kick and Drop" electronics featuring double coil technology, the Type 6281 ensures reliable opening while significantly reducing operating power consumption. Its design includes features such as vibration resistance, damped quiet closing, and an optional manual override, making it the ideal solution for industrial automation applications that prioritize efficiency, reliability, and long service life.
Features:
Servo-Assisted Operation
Utilizes line pressure for diaphragm actuation, allowing reliable control of large flow rates (up to DN 50) with a compact solenoid.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) variant uses a high-power pulse for positive opening and a low-power hold for reduced energy consumption and cool operation.
Robust & Quiet Design
- Vibration-Resistant Coil: Centrally screwed coil system ensures secure electrical connection and high resistance to vibration and shock.
- Damped Closing: Optimized pilot circuit and damping mechanism ensure soft, quiet closing, minimizing water hammer and operational noise.
Versatile Materials & Certifications
- Multiple body materials: Brass, Stainless Steel. Standard brass complies with European drinking water requirements.
- Explosion-proof variants: Available with ATEX / IECEx certifications for use in hazardous areas.
Easy Maintenance & Commissioning
Optional manual override allows for easy testing, maintenance, or emergency operation during power loss.
Long Service Life
A wide range of diaphragm materials (e.g., NBR, EPDM, FKM) ensures media compatibility and long-term sealing integrity.
