Product Description:
The Bürkert Type 6281 is a high-performance, servo-assisted solenoid diaphragm valve with sizes up to DN 50. Operating on a servo-assisted principle, it requires a minimum differential pressure to function, enabling the control of large flows with a compact and energy-efficient coil system.
The valve body is available in standard brass (compliant with European drinking water regulations), dezincification-resistant brass, and stainless steel to meet the demands of various media and global market standards. Featuring integrated energy-saving "Kick and Drop" electronics with double coil technology, it ensures reliable opening while significantly reducing operating power consumption.
Combined with its vibration-resistant design, damped quiet closing, and optional manual override, the Type 6281 is the ideal solution for industrial automation applications demanding 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.
