Product Description:
The Bürkert Type 6281
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.
