Features:
Servo-Assisted Operation
This system employs line pressure to actuate the diaphragm, enabling dependable control over large flow rates up to DN 50. It achieves this functionality using a compact solenoid, ensuring efficient and effective operation.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) variant features a high-power pulse that provides positive valve opening, followed by a low-power holding current. This design significantly reduces energy consumption while maintaining a cool operating temperature.
Robust and Quiet Design
Vibration-Resistant Coil
The coil system is centrally screwed in place, guaranteeing a secure electrical connection. This construction also offers high resistance against vibration and shock, enhancing reliability under demanding conditions.
Damped Closing
An optimized pilot circuit combined with a damping mechanism ensures the valve closes smoothly and quietly. This feature helps minimize water hammer effects and reduces operational noise, contributing to a more durable and comfortable environment.
Versatile Materials and Certifications
The valve bodies are available in multiple materials such as Brass and Stainless Steel. The standard brass option meets European drinking water standards, ensuring safety and compliance.
For hazardous environments, explosion-proof variants come with ATEX and IECEx certifications, making them suitable for use in potentially explosive atmospheres.
Easy Maintenance and Commissioning
An optional manual override feature facilitates straightforward testing, maintenance, and emergency operation during power failures, enhancing operational flexibility.
Long Service Life
A broad selection of diaphragm materials, including NBR, EPDM, and FKM, ensures compatibility with various media. This variety allows for sustained sealing performance and extended service life.

Support and Services:
Burkert solenoid valves are precision-engineered components designed for reliable fluid control in a wide range of industrial applications. To ensure optimal performance and longevity of your Burkert solenoid valve, it is important to follow proper installation, operation, and maintenance procedures.
Installation: Before installation, verify that the valve specifications match the system requirements, including voltage, pressure, and media compatibility. Ensure the valve is installed in the correct flow direction as indicated on the valve body. Use appropriate sealing materials and avoid over-tightening to prevent damage.
Operation: Burkert solenoid valves operate by using an electromagnetic coil to open or close the valve. Ensure that the power supply matches the valve’s voltage and frequency specifications. Avoid continuous energizing beyond the recommended duty cycle to prevent coil overheating. For valves used in critical applications, periodic functional checks are recommended.
Maintenance: Regular maintenance is essential to maintain valve performance. Inspect the valve for signs of wear, corrosion, or contamination. Clean or replace filters and strainers upstream of the valve to prevent debris from entering. If the valve exhibits irregular operation, check the coil resistance and replace the coil if necessary. Always depressurize the system before performing any maintenance.
Spare Parts and Repairs: Use only genuine Burkert replacement parts to ensure compatibility and reliability. For repairs beyond routine maintenance, consult Burkert’s technical documentation or authorized service centers. Unauthorized modifications or repairs may void the warranty and affect valve performance.
Technical Support: For detailed product information, troubleshooting assistance, or application advice, refer to the Burkert technical manuals and datasheets available on the official website. Burkert’s technical support team is equipped to provide expert guidance to help resolve any issues and optimize valve performance.
