Product Description:
The Bürkert 6281 series represents a servo-assisted 2/2-way diaphragm solenoid valve, specifically engineered for dependable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid substances, including compressed air and water. For optimal valve functionality, a minimum differential pressure is necessary.
This valve features a vibration-resistant coil system that is centrally screwed in place, combined with a damped design to guarantee quiet closing operations and an extended service life. To enhance energy efficiency during operation, variants equipped with the "Kick and Drop" (KD) electronics assembly, utilizing double coil technology, are available to significantly reduce power consumption.
The valve’s standard housing is made of brass, complying with all European standards for drinking water safety. Additionally, it can be fitted with a service-friendly manual override, facilitating straightforward maintenance and commissioning processes. When paired with an appropriate cable plug, such as the Type 2518, the valves achieve an IP65 protection rating.
Installation is flexible as the valve can be positioned in any orientation; however, it is recommended to install it with the actuator facing upright for best performance.
Features:
Servo-Assisted Diaphragm Design
The valve features a servo-assisted diaphragm design that ensures dependable performance in applications such as shut-off, dosing, and filling. This design enhances operational reliability across various processes.
Reliable and Safe Operation
Configured as Normally Closed (Circuit Function A - NC), the valve provides fail-safe operation suitable for critical process control requirements. Additionally, a service-friendly manual override allows easy maintenance and commissioning when necessary.
Robust Construction and Seal Materials
Constructed with a durable brass body, the valve exhibits excellent resistance to corrosion, contributing to a prolonged service life. The use of NBR seal material ensures reliable performance across a wide variety of neutral media, operating effectively within a temperature range of -10°C to +80°C.
Versatile Flow and Pressure Capabilities
The valve accommodates diverse flow requirements with a wide selection of port sizes ranging from G1/4 to G2, and orifice sizes between 10 mm and 40 mm. It also supports a broad pressure range from 0.2 bar up to 16 bar, making it suitable for numerous industrial applications.
Electrical and Environmental Features
Equipped with standard 8W coils, the valve is capable of continuous operation at 100% duty cycle, ensuring reliable long-term use. Multiple voltage options are available, including DC 24V, AC 24V, and AC 220V, each with a tolerance of ±10% for global compatibility. The valve is rated IP65, guaranteeing dust-tight protection and resistance to water jets when used with an appropriate cable plug. Furthermore, a centrally screwed coil system enhances vibration resistance, ensuring secure operation even in demanding industrial environments.
Additional Functional Advantages
Designed with a damped mechanism, the valve closes quietly, making it ideal for noise-sensitive environments. An energy-saving Kick-and-Drop (KD) double coil technology minimizes power consumption during operation. The standard brass housing meets all European standards for drinking water approval, adding to its versatility. For hazardous locations, explosion-proof variants that comply with ATEX certification are also available.
Flexible Installation Options
Installation of the valve is highly flexible, allowing positioning in any orientation, although the preferred setup is with the actuator in an upright position to ensure optimal performance.
