Product Description:
The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve, engineered for dependable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media, including compressed air and water. It is important to note that a minimum differential pressure is necessary for the valve to operate correctly.
Designed with a vibration-proof, centrally screwed coil system, the valve ensures stable performance. Its damped construction contributes to a quiet closing operation, enhancing overall system noise reduction. The solenoid coils are encapsulated in chemically resistant epoxy, providing durability and protection against harsh environments.
To optimize energy efficiency, there are coil options available with electronic power reduction, which help lower power consumption during operation. The valve's standard brass housing complies with all European drinking water standards (KTW/W270), and for markets requiring enhanced corrosion resistance, a dezincification-resistant brass variant is offered.
Maintenance and commissioning are simplified through an optional manual override feature, designed for user-friendly serviceability. When paired with an appropriate cable plug conforming to DIN EN 175301-803 Form A, the valve achieves an IP65 protection rating. Installation flexibility is a key attribute of this valve, as it can be mounted in any orientation, though positioning the actuator upright is recommended for optimal performance.
Features:
Servo-Assisted Diaphragm Design
The valve is equipped with a servo-assisted diaphragm design that ensures reliable performance during shut-off, dosing, and filling processes when handling neutral media. This design enhances operational precision and dependability across various applications.
Normally Open Configuration
Featuring a circuit function B (normally open), the valve provides fail-open operation. This means the valve remains open when there is no power supply, making it suitable for applications that require uninterrupted flow in de-energized states.
Durable Brass Body
Constructed from high-quality brass, the valve body offers excellent resistance to corrosion and ensures a long service life. This robust material guarantees durability even under challenging environmental conditions.
Reliable NBR Seal Material
The seals are made from NBR (Nitrile Butadiene Rubber), providing dependable performance within a temperature range of -10°C to +80°C. This material choice delivers consistent sealing under varying thermal conditions.
Wide Port and Orifice Options
Designed to meet diverse flow requirements, the valve comes in port sizes ranging from G1/4 up to G2, with orifice diameters between 10 mm and 50 mm. This variety accommodates a broad spectrum of industrial needs.
Operating Pressure Range
The valve functions efficiently across a wide pressure range, from as low as 0.2 bar up to 16 bar, ensuring adaptability across different system pressures.
Standard 8W Coils
Equipped with standard 8-watt coils, the valve supports a 100% continuous duty cycle. This feature guarantees reliable and consistent operation over extended periods.
Multiple Voltage Options
To accommodate global applications, the valve is available in various voltage configurations including DC 24V, AC 24V, and AC 220V, all with a tolerance of ±10%. This ensures compatibility with different power systems worldwide.
IP65 Protection Rating
The valve is rated IP65, making it dust-tight and protected against water jets when paired with an appropriate cable plug. This protection level enhances reliability in harsh environments.
Vibration-Proof Coil System
Featuring a centrally screwed coil system, the valve remains secure and operational even in demanding industrial environments experiencing significant vibrations.
Damped Design for Quiet Operation
The valve incorporates a damped design to ensure quiet closing, reducing noise levels and making it suitable for use in noise-sensitive settings.
Energy-Saving Technology
Utilizing Kick-and-Drop (KD) double coil technology, the valve minimizes power consumption during operation, contributing to energy efficiency.
Manual Override Function
A manual override option is available to facilitate easy maintenance and commissioning, making the valve service-friendly.
Drinking Water Compliance
The standard brass housing complies with all European drinking water standards, ensuring safe operation in potable water applications.
Explosion-Proof Variants
For hazardous area applications, ATEX-certified explosion-proof versions of the valve are available, enhancing safety in explosive environments.
Flexible Installation Options
The valve can be installed in any orientation; however, it is recommended to position the actuator upright for optimal performance.
