Product Description:
The Burkert 6281 series belongs to the S.EV lineup as a servo-assisted 2/2-way diaphragm solenoid valve. It is engineered to provide dependable shut-off, dosing, and filling capabilities for neutral gaseous and liquid media. Constructed with a stainless steel body combined with an EPDM (ethylene-propylene-diene rubber) seal, the valve ensures outstanding corrosion resistance while maintaining flexibility at low temperatures, making it ideal for demanding industrial environments.
This valve requires a minimum differential pressure to operate efficiently. Its vibration-resistant coil system, which is centrally screwed and features a damped design, contributes to quiet closing actions and extends the service life. The standard version comes with a brass housing that complies with all European drinking water standards (KTW/W270), and for specific markets, a dezincification-resistant brass option is available. Additionally, a stainless steel variant is offered to meet various application requirements.
To optimize power efficiency during operation, the Burkert 6281 series can be fitted with coils incorporating "Kick and Drop" (KD) electronic assemblies, utilizing double coil technology. For straightforward maintenance and commissioning, a manual override option is also provided. When paired with a suitable cable plug conforming to DIN EN 175301-803 Form A, these valves achieve an IP65 protection rating. Moreover, models with a stainless steel housing meet the NEMA 4X standard.
Installation is flexible, allowing the valve to be positioned in any orientation, though mounting it with the actuator upright is preferred to ensure optimal performance.
Features:
Stainless Steel Body Construction
The body is made from stainless steel, ensuring excellent resistance to corrosion when exposed to aggressive media and demanding environmental conditions.
EPDM Seal
Equipped with an EPDM (Ethylene-Propylene-Diene Rubber) seal, this product offers outstanding resistance to water, dilute acids, alkalis, and various other media. It is suitable for media temperatures ranging from -30°C up to +90°C, and can handle up to +100°C when paired with an epoxy coil.
Servo-Assisted Diaphragm Design
The servo-assisted diaphragm design guarantees dependable operation for shut-off, dosing, and filling processes involving neutral and mildly aggressive media.
Normally Closed Configuration
This device features a normally closed (NC) circuit function, providing fail-safe operation that fulfills critical process control requirements.
Wide Port and Orifice Range
Available port sizes range from G1/4 to G2, with orifice diameters between 10 mm and 40 mm, enabling compatibility with a wide variety of flow demands.
Wide Pressure Range
The product can operate efficiently within a pressure range of 0.2 bar to 16 bar, accommodating diverse industrial needs.
Standard 8W Coils
Featuring standard 8W coils, it supports a 100% continuous duty cycle to ensure reliable and long-lasting operation.
Multiple Voltage Options
It is available in several voltage variants including DC24V, AC24V, and AC220V, each with a tolerance of ±10%, making it suitable for global applications.
IP65 / NEMA 4X Protection
The unit is dust-tight and protected against water jets when used with an appropriate cable plug, meeting IP65 and NEMA 4X standards.
Vibration-Proof Coil System
A centrally screwed coil system ensures secure and reliable operation even under demanding industrial vibration conditions.
Damped Design for Quiet Closing
The damped design minimizes noise during closing, making it well-suited for use in noise-sensitive environments.
Energy-Saving Option
Incorporating Kick-and-Drop (KD) double coil technology, this option reduces power consumption throughout operation.
Manual Override Option
A service-friendly manual override is available, facilitating easy maintenance and commissioning procedures.
Drinking Water Approvals
The standard brass housing complies with all European drinking water regulations, making it safe for potable water applications.
Explosion-Proof Variants
For use in hazardous areas, ATEX certified explosion-proof versions are available.
Flexible Installation
The device can be installed in any orientation; however, installation with the actuator in an upright position is preferred for optimal performance.
