Product Description:
The Burkert 6281 series represents a servo-assisted 2/2-way diaphragm solenoid valve belonging to the S.EV series. It is specifically engineered to provide reliable shut-off, dosing, and filling functions for neutral gaseous and liquid media. Constructed with a stainless steel body combined with an EPDM (ethylene-propylene-diene rubber) seal, this valve delivers exceptional corrosion resistance and maintains flexibility at low temperatures, making it suitable for demanding industrial environments.
Operation of the valve requires a minimum differential pressure to ensure proper functionality. Its vibration-resistant design features a centrally screwed coil system along with a damped mechanism, which together guarantee quiet closing and an extended service life. The standard model includes a brass housing that complies with all European drinking water standards (KTW/W270). For other markets, there is an option for dezincification-resistant brass, and additionally, a stainless steel version is also available to meet specific application needs.
To enhance energy efficiency during operation, the valve can be equipped with coils utilizing the "Kick and Drop" (KD) electronics assembly, also known as double coil technology, which reduces power consumption. Maintenance and commissioning are facilitated by an optional manual override feature. With the correct cable plug connection following DIN EN 175301-803 Form A standards, the valve achieves an IP65 protection rating. When combined with the stainless steel housing, it also meets NEMA 4X requirements.
The valve’s design allows it to be installed in any orientation, although positioning the actuator upright is recommended for optimal performance.
Features:
Stainless Steel Body Construction
The body is constructed from stainless steel, providing exceptional resistance to corrosion. This makes it suitable for use with aggressive media and in demanding environments where durability is essential.
EPDM (Ethylene-Propylene-Diene Rubber) Seal
The EPDM seal offers outstanding resistance to water, dilute acids, alkalis, and various other media. It can withstand a wide range of temperatures from -30°C up to +90°C, and even up to +100°C when combined with an epoxy coil.
Servo-Assisted Diaphragm Design
This design ensures reliable operation for shut-off, dosing, and filling tasks involving neutral or mildly aggressive media, enhancing performance and longevity.
Normally Closed Configuration
The circuit function A (normally closed) provides fail-safe operation, which is vital for precise process control applications.
Wide Port and Orifice Range
Available port sizes range from G1/4 to G2, with orifice diameters between 10 mm and 40 mm, allowing for adaptation to a variety of flow requirements.
Wide Pressure Range
The system operates effectively within a pressure range of 0.2 bar up to 16 bar, accommodating diverse operational conditions.
Standard 8W Coils
Equipped with 8W coils that support a 100% continuous duty cycle, these coils ensure reliable performance over long-term use.
Multiple Voltage Options
To support global compatibility, the product is available in DC24V, AC24V, and AC220V variants, each with a ±10% voltage tolerance.
IP65 / NEMA 4X Protection
The unit is dust-tight and protected against water jets when paired with an appropriate cable plug, meeting IP65 and NEMA 4X standards.
Vibration-Proof Coil System
The coil mounting system is centrally screwed, providing secure and stable operation even in harsh industrial environments subject to vibrations.
Damped Design for Quiet Closing
The damped mechanism ensures low noise during closing, making it ideal for use in noise-sensitive settings.
Energy-Saving Option
Featuring Kick-and-Drop (KD) double coil technology, the device significantly reduces power consumption during operation.
Manual Override Option
A service-friendly manual override is available, facilitating easy maintenance and commissioning processes.
Drinking Water Approvals
The standard brass housing complies with all European drinking water standards, ensuring safety and suitability for potable water applications.
Explosion-Proof Variants
For hazardous area installations, ATEX certified explosion-proof versions are available.
Flexible Installation
The product can be installed in any orientation, although it is recommended to position the actuator in an upright position for optimal performance.
