Product Description:
The Burkert 6281 series belongs to the S.EV range and is a servo-assisted 2/2-way diaphragm solenoid valve. It is specifically engineered to provide dependable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media. Constructed with a stainless steel body coupled with an EPDM (ethylene-propylene-diene rubber) seal, this valve ensures excellent resistance to corrosion and maintains flexibility even at low temperatures, making it ideal for challenging industrial environments.
For proper operation, the valve requires a minimum differential pressure. The coil system is vibration-resistant and centrally screwed, combined with a damped design that guarantees quiet closing and extends the valve’s service life. The standard housing is made of brass and complies with all European drinking water standards (KTW/W270). Additionally, a dezincification-resistant brass variant is available for markets with specific requirements. A stainless steel version further complements the product lineup.
To enhance energy efficiency during operation, the valve is offered with coils equipped with "Kick and Drop" (KD) electronics assembly, featuring double coil technology to reduce power consumption. Maintenance and commissioning are simplified through the availability of a manual override option. When used with a matching cable plug according to DIN EN 175301-803 Form A, the valve meets the IP65 protection rating; if a stainless steel housing is chosen, it achieves a NEMA 4X rating.
Installation of the valve is flexible, as it can be mounted in any orientation. However, it is recommended that the actuator be positioned upright to ensure optimal performance.
Features:
Stainless Steel Body Construction ensures outstanding corrosion resistance, making it ideal for use with aggressive media and in demanding environmental conditions.
The EPDM (Ethylene-Propylene-Diene Rubber) Seal delivers superior resistance to water, dilute acids, alkalis, and various other media. It supports media temperature ranges from -30°C up to +90°C, with the possibility of reaching +100°C when used with an epoxy coil.
Featuring a Servo-Assisted Diaphragm Design , this product guarantees dependable operation for shut-off, dosing, and filling tasks, particularly with neutral and mildly aggressive media.
The Normally Closed Configuration (Circuit Function A, NC) provides fail-safe operation, meeting critical process control requirements.
With a Wide Port and Orifice Range , port sizes vary from G1/4 to G2, while orifice sizes range between 10 mm and 40 mm, allowing flexible adaptation to different flow demands.
The device supports a Wide Pressure Range from 0.2 bar up to 16 bar, accommodating various pressure requirements.
Equipped with Standard 8W Coils , it offers a 100% continuous duty cycle, ensuring reliable and long-term operation under continuous use.
Multiple voltage options are available, including DC24V, AC24V, and AC220V , each with a tolerance of ±10%, making it compatible with global power systems.
Protection standards such as IP65 / NEMA 4X guarantee the unit is dust-tight and protected against water jets, provided it is used with a suitable cable plug.
The Vibration-Proof Coil System features a centrally screwed coil, ensuring stable and secure operation even in harsh industrial environments.
Thanks to its Damped Design for Quiet Closing , the product operates with minimal noise, ideal for noise-sensitive settings.
An Energy-Saving Option , employing Kick-and-Drop (KD) double coil technology, reduces power consumption during use, enhancing efficiency.
A Manual Override Option is available, enabling easy maintenance and commissioning through a user-friendly design.
For applications related to potable water, the Drinking Water Approvals are ensured by its standard brass housing, complying with all European drinking water standards.
For hazardous environments, Explosion-Proof Variants certified by ATEX are offered, suitable for use in potentially explosive atmospheres.
Installation is highly Flexible , allowing the unit to be mounted in any orientation, though it is recommended to keep the actuator upright for optimal performance.
