Product Description:
The Burkert 6281 series belongs to the S.EV series and is a servo-assisted 2/2-way diaphragm solenoid valve. It is engineered to provide reliable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media. Constructed with a stainless steel body combined with an EPDM (ethylene-propylene-diene rubber) seal, this valve delivers outstanding corrosion resistance as well as excellent flexibility at low temperatures, making it suitable for demanding industrial environments.
For proper operation, the valve requires a minimum differential pressure. Its vibration-resistant coil system, secured centrally with screws, alongside a damped design, ensures quiet closing and enhances the valve's durability. The standard brass housing meets all European drinking water standards (KTW/W270), while a dezincification-resistant brass variant is offered to meet the requirements of other markets. Additionally, a stainless steel version is available for further versatility.
To optimize power consumption, the valve can be equipped with coils featuring "Kick and Drop" (KD) electronic assemblies, which utilize double coil technology. Maintenance and commissioning are simplified with the option of a manual override. When used with an appropriate cable plug conforming to DIN EN 175301-803 Form A, the valves achieve an IP65 protection rating. Moreover, combining the valve with a stainless steel housing elevates the protection class to NEMA 4X.
Installation flexibility is another advantage of the Burkert 6281 series, as the valve can be mounted in any orientation, though it is recommended to position the actuator upright for optimal performance.
Features:
Stainless Steel Body Construction
The body is crafted from stainless steel, delivering outstanding corrosion resistance. This makes it ideal for use with aggressive media and in demanding environmental conditions.
EPDM Seal
The seal is made from EPDM (Ethylene-Propylene-Diene Rubber), which offers excellent durability against water, dilute acids, alkalis, and various other substances. It can withstand media temperatures ranging 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 dependable operation for functions such as shut-off, dosing, and filling when handling neutral or mildly aggressive fluids.
Normally Closed Configuration
The circuit functions in a normally closed (NC) mode, providing fail-safe operation suitable for precise process control requirements.
Wide Port and Orifice Range
Available port sizes range from G1/4 to G2, with orifice sizes spanning from 10 mm to 40 mm. This wide range accommodates various flow demands.
Wide Pressure Range
The device operates efficiently across a broad pressure range, from 0.2 bar up to 16 bar, providing versatility in different applications.
Standard 8W Coils
