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 reliable shut-off, dosing, and filling functions for neutral gaseous and liquid media. The valve’s construction includes a stainless steel body combined with an EPDM (ethylene-propylene-diene rubber) seal, which ensures outstanding corrosion resistance and flexibility at low temperatures, making it suitable for demanding industrial environments.
To operate effectively, the valve requires a minimum differential pressure. Its design incorporates a vibration-resistant, centrally screwed coil system with damping features, resulting in quiet closing and an extended service life. The valve features a standard brass housing that complies with all European drinking water standards (KTW/W270). For markets requiring enhanced durability, a version with dezincification-resistant brass is also available. Additionally, a stainless steel variant is offered to meet diverse application needs.
For improved energy efficiency during operation, coils equipped with "Kick and Drop" (KD) electronics, which utilize double coil technology, can be supplied. The valve can also be fitted with a manual override, facilitating easy maintenance and commissioning procedures. When paired with a compatible cable plug conforming to DIN EN 175301-803 Form A, these valves achieve an IP65 protection rating. Moreover, the stainless steel housing option elevates the protection class to NEMA 4X.
Installation of the valve can be performed in any orientation, although it is preferable to position the actuator in an upright manner to optimize performance.
Features:
Stainless Steel Body Construction
The stainless steel body offers outstanding corrosion resistance, making it ideal for use with aggressive media and in challenging environments.
EPDM Seal
The EPDM (Ethylene-Propylene-Diene Rubber) seal ensures excellent resistance against water, dilute acids, alkalis, and various other media. It functions effectively within a temperature range of -30°C to +90°C, extending up to +100°C when equipped with an epoxy coil.
Servo-Assisted Diaphragm Design
This design guarantees dependable operation for shut-off, dosing, and filling processes involving neutral and mildly aggressive media.
Normally Closed Configuration
The circuit function A (Normally Closed) setup provides fail-safe operation, meeting essential requirements for process control applications.
Wide Port and Orifice Range
Port sizes vary from G1/4 to G2, and orifice sizes range between 10 mm and 40 mm, allowing for customization to different flow demands.
Wide Pressure Range
The system operates efficiently under pressures from 0.2 bar up to 16 bar.
Standard 8W Coils
Standard coils rated at 8 watts provide a 100% continuous duty cycle, ensuring reliable, long-term usage.
