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 specifically engineered to provide dependable shut-off, dosing, and filling functions for neutral gaseous and liquid media. This valve is constructed with a stainless steel body combined with an EPDM (ethylene-propylene-diene rubber) seal, which delivers excellent resistance to corrosion as well as flexibility at low temperatures, making it well-suited for challenging industrial environments.
For proper operation, the valve requires a minimum differential pressure. Its coil system is vibration-resistant and centrally screwed, featuring a damped design that guarantees quiet closing and extends the valve’s service life. The standard model uses a brass housing that complies with all relevant European drinking water standards (KTW/W270). Additionally, dezincification-resistant brass versions are available for other international markets, complemented by a stainless steel variant to meet varied application needs.
To improve energy efficiency during operation, the valve offers coils equipped with "Kick and Drop" (KD) electronics, utilizing double coil technology to reduce power consumption. Maintenance and commissioning are simplified through an optional manual override feature. When paired with a suitable cable plug conforming to DIN EN 175301-803 Form A, these valves achieve an IP65 protection rating. Furthermore, with a stainless steel housing, they meet the stringent NEMA 4X standard for protection against environmental factors.
Installation is flexible, allowing the valve to be mounted in any position. However, it is recommended to position the actuator upright to ensure optimal functionality and longevity.
Features:
The valve features a robust stainless steel body construction, ensuring excellent corrosion resistance. This makes it ideal for use with aggressive media and in demanding environmental conditions.
Equipped with an EPDM (Ethylene-Propylene-Diene Rubber) seal, the valve offers outstanding resistance against water, dilute acids, alkalis, and various other media. It supports a media temperature range from -30°C up to +90°C, which can be extended to +100°C when using an epoxy coil.
Its servo-assisted diaphragm design guarantees reliable operation, suitable for shut-off, dosing, and filling tasks involving neutral and mildly aggressive media. Additionally, the normally closed (NC) configuration with circuit function A delivers fail-safe operation, catering to critical process control requirements.
The product provides a wide selection of port sizes ranging from G1/4 to G2, along with orifice sizes between 10 mm and 40 mm. This variety ensures compatibility with diverse flow demand scenarios. It can handle pressures from 0.2 bar up to 16 bar.
Standard 8W coils enable a 100% continuous duty cycle, promoting reliable and long-term functionality. Multiple voltage options are offered, including DC24V, AC24V, and AC220V, each with a ±10% tolerance, ensuring compatibility across global electrical standards.
With an IP65 / NEMA 4X rating, the valve is dust-tight and protected against water jets, provided it is used with the appropriate cable plug. The vibration-proof coil system features a centrally screwed coil, allowing secure operation in challenging industrial environments.
The design incorporates damping to achieve quiet closing, which is beneficial in noise-sensitive settings. An energy-saving feature, the Kick-and-Drop (KD) double coil technology, helps reduce power consumption during use.
Maintenance and commissioning are simplified by a service-friendly manual override option. The valve’s standard brass housing complies with all European drinking water standards, making it suitable for potable water applications.
For hazardous area usage, explosion-proof variants with ATEX certification are available. Installation is flexible, as the valve can be mounted in any position, although it is preferred to have the actuator oriented upright.
