G3/8 Thread Normally Open Servo‑operated Solenoid Valve Burkert 6281 Series DN13 Orifice Brass Valve Housing NBR Nitrile Rubber Seal Multiple Coil Voltage Options 00221923 00221924 00221925

Product Description:

The Burkert 6281 series is a servo-assisted 2/2-way diaphragm solenoid valve specifically engineered for dependable shut-off, precise dosing, and efficient filling of neutral gaseous and liquid media. Common applications include compressed air and water. For proper operation, the valve requires a minimum differential pressure to function effectively.

This valve is equipped with a vibration-proof coil system that is centrally screwed, ensuring durability and stability during use. Additionally, its damped design allows for quiet closing, minimizing noise in the working environment. The solenoid coils are encapsulated with chemically resistant epoxy, enhancing their longevity and resistance to harsh conditions.

To optimize energy efficiency, variants with electronic power reduction coils are available, significantly lowering power consumption during operation. The valve’s standard housing is made from brass that complies with all European drinking water standards, including KTW/W270. For markets requiring enhanced corrosion resistance, dezincification-resistant brass housing options are offered.

Maintenance and commissioning are simplified through an optional manual override feature, which is designed to be service-friendly. When paired with a suitable cable plug conforming to DIN EN 175301-803 Form A, the valve achieves an IP65 protection rating, ensuring protection against dust and water ingress. The valve’s design permits installation in any position, although positioning the actuator upright is recommended for optimal performance.

Features:

The servo-assisted diaphragm design ensures dependable performance for shut-off, dosing, and filling tasks involving neutral media. This design enhances the reliability of valve operations in various industrial applications.

Featuring a normally open (NO) configuration with circuit function B, the valve remains open in the event of power loss. This fail-open functionality is crucial for applications where continuous flow is necessary during de-energized states.

Constructed from durable brass, the valve body offers excellent corrosion resistance and a prolonged service life, making it well-suited for demanding environments. The use of NBR seal material supports dependable operation within a temperature range of -10°C to +80°C.

A wide selection of port and orifice sizes is available, ranging from G1/4 to G2 ports and 10 mm to 50 mm orifices. This flexibility allows the valve to accommodate a broad spectrum of flow requirements across different applications.

The valve operates efficiently across a pressure range of 0.2 bar up to 16 bar. Standard 8W coils enable a 100% continuous duty cycle, ensuring reliable long-term performance without overheating.

Multiple voltage options are offered, including DC24V, AC24V, and AC220V, all with a tolerance of ±10%. This variety facilitates compatibility with electrical systems worldwide.

Designed with an IP65 protection rating, the valve is dust-tight and safeguarded against water jets when used with an appropriate cable plug. Additionally, the vibration-proof coil system, secured by a central screw, guarantees stable operation even in harsh industrial settings.

The valve employs a damped design for quiet closing, minimizing noise in sensitive environments. An energy-saving Kick-and-Drop (KD) double coil technology further reduces power consumption during operation.

For ease of maintenance and commissioning, a manual override option is provided, allowing service-friendly control. The standard brass housing complies with all European drinking water regulations, ensuring safe use in potable water systems.

Explosion-proof variants with ATEX certification are available for applications in hazardous areas. The valve’s flexible installation design permits mounting in any orientation, although an upright actuator position is preferred for optimal performance.
