00221864 00221863 00221862 BURKERT 6281 type G1 1/2 2/2 normally closed 40.0 flow hole NBR sealed brass valve body

Product Description:

The valve utilizes a servo-assisted design featuring a pilot isolation diaphragm combined with plunger actuation. The pilot valve incorporates a rotary armature or rocker solenoid valve equipped with an isolation diaphragm, which ensures that the medium does not flow through the pilot orifice. This design significantly enhances its resistance to clogging.

During the opening phase, a minimum differential pressure of 0.2 bar is necessary to activate the main diaphragm. The pilot valve regulates the pressure within the main chamber to facilitate valve opening. When closing, a damped mechanism ensures that the valve shuts quietly, eliminating water hammer effects and minimizing pipeline stress and noise pollution.

For energy efficiency, an optional KD dual-coil technology is available. This feature automatically reduces power consumption during steady-state operation after the initial actuation, making it well-suited for applications that require long-term continuous use.

This valve offers wide material compatibility with options for the valve body made from brass or stainless steel. The sealing materials include NBR, EPDM, and FKM, making it adaptable for use with water, gases, various chemicals, and under high-temperature conditions.

It boasts high reliability and durability, featuring a centrally threaded coil that provides vibration resistance and epoxy resin encapsulation for chemical resistance. The pilot isolation diaphragm design further minimizes risks associated with clogging and leakage.

Flexible customization options include an optional manual override for commissioning and maintenance, KD energy-saving coils, and explosion-proof certifications. These options enhance its suitability for demanding and hazardous environments.

In addition, the valve complies with multiple industry standards such as drinking water regulations, ATEX explosion-proof requirements, and UL/CSA certifications, ensuring compatibility with stringent cross-regional regulatory frameworks.

The valve is widely used in municipal and industrial water treatment systems as well as drinking water supply networks, with standard brass models conforming to relevant regulatory standards.

It is also suitable for the food and beverage industry and pharmaceutical liquid preparation systems, where the combination of stainless steel and EPDM or FKM seals meets strict hygiene standards.

Additionally, the valve supports transfer systems for compressed air, hydraulic oil, and general chemicals, with material selections tailored to the properties of the medium in use.

For fluid control in hazardous areas, models certified by ATEX or IECEx provide safe and reliable operation.

When selecting this valve, ensure that the working differential pressure is at least 0.2 bar to guarantee reliable valve opening.

For media with strong corrosive properties, choose a stainless steel valve body combined with an FKM seal. For drinking water applications, the standard brass body with EPDM seals is recommended.

To optimize working conditions, the KD dual-coil option is preferred for continuous operation to reduce energy consumption. Explosion-proof certified models should be specified for use in hazardous environments.

Proper installation and maintenance practices include placing a strainer upstream to prevent impurities from entering the valve, avoiding stress on the valve body by independently supporting the pipeline, and limiting the use of the manual override to commissioning or emergency situations only; it should not be used for prolonged forced valve opening.
