00221856 Burkert 6281EV A25.0 NBR G1 24VDC DN25 00221857 00221858

Product Description:

This valve utilizes a servo-assisted design featuring a pilot isolation diaphragm combined with plunger actuation. The pilot valve is constructed as a rotary armature or rocker solenoid valve equipped with an isolation diaphragm, ensuring that the medium does not pass through the pilot orifice. This design offers excellent resistance to clogging.

For opening, a minimum differential pressure of 0.2 bar is necessary to actuate the main diaphragm. The pilot valve manages the pressure within the main chamber to facilitate the valve’s opening. When closing, a damped mechanism guarantees a quiet shutdown without water hammer effects, minimizing pipeline impact and noise pollution.

Additionally, the valve supports energy-saving features through the optional KD dual-coil technology, which automatically lowers power consumption once initial actuation is complete. This makes it particularly suitable for long-term continuous operation scenarios.

The valve is compatible with a broad range of materials. The body can be constructed from brass or stainless steel, while sealing options include NBR, EPDM, and FKM. This versatility makes the valve ideal for use with water, gases, general chemicals, and under high-temperature conditions.

Reliability and durability are enhanced by a centrally threaded coil design that resists vibration and an epoxy resin encapsulation that provides chemical resistance. The pilot isolation diaphragm further reduces the likelihood of clogging and leakage.

Flexibility in customization is also available. Options include manual override for commissioning and maintenance, KD energy-saving coils, and explosion-proof certifications. These features allow the valve to be adapted for use in demanding and hazardous environments.

Compliance is comprehensive, with conformity to drinking water standards, ATEX explosion-proof norms, and UL/CSA certifications. This ensures the valve meets stringent regulatory requirements across different regions.

The valve is widely used in municipal and industrial water treatment systems, as well as drinking water supply networks. Standard brass variants comply with relevant standards for potable water.

In the food and beverage industry, as well as pharmaceutical liquid preparation, stainless steel bodies combined with EPDM or FKM seals satisfy strict hygiene demands.

It is also applicable in transfer systems for compressed air, hydraulic oil, and various chemicals, with material selection tailored to the properties of the medium.

For fluid control in hazardous areas, models certified under ATEX or IECEx standards are available.

When selecting the valve, ensure that the working differential pressure is at least 0.2 bar; otherwise, reliable valve opening cannot be guaranteed.

Medium compatibility should be considered carefully: use stainless steel bodies with FKM seals for highly corrosive media, and standard brass with EPDM seals for applications involving drinking water.

For optimized operation, choose the KD dual-coil option when continuous use is expected to reduce energy consumption. In hazardous environments, specify explosion-proof certified models.

Installation requires an upstream strainer to block impurities from entering the valve. Care must be taken to avoid pipe stress on the valve body by independently supporting the pipeline. The manual override function is intended solely for commissioning and emergency situations and should not be used for prolonged forced opening.
