00221862 6281EV Solenoid Valve DN40 BURKERT G1 1/2 2/2 is usually closed

Product Description:

This valve features a servo-assisted design utilizing a pilot isolation diaphragm combined with plunger actuation. The pilot valve functions 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 provides excellent resistance to clogging.

When opening, 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.

During closing, a damped mechanism guarantees a quiet and water-hammer-free shutoff, minimizing pipeline impact and reducing noise pollution.

For energy efficiency, an optional KD dual-coil technology is available, which automatically lowers power consumption after the initial actuation. This feature is ideal for applications requiring long-term continuous operation.

The valve body is offered in both brass and stainless steel options, with sealing materials including NBR, EPDM, and FKM, making it compatible with water, gases, various chemicals, and capable of handling high-temperature conditions.

High reliability is ensured through the use of a centrally threaded coil with vibration resistance and epoxy resin encapsulation for chemical protection. Additionally, the pilot isolation diaphragm reduces the risk of clogging and leakage.

Flexible customization options include a manual override for commissioning and maintenance purposes, KD energy-saving coil, and explosion-proof certifications. These features make the valve suitable for challenging and hazardous environments.

The product complies with multiple standards such as drinking water regulations, ATEX explosion-proof requirements, and UL/CSA certifications, enabling its use across different regions with stringent regulatory demands.

Common uses include municipal and industrial water treatment systems as well as drinking water supply systems, where standard brass models meet relevant standards.

The valve is also applicable in food and beverage industries and pharmaceutical liquid preparation systems, utilizing stainless steel bodies with EPDM or FKM seals to satisfy hygiene requirements.

It can serve in transfer systems for compressed air, hydraulic oil, and general chemicals, with material selection tailored to the specific properties of the medium.

Furthermore, fluid control in hazardous areas is supported with models certified under ATEX and IECEx standards.

When selecting this valve, ensure the working differential pressure is equal to or greater than 0.2 bar to guarantee reliable opening.

Medium compatibility should guide material choice: stainless steel body with FKM seals is recommended for highly corrosive media, whereas standard brass bodies with EPDM seals are suitable for drinking water applications.

For optimized working conditions, consider KD dual-coil options to reduce energy consumption in continuous operation scenarios. Explosion-proof certified models must be specified when deploying in hazardous areas.

During installation and maintenance, it is advised to install a strainer upstream to prevent impurities from entering the valve. Avoid applying pipe stress on the valve body by independently supporting the pipeline. The manual override should only be used for commissioning and emergency situations, and must not be employed for prolonged forced openings.
