00221871 00221872 00221873 BURKERT G1/2 6281EV A 2/2 Normally Closed 13.0 Flow Hole FKM Sealed Brass Valve Body

Product Description:

The valve utilizes a servo-assisted structure combining a pilot isolation diaphragm with plunger actuation. Its pilot valve is designed as a rotary armature or rocker solenoid valve featuring an isolation diaphragm. This design ensures that the medium does not pass through the pilot orifice, which significantly enhances the valve's resistance to clogging.

Opening: The main diaphragm requires a minimum differential pressure of 0.2 bar to actuate. The pilot valve regulates the pressure inside the main chamber to facilitate valve opening.

Closing: A damped mechanism is incorporated to guarantee a quiet closure without water hammer effects, which minimizes the impact on the pipeline and reduces noise pollution.

Energy Saving: An optional KD dual-coil technology is available, which automatically lowers power consumption during steady-state operation after the initial actuation, making it highly suitable for long-term continuous applications.

Wide Material Compatibility: The valve body can be selected from brass or stainless steel, while sealing materials include NBR, EPDM, and FKM. This variety allows suitability for water, gases, general chemicals, and high-temperature environments.

High Reliability & Durability: Featuring a centrally threaded coil with vibration resistance and an epoxy resin encapsulation that enhances chemical resistance. The pilot isolation diaphragm design effectively reduces the risks of clogging and leakage.

Flexible Customization: Optional features such as manual override for commissioning and maintenance, KD energy-saving coil technology, and explosion-proof certification ensure adaptability to harsh and hazardous environments.

Comprehensive Compliance: The valve meets multiple regulatory standards including drinking water safety, ATEX explosion-proof requirements, and UL/CSA certifications, making it suitable for cross-regional use with demanding compliance needs.

This valve is widely used in municipal and industrial water treatment systems as well as drinking water supply networks. Standard brass models comply with relevant industry standards.

In food and beverage or pharmaceutical liquid preparation systems, stainless steel valves combined with EPDM or FKM seals meet stringent hygiene requirements.

For transfer systems involving compressed air, hydraulic oil, and general chemicals, material selection should be tailored based on the properties of the medium.

The valve is also suitable for fluid control in hazardous areas, with models certified under ATEX and IECEx standards.

Differential Pressure Matching: Ensure the operating differential pressure is at least 0.2 bar; otherwise, the valve may fail to open reliably.

Medium Compatibility: For highly corrosive media, choosing a stainless steel body with FKM seals is recommended. For drinking water applications, the standard brass body with EPDM seals is appropriate.

Working Condition Optimization: Use the KD dual-coil option when continuous operation is expected to reduce energy consumption. Select explosion-proof certified models when working in hazardous environments.

Installation & Maintenance: Install a strainer upstream to prevent impurities from entering the valve. Avoid applying pipe stress to the valve body by providing independent support for the pipeline. The manual override function is intended solely for commissioning and emergency use and should not be employed for prolonged forced valve opening.
