Bürkert 00222122 (6213EV Series) is a 2/2-way servo-assisted normally closed (NC, circuit function A) diaphragm solenoid valve, designed for neutral liquids, gases and vacuum applications. It features a compact structure, high flow rate and low noise, making it ideal for industrial fluid control and water treatment scenarios.
It adopts a semi-direct acting structure with spring-coupled diaphragm + plunger pilot control, where the diaphragm serves both as a seal and an actuator:
- Opening: Spring assistance enables partial opening at zero differential pressure; full opening of the standard liquid version requires minimal differential pressure. The special HP00 model can achieve zero-differential opening, suitable for gas and vacuum applications.
- Closing: Damped design ensures quiet, water-hammer-free closure; the vibration-resistant threaded coil system enhances long-term operational reliability.
- Energy Saving: Optional KD dual-coil technology reduces steady-state power consumption after initial actuation, balancing fast response and low energy consumption.
- Zero-differential Pressure Compatibility: Spring-coupled diaphragm design supports partial opening at zero differential pressure; the HP00 model further meets the zero-differential requirements of gas and vacuum working conditions.
- Quiet & Stable Operation: Damped closing and vibration-resistant coil minimize noise and component wear, extending service life.
- Excellent Material Compatibility: Stainless steel valve body combined with EPDM seal offers strong corrosion resistance, suitable for various industrial media.
- Flexible Customization: Optional KD energy-saving coil and multiple sealing materials (NBR/FKM/EPDM) are available to adapt to different working conditions.
- Water treatment, industrial circulating water and cooling systems.
- Compressed air, neutral gas and vacuum systems (adapted with HP00 model).
- Food, beverage and pharmaceutical equipment (stainless steel + EPDM/FKM seal meets hygiene requirements).
- General industrial fluid on-off control requiring compact installation and high flow rate.
- Media Compatibility: Select sealing material according to media properties (NBR for oil-based media, FKM for chemical-resistant media).
- Working Condition Matching: Specify the HP00 model for gas/vacuum applications; choose the KD dual-coil for long-term continuous operation to reduce energy consumption.
- Installation & Maintenance: Install a strainer upstream to prevent impurities from damaging the pilot valve mechanism; avoid pipe stress on the valve body and support the pipeline independently.
Packing and Shipping:
Product Packaging and Shipping for Burkert Solenoid Valve:
Each Burkert Solenoid Valve is carefully packaged to ensure maximum protection during transit. The valve is first wrapped in anti-static, shock-absorbent material to prevent any damage from impacts or vibrations. It is then placed in a sturdy, custom-designed cardboard box that fits the product snugly, minimizing movement inside the package.
Additional packaging materials such as foam inserts or bubble wrap may be used depending on the size and model of the valve to provide extra cushioning. The box is clearly labeled with handling instructions, product details, and shipping information to ensure proper handling throughout the delivery process.
For international shipments, the packaging complies with all relevant regulations to prevent damage and ensure safe arrival. The product is shipped via reliable carriers, with tracking provided for customer convenience.
Overall, the packaging and shipping procedures for Burkert Solenoid Valves are designed to maintain product integrity, ensuring that customers receive their valves in perfect working condition.
