Engineering overview of Intensiv Filter pulse valves for aspiration systems

Operation principle and construction of Intensiv Filter valves

Intensiv pulse valves are precision electromagnetic diaphragm devices designed for pulse-jet regeneration systems (Jet-Pulse) of bag filters. Their key function is to generate a short and powerful pulse of compressed air, which effectively removes the dust layer from the surface of the filter elements. The valve is controlled via a pneumatic circuit, and airtightness in the closed state is ensured by an elastomeric diaphragm pressed by a return spring. This design guarantees instant response and high reliability in industrial conditions.

The German brand Intensiv Filter is a recognized technological leader in industrial aspiration and air purification from fine particulate matter. The company specializes in designing bag filters with pulse-jet cleaning for the most demanding industries: metallurgy, cement, chemical, and energy. Intensiv Filter solutions aim to achieve maximum filtration efficiency with minimal compressed air consumption.

Integration into ProJet and ProJet Smart cleaning systems

These valves are an integral component of highly efficient pneumatic regeneration systems ProJet and ProJet Smart. They are integrated into the manifold blocks of filtration units, including the Projet Mega Process Filter, ProJet CIP Filter, and CombiJet series. The configuration, quantity, and sizes of the valves are selected individually at the design stage, based on aerodynamic calculations and the performance requirements of a specific aspiration unit.

Key engineering advantages

• Flow optimization: Integration with Coanda injector systems optimizes air flow distribution, reducing overall compressed air consumption by 15-20%.
• Precision control: High accuracy of pulse control via the JetBus controller with adaptive adjustment of blow-off parameters (duration, interval) in real-time.
• Serviceability: Modular design allows for servicing and replacement of key components (diaphragm, solenoid) without disassembling the valve body from the manifold.
• Reliability guarantee: The availability of original spare parts and repair kits from EV Group China guarantees the maintenance of the system's operational characteristics at factory level throughout its entire service life.

Maintenance and component base

EV Group China offers a full range of original components for Intensiv Filter pulse valves. For planned and repair maintenance, both individual components and complete repair kits are available. These include diaphragms of sizes C41, C80, C50, C52, as well as springs and sealing elements. The use of original spare parts allows for the complete restoration of the valve block's performance without the need for its full replacement, which significantly reduces operating costs and equipment downtime.

Where we apply

Intensiv Filter pulse valves are a critical element of aspiration systems in the following industries:

• Metallurgy: Gas cleaning systems for blast furnaces, steelmaking (EAF, converters), and sintering plants. Aspiration of bulk material transfer points.
• Cement industry: Purification of exhaust gases from rotary kilns, clinker coolers, cement and raw material mills.
• Energy: Dust collection units for boilers operating on coal and other solid fuels (CHP, TPP).
• Chemical industry: Aspiration of reactors, dryers, mixers, where fine toxic or explosive dust is generated.
• Mining industry: Dust suppression systems at crushing and screening complexes and beneficiation plants.

How to replace / analogues

Direct replacement of Intensiv Filter valves with analogues from other manufacturers (e.g., Goyen, ASCO, Mecair, Turbo) requires careful engineering analysis. When selecting an analogue, the following parameters must be considered:

• Connection dimensions: Nominal bore diameter (DN) and type of connection (threaded, flanged, integrated into the manifold).
• Operating pressure: The range of compressed air pressures for which the valve is designed.
• Diaphragm material: Selected depending on the temperature and chemical composition of the gas (standard – NBR, for high temperatures – Viton, for aggressive media – EPDM).
• Solenoid electrical characteristics: Voltage (AC/DC) and power must match the parameters of the control controller.
• Response time: The speed of valve opening and closing is critical for forming the correct pulse.

Incorrect selection of an analogue can lead to reduced cleaning efficiency, increased compressed air consumption, and premature failure of both the valve and the filter elements.

What to clarify with the supplier

Before purchasing Intensiv Filter valves or repair kits from a supplier, an engineer or procurement specialist is recommended to request the following information and documentation:

• Certificate of Origin: Confirms that the product is original.
• Product passport: Contains precise technical specifications, including serial number and date of manufacture.
• Article confirmation: Ensure that the article number of the ordered valve or repair kit fully matches the specifications of your equipment.
• Material certificate for the diaphragm: For critical applications, request confirmation of the elastomer material (e.g., Viton) and its temperature range.
• Storage period and conditions: Clarify recommended storage conditions, especially for rubber products (diaphragms), to avoid their premature aging.
• Availability in stock: Request information on stock levels to plan future purchases and minimize downtime.
