Industrial AUTEL Valves: Engineering Overview and Classification for Aspiration Systems
Industrial AUTEL valves represent engineering solutions developed for critically important applications in aspiration systems and high-precision dust collection. The products are used in key industries: heavy machine building, metallurgical complexes, cement production, and the chemical industry.
The EV Group China product range includes key components for building high-performance industrial filtration systems:
- Diaphragm pulse valves designed for regeneration (blow-off) systems of bag filters. Full interchangeability with Goyen, Asco, Mecair valves is ensured.
- Solenoid valves and pilot blocks, providing precise control of compressed air flows in automation systems.
- High-tech diaphragms and service kits for scheduled maintenance and restoration of valve operational characteristics.
- Programmable controllers and timers for optimizing pulse cleaning cycles of filtering elements and reducing compressed air consumption.
Key characteristics of AUTEL valves are high operational life and stability of parameters in harsh industrial conditions, including abrasive environments and temperature fluctuations.
Technical Classification of AUTEL Valves
Electromagnetic Valves ensure high-speed compressed air supply. They are equipped with solenoid coils with nominal voltages of 24V, 110V, and 220V for direct integration into industrial SCADA systems.
Pneumatic Valves are used in circuits with external pneumatic control. They guarantee reliable operation in conditions of power outage or in explosive environments (ATEX), ensuring increased reliability.
Two-stage Solenoid Valves are equipped with a double diaphragm design. This engineering solution minimizes hydraulic shocks, extends diaphragm life, and optimizes compressed air consumption by the system.
Pilot valves are designed for centralized control via distribution boxes, ensuring synchronization of pulses in multi-section filtration units to maintain stable performance.

Engineering Advantages of AUTEL Valves
- Peak cleaning (regeneration) performance of filtering elements due to optimized aerodynamics.
- Extended service interval, achieved through the use of elastomers with increased wear resistance and chemical inertness.
- Seamless integration into existing aspiration systems thanks to standardized connection dimensions.
- Simplified installation and maintenance, not requiring specialized tools.
Frequently Asked Questions (FAQ)
What is the fundamental difference between a solenoid and a pneumatic valve actuator?
Solenoid valves use an electrical signal for direct control, which is ideal for automated systems. Pneumatic valves are activated by external air pressure, which is critical for explosive zones (ATEX) and systems without access to an electrical network, ensuring increased reliability.
What functional task does the two-stage design solve?
The two-stage scheme (pilot and main valve) allows controlling a large flow with a low-power solenoid. This reduces the mechanical load on the diaphragm during opening, dampens peak pressure, and significantly increases the operational life of the entire assembly.
Is valve operation allowed in high-temperature environments?
Yes. When equipped with a fluoroelastomer (Viton/FKM) diaphragm, the valves maintain full functionality and tightness at operating medium temperatures up to +150 °C, allowing their use in metallurgy and the cement industry.
What is the periodicity of routine technical maintenance?
When using original AUTEL components, routine replacement of wear parts (diaphragms, springs) is recommended every 12–24 months. The exact interval depends on the intensity of cleaning cycles and the chemical composition of the operating medium.
