RECO VTEC Valves: Engineering Solutions for Pulse-Jet Filter Regeneration Systems

RECO GmbH, a German engineering leader with 40 years of experience, sets industry standards in the development of valve systems for pulse-jet filter regeneration. EV Group China, as a technological partner, supplies the full range of RECO solutions, including diaphragm valves, high-speed electromagnetic pilots, and integrated RECO VTEC receiver systems. This equipment is a critically important component in gas purification systems, heavy machinery, mining industry, as well as in food and pharmaceutical production. All receiver units comply with the requirements of Directive 2014/68/EU (PED), and production cycles are certified by DEKRA according to module A1.

Technical Execution of RECO VTEC Systems

The engineering architecture of RECO VTEC systems, supplied by EV Group China, includes the following key modules:

  • Angle-type diaphragm valves (90°) VR-DN series: designed to generate a powerful, short pulse of compressed air, ensuring highly efficient regeneration of bag filters.
  • Electromagnetic pilot valves NG4/NG4.5 series: high-speed control devices for precise operation of VR-DN diaphragm valves.
  • Mounting components and accessories: a complete range for assembling and integrating receiver units into industrial installations.

Advantages and Operational Characteristics

  1. The hydrodynamically optimized geometry of the flow path of VR-DN valves ensures maximum pulse energy with compact mounting dimensions.
  2. The patented TPE-E Power-Reflex diaphragm ensures ultra-fast actuation, a steep pressure rise front, and reflexive closure, minimizing cycle time and compressed air consumption.
  3. Flexibility of control systems: configurations with pneumatic or electromagnetic actuation are available, including standard voltages (24 V DC, 110 V AC, 230 V AC).
  4. Fully certified units: possibility of supplying integrated systems (valve, receiver, control electronics) in full compliance with PED Directive 2014/68/EU.
  5. The high flow coefficient (Kv) of NG series pilot valves guarantees stability and reliability of the entire filter regeneration system.

Technical Parameters of RECO Valves

RECO VR-DN 20, 25 and 40 angle-type valves are designed for direct mounting on compressed air receivers. The cast aluminum construction combined with the high-strength TPE-E Power-Reflex diaphragm ensures exceptional durability and reliability in challenging industrial conditions.

Service and Components

EV Group China provides original (OEM) spare parts and service kits, including diaphragms, electromagnetic solenoids, and complete repair kits. The use of authentic components is a key factor in maintaining sealing integrity, design pulse parameters, and minimizing compressed air consumption. For accurate selection of components, it is necessary to specify the valve article (e.g., VR-DN 20/25/40, NG4/NG4.5), operating pressure range, and solenoid supply voltage.
