Operating principle is based on dilution of hot gas-and-dust stream by atmospheric air, which happens due to injecting when opening this valve.
Emergency valve is louvered type. It has louver, with common drive from pneumatic cylinder. Pressure supply to pneumatic cylinder is achieved by means of specially selected high-speed pneumatic distributors, which receive signal from thermal sensor and control system. The valve is equipped with filter, which regulates compressed air and serves for its cleaning from drop moisture and dust and also for pressure restriction over 6 bar.
The main advantage of this design is its reaction (response) speed 1-2 seconds that is extremely important for protection of bags against temperature jumps.
Valve dimensions depend on the necessary dilution temperature of the flow and are calculated by specialists of our company.
Mounting of the valve is carried out both at horizontal and vertical site of a gas flue by means of flange connections.
In addition, our company can develop design drawing of the emergency valve for the most non-standard inquiries. GUARANTEE FOR EMERGENCY VALVES IS 12 MONTHS.
