QUICK-CLOSING VALVE COMBINATION TYPE KVII/F-KVII/F In view of the requirements of the European laws and regulations, KÜHME offers the proven high-performance valve series as double block and Bleed unit with intermediate ventilation, completely ready for installation. The quick-closing valves combine the core competencies of KÜHME in valve technology with those of a system supplier for plant installations tailored to the demand. The first valve can be designed as combined quick-closing control valve with type examination. This renders unnecessary the installation of a separate control valve. The individually adapted control behaviour leads to an optimised burner operation. Applications: Thermal Power Plants, Gas Turbines, Biogas & Landfill Gas, Pipeline & Gas Distribution Systems, Industrial Combustion YOUR BENEFITS Closing time < 1 second Safety due to absolute tightness Optionally available as quick-closing control valve combination Heavy duty design for high operating cycles High-performance valves for long lifetime Pre-mounted component, completely ready for installation H2-ready OPERATION DETAILS The quick-closing valves are operated each via a pneumatic actuator with a solenoid control valve. Automatic quick-closing is carried out by means of spring force in less than 1 second. At the same time, the intermediate ventilation valve type KEV opens within 1 second and relieve the gas volume between the closed quick-closing valves. The soft seal attached at the valve cone guarantees absolute tightness (leakage rate A in acc. with EN 12266-1).
