The quick-closing valves are operated by 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).
