QUICK-CLOSING VALVE IN DOUBLE SEAT DESIGN
TYPE KVII/FD

Being part of the proven KÜHME high-performance valve series for industrial applications, the KÜHME valve type KVII/FD in angle design with double-seat feature is used in any application area for which the quick and safe shut-off of low calorific gaseous fuels such as, e.g., coke oven gas is required. The electro-pneumatically controlled quick-closing valve sets standards for lifetime and reliability even in most demanding applications.

Application areas
  • Quick acting safety shut-off valve for gaseous fuels, gas-burners and gas appliances with EC-Type-Examination (Module B) in acc. with PED
  • Automatic shut-off valve in pipe systems in accordance with DIN EN 746-2 Industrial thermo-processing equipment
  • Pipe systems for gaseous media and fuels in all industrial sectors
Nominal size: DN 200 to DN 400
Operating pressure: max. 1.2 bar g
Operating temperature: max. + 180°C

Advantages
  • Closing time < 1 second
  • High safety level through zero leakage
  • Heavy duty design for high amount of operating cycles
  • High-performance valve with a long service lifetime
Function
The quick-closing valve is actuated 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. The soft seal at the valve cone guarantees absolute tightness (leakage rate A in acc. with EN 12266-1).
