Being part of the proven KÜHME high-performance valve series for industrial applications, the valve type KVII/F is used in application area for which the quick and safe shut-off of gaseous media and fuels is required. The electro-pneumatically controlled quick-closing valve sets standards in regards to service life and reliability even in the most demanding applications.

Application areas

  • Automatic shut-off valve with pneumatic actuator with fast-close operation in case of breakdown of the auxiliary energy for gas burners and gas appliances with EC-Type-Examination-Certificate in acc. with   Gas Appliances Directive
  • 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
  • As a control element for the fuel mass flow rate to control the combustion performance according to
    DIN EN 12 952-8 para. 4.4.1
  • Combustion systems for liquid and gaseous fuels in accordance with DIN EN 12 953-7
  • Pipe systems for gaseous media and fuels in all industrial sectors
Nominal size: DN 65 to DN 300
Operating pressure: max. 10.0 bar g
Operating temperature: max. + 180°C


  • 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 life

The quick-closing valve is actuated by a pneumatic actuator with a solenoid control valve. Automatic quick-closing is carried out by the installed spring force in less than 1 second. The valve cone with soft sealing element guarantees absolute tightness (leakage rate A in acc. with EN 12266-1).
