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

Data sheet

Application areas

  • Automatic shut-off valve within steam pipe systems in all industrial areas
Nominal size: DN 15 to DN 50
Operating pressure: max. 40.0 bar g
(depending on the operating temperature)
Operating temperature: max. + 400°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. Absolute tightness (leakage rate A in acc. with EN 12266-1) is guaranteed long term by means of the specially machined valve cone and a 4/2-way  control via solenoid valve.
