GUIDE LEVER VALVES
GUIDE LEVER VALVES
The VCL Guide Lever Valve is a gastight shut-off valve for gaseous media. Due to the internal lever arrangement, only very low friction appears between valve seat and the valve plate while operating. That leads to a long lifetime, even at high operating frequency. The main fields of application are the Iron & Steel industry, air separation units, gas-fired power plants, the chemical industry, and other plants, where gaseous media have to be isolated and the valve is operated under quite low differential pressures (up to approx. 200mbar), whereas static pressure in opened or closed position can be higher.
