Gas flow control valve SVL


The SVL flow control valves are used to adjust the flow rate of gas and cold air in gas and air consuming appliances.

The SVL flow control valves operate with a rotatable cylinder for volume control. The control cylinder is designed for an approximately linear relationship between volume flow and opening angle. Depending on the opening angle between 0° and 90°, a different cross-section is released for the medium. The currently set opening angle can be read off via an integrated position indicator. The control valves are available in seven different sizes. Installation is carried out via either Rp or NPT threaded connections in several gradations from ½” to 2″ pipe diameter.
