ON / OFF VALVES

ON / OFF VALVES

On/off valves shuts off the flow and remains tight in the flow direction. They offer great tightness when closed and a low flow resistance in the open position. Somas on/off-valves usually come equipped with a pneumatic actuator that can be either single- or double-acting.

Several valves can be used as On/Off’s

Somas offers several different valves that can be used for on/off applications. Our full-bore ball valve SKV offers very low resistance when open and excellent tightness in both flow directions when closed.

Somas butterfly valve is also offered as an on/off valve, it features a “no maintenance required” design and offers superior tightness when closed. Its relatively small size and equally small prize point are other advantages.

Somas ball segment valve is primarily considered a control valve. It can however be used as an on/off valve if desired. Thanks to its openness in terms of flow and it’s more than generous price it is a very good candidate for an on/off valve.
