Whether used with gate valves, globe valves, penstocks or sluice gates, versatile L120 Series actuators operate without modification in any rising or non-rising stem application for linear-action valves. When combined with a Limitorque WG or HBC series quarter-turn gear operator, L120 actuators can also be used to control butterfly, ball and plug valves, as well as damper drives, flop gates or any other device which requires rotary movement.
