FloSource has been automating quarter-turn and multi-turn valves since 2004. We have virtually automated every kind of valve including but not limited to: butterfly, ball, plug, gate, globe, damper, diaphragm, and knifegate valves. We have extensive experience with pneumatic, hydraulic, and electric actuators.  Looking for a certain brand/manufacturer, we can help.  From big to small, we can automate them all.
