Ball valves are used as shut-off valves in heating and water supply systems, steam, fuel, and pneumatic systems with compressed air and neutral gases. Valves of this series can be installed in systems transporting liquid and gaseous media (water, oil, steam, air, alcohols, glycol, etc.) that are non-corrosive to the valve materials. Ball valves are not permitted for use as control valves.
PA-DA-x double-acting pneumatic actuators use two ports to supply the control fluid and create movement in both directions, both for opening and closing the valve. One port is used to move the piston in one direction, and the other to move it in the opposite direction.
