DME Company Datasheets for Ball Valves
Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that rotates to open and close the valve. Ball valves are used in situations where tight shut-off is required. They are wide duty valves, able to transfer gases, liquids and liquids with suspended solids (slurries).
Ball valves provide tight shut-off and characterizable control. They have high rangeability due to the design of the regulating element and few complications from side loads typical of butterfly or globe valves.
