Ball Valves
Reliable Valves offers a range of Ball Valves. These valves have a spherical ball that moves in a plane perpendicular to the direction of flow. Full opening through ball valves shall have a circular bore in the spherical ball that allows a sphere to pass with a nominal size not less than ½†nominal diameter. Reduced opening through ball valve shall have a semi circular bore in the spherical ball that allows a sphere to pass with a nominal size not less than 10" nominal diameter, unless otherwise specified by customer. Reduced opening valves with non-circular opening through the spherical ball shall be supplied with a minimum opening as agreed by customer.
