Valve Type & Configuration

Ball valves shall 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. Reduce opening through Ball valve shall have a semi circular bore in the spherical ball that allows a phere to pass with a nominal size not less than 10" nominal diameter, Unless otherwise specified by customer.

Reduce opening valves with a non circular opening through the spherical ball shall be supplied with a minimum opening as agreed by customer.
