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.
Pressure & Temperature Rating Valves manufactured shall be furnished in one of the following classes
PN 20 (class 150)
PN 50 (class 300)
PN 64 (class 400)
PN 100 (class 600)
PN 150 (class 900);
PN 250 (class 1500)
PN 420 (class 2500);
Pressure-temperature rate is for above class rated valves shall be in accordance to ASME-B 16.34/EN 1092-1, Other than shall be determine for a material properties in accordance with the applicable design standard.
