BALL VALVES :
 

"SEW" Ball valves are of soft seated, Floating Ball.  Three piece design available in both regular port & full port patterns.  Ball is seat supported and quarter turn rotates the ball from full open to full close position.
The Stem Flange, on entire part of the stem, prevents the stem from blowing out pressure within the body cavity.  This feature also allows replacement of stem packing while the valve is under pressure.

One of the most important component in any Ball valve is the Ball itself.  The Ball is accurately machined to mirror finish and the exact sphericity so as to ensure low operating forque and high pressure holding capacity and thus increasing life the valve.
