Ball Valves :
Ball Valves are of soft seated, Floating Ball,
3 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, and integral part of the
stem, prevents the stem from blowing out
from 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 to ensure low operation torque
and high pressure holding capacity and thus
increasing life of the valve.
Optional Features :
* Single piece & two piece design Ball valves.
in full port & regular port.
* Jacketed construction.
* Hard Crome plated Balls.
* Extra long extended Ball Valves.
