Ball
Valves :
Ball Valves are of soft seated, Floating Ball, 3 piece
design available in both Regular
port & Full Port patterns. Ball is seat suppported 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.
