Gland
bush prevents stem Galling. |
|
|
The
stem is inserted in the body and back seated through & PIFE rings
against the body wall.The gland is fully piloted in the body and the
stem is a close fit inside the gland.The design assures full support
of the stem at all times. |

|
Every
precaution has been taken to protect the stem seal against damage or
loosening due to mechanical forces. |
|
|
A
fillet relief is accurately machined on the lip of the ball part, permitting
the ball to snap into the open position in perfect alignment snugly
against the Teflon seat. In this position the reduced compressive force
on the seats helps to minimize the possibility of cold-flow of the Teflon
rings and extends service life. |
|
|
R-square
ball valves achieve leak tight sealing even at low pressures by means
of accurately controlled squeeze on the seat rings and ball. |
