Contromatics
Two Piece
Ball Valves
|
 The
Contromatics two-piece-construction
ball valves are standard port valves
that yield optimum performance at a
reasonable cost. The same engineering
design criteria and safety factors that
are utilized in other Contromatics valves
for more critical service applications
are standard in this general
industrial valve. These important safety
and performance-related features combine
to make the Contromatics two-piece ball
valve a truly cost-effective solution
to many of today's most demanding chemical,
petro-chemical, pulp and paper, textile,
OEM and general industrial applications. |

Design Features & Benefits
Bottom
Entry Stem
As safety is of primary concern,
Contromatics utilizes a bottom
loaded stem in all ball valves.
The stem is retained by a machined
shoulder in the body of the
valve that mates up to a shoulder
on the stem. |

Stem
Sealing Method
A critical component of any
valve is its stem sealing capability.
Unlike many of our competitors,
at Contromatics we exclusively
employ a "packing gland"
style stem seal design. The
Contromatics stem seal provides
a compression force independent
from the stem rotation. |
Ball
Construction
Every Contromatics Industrial
valve is of a solid ball construction,
which provides structural integrity
and reduced flow turbulence
not available when "hollow"
or formed balls are used.
There is a hole in the stem
slot of each ball to equalize
pressure between the body cavity
and the flow stream. This feature
prevents seat damage due to
thermal cycling by allowing
media trapped within the body
cavity (between the outside
of the ball and the inside of
the body) to expand and re-enter
the general flow stream through
that drilled hole when the valve
is in the open position. |
Optional
Seat Materials
Contromatics offers a variety
of seat materials that are designed
to meet the most demanding applications.
Each seat material has its own
performance characteristics,
enabling the user to tailor
the valve to a specific application.
A lower operating torque is
realized by the use of pressure
equalizing seats. The outside
diameter of each seat is produced
with slots that allow the media
to flow around the upstream
seat. This equalizes the pressure
on both sides of the upstream
seat, which results in the reduction
of the torque required to operate
the valve. |
