Superior Valve Products

Introduction:

Omni Model CX (WKM Model "M" interchangeable) cast-body expanding gate valves are designed for oil and natural gas
wellhead or other critical service applications with operating pressures from 2,000
to 5,000 psi. 

Features:
Operating Temperatures
Model CX valves are available with API 6A Temperature ratings of -50 F through
+650F. Valves for API Temperature ratings of X and Y are pressure de-rated as
required per Annex G of API 6A 20th Edition.

Expanding Gate
The expanding gate is field-replaceable and provides a tight mechanical seal that
does not rely on line pressure. This ensures seal integrity at both high and low
pressures.

Seat Designs
The standard gate to seat and seat to body sealing interface is a slip-fit design,
assisted by inserts in the face and rear of each seat. Metal-to-metal gate to seat
and pressed-fit seat to body sealing is used for high-temp valves and is otherwise
available upon request.

Packing Design
Chevron style stem packing is replaceable and can be re-energized by injection
between the packing stacks. This ensures efficient sealing for the life of the
valve. Graphite packing is used for high-temperature applications.

Body Lubricant
All Model CX valves are shipped with body filler grease appropriate for the
material class and temperature rating of the valve to ensure smooth operation of
the valve under pressure and to prevent corrosion during storage prior to
deployment.

Grease Fittings
The valve body may be lubricated through the grease fittings provided in the valve
body. All fittings meet the requirements of NACE MR0175.

Exposed Bolting
All exposed bolting meets the requirements of NACE MR0175.  Full Through Conduit
Bore The full through conduit bore provides for smooth flow with minimal turbulence. It also provides an unobstructed passage for well intervention tools.

NOTE: All Model CX valves are drift tested in accordance with API 6A 20th Edition
requirements.
