CA CHOKE VALVE SERIES

TECHNICAL DATA SHEET FOR MAXIMUM TRIM SIZE OF 1.18”

The ‘CA’ product family of production choke valves utilize a 0.75” to 1.18” orifice and offer the ability to manually or remotely control well production flow at the wellhead and or flowline with a more conventional type choke body. The cage & plug flow trim is pressure balanced to minimize the stem loads and provide low operating torques. Standard end connections range in size from 1” to 4”.

* “C” and “D” shown with 3” x 2” reduced orifice trim
1. Using our 24vDC actuator shown, “E” is 11.97”; Pneumatic & Hydraulic units are also available as well as other
Electric units
2. For sizes or dimensions not shown, for ANSI flanges or hub connections, contact sales or engineering
3. In addition to “C”, provide clearance for bonnet and trim removal as follows (worse case – with trim in fully
closed position): 1.0” (25.4) Nominal, add 7.81” (198.37) for needle trim; add 6.75” (171.45) for cage trim
4. (xxx.xx) dimensions shown in parenthesis are in millimeters (mm)
5. Orifices in X/64ths are openings with the equivalent area of a circle with the diameter of X/64ths of an inch;
64/64ths = 1.00”
6. API 5,000 psig is equal to 34.473 MPa; 10,000 psig = 68.946 MPa; 15,000 psig = 103.420 MPa; 20,000 psig =
137.893 MPa.
7. Dimensions shown above are subject to change without notice. Other dimensions are available, please consult
