** Cvdata is for 2-way straight valves.
For angle pattern, add approximately 50% to the CVvalve.
*Maximum pressure rating is based on the lowest rating of any component.
Actual working pressure may be determined by tubing pressure rating, if lower.
All dimensions for reference only and subject to change.
