Perry's Chemical Engineers' Handbook, Eighth Edition > PROCESS PLANT PIPING
Vertical lift check valves are for installation in vertical lines with flow normally upward. Globe (or piston ) valves with a 90° bonnet (Fig. 10-161) are for installation in horizontal lines, although inclined bonnet versions (approximately 45°) with spring assist may be used in vertical lines with normally upward flow.

Recommendations for the treatment of aging in standard technical specifications
Consequently, most CVs have no capability to be actuated except by changing flow through the valve . The several types of CVs used, depending on the application and the system configuration, include swing- check , horizontal - lift , vertical-lift, piston -lift, ball, stop-check, tilting-disc, and duo-check.
