Features and Benefits
Extended service life and low maintenance costs due to unique helix coil stem design, which enables friction-free opening and closing
Improved product quality, efficiency and safety with tightness performance up to ANSI FCI-70-2 Class VI
Easy in-line inspection and maintenance enabled by top-entry design
Reduced corrosion due to heavy wall thickness in excess to ASME/ANSI B16.34
Improved personnel safety from blowout-proof stem that meets international standards of API 600 and 6D
Other Features:
Combination of a quarter-turn ball valve with a linear movement of non-rotating stem
Trunnion mounted design
Reduced or full bore
Single seat (no valve body cavity)
Unidirectional or bidirectional
Metal to metal seat with stellite welding overlay (soft seat insert on request)
Outside screw and yoke for adjusting of stem packing
Blowout proof stem
Suitable for very high frequent cycling operations (switching valves)
Tight shut-off by means of application of external mechanical force and not dependent on differential pressure
Proper selection of materials to avoid galling and high friction
Protected lower trunnion against solid particles intrusion
Clearance control to consider high/low temperature shrinkages
Self-cleaning closure member
