Gate Valve
Application
Oil, Gas, Air Slurries, Heavy liquids, Steam, Noncon densing gases, Corrosive liquids
Best Suited For
Frequent on-off service Processes where “instantly” large flow is needed
Advantages
High Capacity, Tight Shutoff, Low Cost, Little resistance to flow
Limitations
Cannot be used for pressure control
Cavitate at low pressure drops
Cannot be used for throttling
RECOMMENDED USES
Fully open/xlosed, non-throttling
Infrequent operation
Minimal fluid trapping in line
JEC Gate Valves are Outside Screw, Rising Stem, Bolted Bonnet Construction, Threads are away from the line fluid and easy to lubricate.
