What are plug valves used for?
Plug valves are used for on/off isolation and flow diversion in pipelines, especially where fluids contain solids or debris.
What is the difference between a plug valve and a ball valve?
Both are quarter-turn valves, but plug valves use a solid plug and often perform better in dirty or abrasive service.
Do plug valves require lubrication?
Only lubricated designs require sealant injection. Non-lubricated and sleeved plug valves are designed for reduced maintenance.
Are plug valves suitable for wastewater systems?
Yes. Eccentric and sleeved plug valves are commonly used in wastewater applications due to their resistance to clogging.
Can plug valves be automated?
Yes. Many plug valves can be equipped with electric or pneumatic actuators for automated control.
