Resun plug valves are used in countless industrial and general utility applications. Round port, full-opening, through-conduit RESUN plug valves are ideal for slurries or other services where only minimum flow restrictions can be tolerated or where any pressure drop is unacceptable. Resun plug valves require minimal maintenance. Only a small initial charge of sealant is required with occasional recharging for easy operation. The basic construction of Resun plug valves simplifies any service or parts replacement which might become necessary.
