Product family

Eccentric Plug Valves

Eccentric plug valves swing a rounded plug into an offset seat, camming it firmly against the face only in the closed position — so the seat wipes rather than…

Product family

Orbit Plug Valves

Orbit plug valves lift the plug off the seat before rotating it, so the sealing faces rub only through the last fraction of travel — the rolling-and-cambering…

Four-Way Plug Valves

Four-way plug valves turn a multiple-port plug through 90° to divert flow between four pipe connections in one valve — throttling and diverting service that…
