Pressure-Balanced Plug Valve

Industrial valves and fittings dispatch fast — wear parts and complete machines quoted on request.

Plug Valves

Plug valves for on-off isolation where a gate valve would pack solids: a quarter turn takes the tapered plug from open to shut, and the seat can be re-greased or the gland re-tightened in line. Standard, soft-seated, lifting metal-seal and pressure-balanced builds, NPS 1/2 to 48 at Class 150 to 2500, to API 599 / API 6D. Images are representative renderings of each series; finish, accessories and nameplate follow the confirmed drawing.

Pressure-balanced plug valve for gas and product lines. Line pressure is routed to the bottom of the plug so it balances the load on the seat, which keeps operating torque low and lets one operator work a large valve. Grease injection points on the body and cover allow the seat to be re-sealed in service. Body in carbon steel, alloy steel, stainless steel, duplex or nickel-base alloy; flanged, RTJ or butt weld ends.
