    Durco lined plug valves

    Considered by most to be an economical, high-quality plug valve, the Durco Lined Plug Valve provides maximum corrosion resistance while eliminating potential product contamination, below are answers to common questions we get about this valve:

    Can I use a Durco lined plug valve as a control valve?

    Perfect for on/off control using slotted and V-Port control plugs and capable of a wide-range of Cvs, the Durco lined plug valve is an ideal and accurate option. Through its complete range of Atomax Automation accessories, Flowserve offers a entire line of rack and pinion, heavy-duty, electric and linear actuators, and a full line of engineered special control circuits, solenoid valves, limit switches, positioners and actuators. Before delivering your automated package, our experts will mount and thourough test your valve prior to release.

    What is a lined plug valve?

    Plug valves are valves with cylindrical or conically tapered "plugs" which can be rotated inside the valve body to control flow through the valve. The plugs in plug valves have one or more hollowed out passageways going sideways through the plug, so that fluid can flow through the plug when the valve is open. One benefit of this design is that there is no disassembly required to restore seating. Flowserve Durco Plug Valves can be reseated with a quick and easy in-line adjustment.

    If I experience through-line leakage, can the Durco lined plug valve be reseated?

    Yes, they can be reseated, and the best part, no disassembly is required. An open wrench applied to the adjustment nut, and a few seconds is the extent of servicing necessary to reseat the valve. There are no seats to replace or piping to disconnect, which means less costly downtime, time-consuming maintenance procedures or unnecessary risk to operators. Please inquire about the Durco factory Installation Operation and Maintenance Manual for more critical information.

    The Durco lined plug valve uses PFA lining and plugs. What is PFA or Perfluoroalkoxy?

    PFA, or Perfluoroalkoxy, is a type of fluoropolymer. PFA is used as lining in piping and valves handling critical or highly corrosive processes. It has similar characteristics to Teflon which is a Dupont branded name for PTFE (polytetrafluoroethylene). What distinguishes it from the resins of PTFE is that PFA is melt processable. PFA is generally used in industry for it’s overall flexibility, and extreme resistance to chemical attack.

    How exactly is the lining affixed to the Durco line plug valve?

    The PFA valve body liner is secured to the body utilizing machined T-slots. The plug substrate has anchor holes to ensure that the PFA liner material is securely fastened to the plug.

    How can I tell if the internal sealing is leaking on my Durco Lined Plug Valve?

    This Durco lined plug valve comes with three weepholes plugged by screws on the bottom side your valve. You have the option to remove the screws. By removing these screws, one would easily detect any leakage of process fluid through the liner and take appropriate action.
