Gauge Valves - LP Series Rising Plug Gauge ValvesLP_Gauge_Valve_and_Rising_Plug_Valve_Web_Group.jpeg

Twinsburg, OH. LP Series Rising Plug valves use a unique set of features that can improve reliability and reduce the operating costs for process instrumentation applications with working pressures up to 6000 psig (413 bar) and temperatures from -65 to 600° F (-53 to 315° C).

Features include:

  • Bonnet locks that prevent the accidental disassembly of the bonnet from the valve during maintenance, operation or from system vibration.
  • Live loaded chevron packing compensates for packing wear and changes in temperature and pressure; this design maintains a leak-tight stem seal and reduces or even eliminates the need for packing adjustments.
  • Non-rotating lower stems reduce packing, seat, and stem damage that can result from the stem tip rotating onto the valve seat. 
  • Back seating stem tips make inline packing adjustments safer.

Body and bonnet material options are 316 stainless steel and alloy 400. Seat materials include Acetal, PFA and PEEK. LP Series valves are available with NPT end connection in sizes from ¼ in to ¾ inch. Valves with 2 ¼ inch extended inlets are available for use with insulated piping. Specially cleaned valves and valves for sour gas service are also available.
