Working pressure determined based on ASME B31.3 Process Piping, Chapter IX High Pressure Piping.
Top- or side-mounting panel holes
Glass-filled PTFE packing is standard; optional Grafoil packing is available. Design enables external adjustment without removing valve from line.
Threads are isolated from system fluid.
Inlet
Bonnet lock plate helps prevent accidental removal of bonnet.
Replaceable, nonrotating stem design: provides easy valve
maintenance helps prevent galling or Outlet damage to valve seat.
Easily replaceable seat in angle-pattern valve
