  • Block & Bleed valves LN Series Series Cover

LN Series block and bleed valves are used in demanding oil & gas exploration, refining, high pressure instrumentation, test stands, steam systems and many other applications having pressures up to 6000 psig (413 bar), temperatures from -100 to 1200°F (-73 to 648°C), high vibration, and frequent cycling.  There are two designs:

  • LNBB Series are block and bleed valves featuring LN Series bonnets for both isolation and bleed functions to allow safe maintenance of instruments in systems with media that must be contained.
  • LNBP Series are block and bleed valves featuring an LN Series isolation valve and an integral bleed port to allow maintenance of instruments having non-hazardous media.

Our website contains the most popular LN Series needle valve configurations - more options and accessories are available.  For more information, contact SSP Customer Service.
