LN Series Gauge Valve Options and Accessories
In addition to the product offered on our website, other options and and accessories are available.  These include:

• Pipe Socket Weld End Connections
• Speciall Clean in accordance with ASTM 93G Level C
• Sour Gas Service (NACE MR01-75/ ISO 15156)
• Panel Mount Nut

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.
