Gauge/Block Valves - HG48 Series

HG48 Series Gauge/Block Valves


The HG48 gauge/block valve provides three outlet connections to facilitate the mounting of gauges and other static pressure instruments in a variety of positions. The design creates a compact installation with fewer leak points as compared to conventional mounting requirements due to the reduced number of threaded connections. The HG48 can be supplied with an in integral hard seat which matches the body material, or with a choice of soft seal materials including PPS, Kel-F, TFE, or PEEK.


  • High Temperature, Full Ported - Use on viscous services up to 850°F. Universal 1/2" outlets allow rodding tool positioning without the removal of tubing or instrument.
  • Easy Maintenance for Long Service Life - Easy to remove non-rotating stem tip allows for easier maintenance than found with conventional valve designs.
  • reduce Installation Time - Threads directly into the orifice flange for quick, compact and simple installation.
  • Reduce Potential Leakage - Reduces the number of threaded connections in half resulting in fewer potential leak points as compared to conventional root valve assemblies.
