The Hex monoweld is used on upstream offshore/onshore gas and oil production and initial processing installations. 

Typically used on single or dual gauge pressure or analyzer installations to minimize the size and weight of the pipe-valve assemblies used for primary and/or secondary isolation, vent and calibration. 

Also used in downstream oil and gas refining and petrochemical production on welded, or flanged pipe processes, primary on gas applications or light end liquids.
Features
  • Non-rotating tip (NRT) conical plug stem forms consistent lapped mate with the seat ensuring bubble tight shutoff and prolonged stem and seat life
  • Robust stem and bonnet construction. Can withstand the rugged environment of offshore platforms better than any other design on the market
  • 4 rings Teflon-Chevron style packing, or multi-ring set of grafoil surrounded by braided graphite standard
  • Solid bonnet stop pin standard. Hollow spring steel pin can corrode and crack in salt water, or corrosive ambient environments
  • Combination anti-tamper with lock-out vent bonnet option
