INSTRUMENTTION -Valves & Manifolds
 
VB16 series Barstock Needle Valves
 
    Inline Pattern Angle pattern  
  • Up to 6000psig (413 bar)
  • Up to 232? (450?)
  • SS316 and Alloys
  • Vee Tip standard
  • Compact design
  • DK-LOK OD1/4 - 1/2 inch
  • Electra OD1/4 - 1/2 inch
 
Features
  • Two-piece chevron-style PTFE stem packing design with compensating disc springs
  • reduces packing friction wear
  • reduces valve operating torque
  • reduces load to seal
  • Packing is supported by lower and upper Glands as well as compensating disc springs reduces need for packing adjustment

Flow Data
Cv are measured at the valve. Therefore restrictions in end connections may reduce flow.
Factory Test
Every valve is tested with the nitrogen @68 bar (1000 psig) for leakage at the seat to a maximum allowance leak rate of 0.1 scc/min. The stem packing is tested for no detectable leakage.
