Applications

  • Ball and poppet designs are availible as standard
  • Ball type provides effective leak-tight closure with minimum flow resistance
  • Poppet models provide large flows with a minimum of chatter and fluctuation
  • Valves are availible with various cracking pressures, from 1/3 to 25 psig (0 to 2 bar)
