  • All models are tested in production to assure a leak-tight body joint and seat
  • Ball and poppet designs are available as standard
  • Ball type provides effective leak-tight closure with minimum flow resistance
  • Poppet models provide large fl ows with a minimum of chatter and fluctuation
  • Valves are available with various cracking pressures, from 1/3 to 25 psig (0 to 2 bar).
