With its wide operating temperature range of -320° to 1200°F (-196° to +649°C), the 4200 Series meets the demands of many critical fl uid control conditions. Operating pressure range is 0-2000 psig. Applications include high temperature liquid metals, cryogenic service, and gas analysis.



Design Features:

  • Positive plug return on all valves prevents plug sticking in severe service
  • No torque transmitted to bellows – Hex guide mates with hex broach in bonnet
  • Secondary o-ring seal in upper bonnet prevents leakage if bellows is damaged
  • Non-rising stem prevents galling or seizing of stem threads
  • Heavy-duty welded bellows provides long cycle life and assures leak tight service. Long size bellows insures full lift and utilization of full orifice area
  • All-welded design for high-temperature and high-pressure service
  • Plugs and bellows are replaceable on all gasketed types
  • Valves can be base or panel mounted – add prefix “D” to part number for panel mounted
  • Variety of materials and modifications
  • Special High Tolerance NPT Thread


Typical Applications:

  • Critical gas analysis
  • High temperature liquid metals
  • Cryogenics
