High temperature valves

SITEC high temperature valves for fluid working temperatures ranging from -200°C to +300°C (450°C optional).
Also suitable for cryogenic applications.

Specifications
Pressure max 4.000 bar
Temperature fluid working temperature -200°C to +300°C (450°C optional)

Features and advantages

  • For extremely high temperatures or cryogenic applications, valves may be equipped with high-temperature extensions. 
    The packing is thus removed from the high- or low-temperature valve body.
  • Valve body made of AISI 316Ti stainless steel.
  • Two-piece stem with non-rotating lower stem increases service life of packing and seat.
  • Large handle for easy operation at highest pressures. Minimum required torque and no backlash problems.
  • Leakproof with gases and liquids.
  • Inert PTFE or silver packing ring.
  • Safety weep holes on tubing connections and packing.
  • Connections for inch and metric SITEC HP tubing.
  • Fluid working temperature –200°C (–300°F) to +300°C (570°F). With cooling jacket on the high-tem perature extension up to +450°C.
  • All our valves are equipped with gland nuts and collars.
  • All valves are factory tested and available short-dated.

Options

  • 6 body patterns are available.
  • For heavy duty applications the valve models with replaceable seat (type 6) are recommended.
  • Air-operated high-temperature valves.
  • Lower stem made of ceramics, tungsten carbide, etc.
  • Antivibration connectors, interchangeable with standard connectors.
  • Drive with incorporated torque limiter.
  • Cooling jacket on the extension.
