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.
