High temperature valves

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.
