HTK
Utilizing the special ADAMS sealing system the HTK guarantees ultra-tightness for cryogenic and high temperature services
Due to the triple offset sealing system the disc of the block and control valve HTK moves smoothly and free of friction. It opens uniformly at all points along the specially designed body seat. When the disc is closed, the seal ring is compressed tightly into the seat without jamming or extruding. Temperature variations are reliably compensated without impairment of function.
All seal materials are reliable and designed for long life. Shafts are sealed by resilient seal rings or stuffing boxes. Choice of materials is determined according to media, pressure, and temperature conditions.
Special HTK Design
A special design of the block and control valve HTK is available for extreme high temperature services (950 °C/ 1742 °F) such as expander turbine power recovery systems for catalytic crackers in refineries. The body and disc seal elements are robust and have an additional wear resisting hard facing. Quick closing/ opening
