Reliability at high temperatures and large nominal widths
The strength of HTK valves is their absolute tightness at temperatures up to 950 °C. The triple eccentricity combined with the special metallic sealing system in the valve ensures easy opening and closing, even at extreme temperatures.
Our state-of-the-art welding technology makes it possible to work with large nominal widths and enables us a great deal of exibility with which we manufacture special lengths and custom-made valves in accordance with the requirements of our custo- mers. Whether a heating jacket, single- or double-row steam injection, or valves that open and close at extremely high speeds: we provide customised solu- tions for the HTK for a wide variety of purposes. The compact design of the valve, even for large nominal widths, makes the HTK the valve of choice for both underground and overhead lines.
The HTK is available both as a standard model and in a variety of customised designs. The custom-made models include:
• The HTK for ethylene plants
The TLV transferline valve and the DV decoking valve
• The HTK block & bleed
Two seals are placed one behind the other in the seal seat. A chamber between the seals can be used to suction off residual leakages or for barrier media.
• HTK for FCC plants
Valves with expander inlet and bypass for coping with extremely high temperatures and abrasive media.
