Press fit seat valves (available in HP and UHP grades).
These valves use smaller sized seats made of erther PCTFE, PFA or Polyimide that are tightly pressed to fit the valve body. In general, these valve types tend to be more economical. less comptex and more reliable. In addition, minimized seat volumes ease the problems of outgassing and seat creeping.
Soft Replaceable seat (available in HP and UHP grades)
HAM-LET standard line of valves using seats made of either PCTFE. PFA or Polyimide.
The seat-seat holder design minimizes even further the dead volume on the seat bottom. offers better sealing capabilities and extends the valve's life cycle by the possibility to easily exchange (rebuikf) worn-out seats.
All-metallic valves (available only in UHP grade)
UHP vahres with electropolished wet surlaces as a default. In these valves the diaphragm directly seals the valve's inlet. These valves don’t hâve any polymeric materials in their wetted surfaces. Therefore, such valves are ideally suited for use with high-reactivity media and the lack of polymeric seats also enables the possibility to work in elevated températures (up to 250'C in some cases).
HAM-LET standard line of valves using seats made of PCTFE.
In general, these valve types tend to be more economical. less complex and more reliable. The spécial design minimizes even further the dead volume on the seat bottom without presence of seat holder. the Soft Replaceable plug-in seat offers the possibilty to easily exchange (Factory rebuild) wom-outs seats.
