APPLICATIONS

  • Fit­tings 
  • Val­ves 
  • Casings 
  • Covers 
  • Loa­ding arms 
  • Hydrau­lic clam­ping

CHARACTERISTICS

  • Sui­ta­ble for near­ly all fluids 
  • Dry run­ning pos­si­ble
  • Low coef­fi­ci­ent of fric­tion 
  • Very long life due to high abra­si­on resis­tan­ce
  • No chat­ter (stick-slip) at low speed 
  • Does not stick to the mating sur­face after pro­lon­ged shut­down
  • Non-sen­si­ti­ve to pres­su­re peaks 
  • Avail­ab­le for any dia­me­ter up to 700 mm

TEMPERATURE RANGE

Type 661:

From ‑54 to +200 °C (tem­pora­ri­ly up to 260 °C)

Types 641 and 681:

From ‑100 to +200 °C (tem­pora­ri­ly up to 260 °C)

Depen­dent on the U‑Cup and O‑ring mate­ri­al in each case. Spring-moun­ted ver­si­ons are pre­fera­ble for hig­her tem­pe­ra­tu­re ran­ge spe­ci­fi­ca­ti­ons.

MATERIALS

IDG U‑Cup mate­ri­al

Metal spring func­tion

The ener­gi­zer (metal spring) pres­ses the sealing lips against the sealing sur­faces by its own spring force. The pres­su­re of the flu­id for sealing also pres­ses against the lips. The­re­fo­re the total sealing force is only ever as high as requi­red to seal the pre­vai­ling pres­su­re.

The advan­ta­ges: lower fric­tio­n­al force, less wear and lon­ger life than for a seal which is always ener­gi­zed at the same level.
