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

  • 91B (pneu­mat­ics)
  • 62A (hydraul­ics)

O-ring elast­omer

  • NBR
  • FKM (high­er chemical/temperature resistance)
  • EPDM (steam environments)

Spring mater­i­al

  • IDG mater­i­al R43 (stain­less steel, mater­i­al No. 1.4310)

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.
