APPLICATIONS

  • Deve­lo­ped for sealing of pivot pins 
  • Also usable on Kaplan bla­des
  • Sui­ta­ble for water and/or grea­se lub­ri­ca­ti­on

CHARACTERISTICS

  • Small base cross-sec­tions only cau­se slight com­po­nent stress
  • Avail­ab­le in any dia­me­ter up to ca. 2,800 mm 
  • Com­pen­sa­tes for eccentri­ci­ty 
  • For retro­fits the seals can be adap­ted to exis­ting instal­la­ti­on dimen­si­ons
  • Anti-twist design (types 451, 456) pre­vents unwan­ted rela­ti­ve seal moti­on and the­re­fo­re pre­ma­tu­re fail­u­re

TEMPERATURE RANGE

From ‑20 to +200 °C

Mate­ri­al descrip­ti­on and other mate­ri­als for wider app­li­ca­ti­ons FIND OUT MORE >

Pivot pins are found on shut-off devices such as sphe­ri­cal val­ves, but­ter­fly val­ves, hol­low jet val­ves and plun­ger val­ves. The­se val­ves are gene­ral­ly used for ope­ning and clo­sing and occa­sio­nal­ly to con­trol the flow rates by oscil­la­ting move­ment.

The grea­se-lub­ri­ca­ted sli­ding bea­ring is pro­tec­ted against water infil­tra­ti­on by a seal on the insi­de. The seal also pre­vents the grea­se lea­king into the insi­de to pre­vent water con­ta­mi­na­ti­on. The MANOY® sys­tem seal WP, type 418, was deve­lo­ped for this app­li­ca­ti­on.

To pre­vent leaka­ge of grea­se from grea­sed bea­rings, the uni­di­rec­tio­n­al MANOY® sys­tem seal WP, type 456, is also instal­led.
