Body

  • Cast-in guide claws at the port bottom  for gate fixture, instead of a groove, eliminates

  • potential valve shutoff clogging while providing tight seal. These guide claws push gate

  • towards seat for tight seal in closed position.

  • Integral body design ensures easy assembly and 0 shell leakage.

  • Full port design minimizes pressure drop and maximizes flow capacity.

  • Completely enclosed structure ensures 0 leakage from valve to the surrounding, which is

  • perfect for contaminated/hazardous media for the safety of surrounding.

  • Super thin body design and compact construction contribute to easy installation.

 

GATE:

  • Beveled knife edge provides strong cutting stress and tight sealing.

  • Gate thickness can be increased to meet higher pressure.

Seat

  • Side-entry seat is replaceable, reducing the cost of maintenance.

  • L-shape seat retainer locks seat into valve body and covers seat side to prevent direct

  • flow flushing

Stem

  • Stem cover is available to ensure long service life for stem.

  • Two thrust bearings minimize torque for operation.

  • Grease nipple is available to ease bearing lubrication.
