Design Features

  • Unrestricted Full Port Seatless Design provides maximum flow area and a minimum pressure drop.

  • Elimination of Metal to Metal Rotating Parts. The stationary hinge post and hinge clamp design eliminates wear of hinges, pins, valve seats, springs, and the need for routine maintenance.

  • Can be Mounted in Any Position for the most efficient piping layout. In most installations springs are not required.

  • Non Slam Quick Closure Feature. The valve plate design offers minimum travel from a full open to a full closed position and complete metal to metal valve plate structural support.

  • Unique Flexible Elastomer Seal. Continuous Elastomer Seal provides final closure around complete valve bore with strength and durability to insure prolonged cycle life, outwearing traditional metal seated valves.
