  • A short face-to-face dimension
  • Lighter weight, by 80 to 90 percent than non-conventional full-body check valves
  • Spring-loaded, double disc design has a low cracking pressure
  • The tension spring performs a lifting motion on the disc to prevent excessive wear on the "heel" area of the elastomer seat
  • The independent, dual shaft design allows interchangeability of shaft
  • The stop shaft stabilizes the disc during high flow rates
  • Field serviceable without the need for special tool
  • 6-1/16 in minimum companion flange bore
  • Cast 304 stainless steel disc, 316 stainless steel spring, 304 stainless steel stop pin/hinge pin, carbon steel plug
  • -20 to 250 deg F seat operating temperature
  • 500 deg F spring maximum operating temperature
  • 720 Cv flow coefficient
  • 200 psi at 150 deg F
  • The Keckley wafer double disc check valves are used in both vertical and horizontal application
  • For horizontal flow application the shaft should be vertically oriented and contact keckley for downward vertical flow installation
