Model '125TDFI'

Available in sizes 2" to 12" with ANSI 125# FF flanged ends for maximum operating pressures as follows:
PMO: (Maximum Operating Pressure)
200 psi @ 150 deg. F.

Materials of Construction:
  • Body: Cast Iron
  • Disc: Bronze
  • Stem: Stainless Steel
  • Seat Ring: Nickel Plated Ductile Iron
  • Seat Seal: EPDM O-Ring (Viton Optional)
  • Disc Seat: EPDM O-Ring (Viton Optional)
Features:
  • Acts as three valves in one. On a pump discharge, the triple duty valve eliminates the need for a separate balancing valve, shut-off valve and check valve.
  • These valves are designed for vertical upward or horizontal flow patterns.
