Double plate check valve wafer type
--FBE coated internally & externally
--Wafer body style fits between table E flanges
--Upper and lower PTFE thrust washers
--Resilient Buna-N or EPDM seat
--Dual Plate Valves give maximum strength With minimum opening time.
--Torsion springs assist valve closure, preventing flow reversal.
--Thrust washers reduce fiction and wear on valve plate hinges
SPLIT DISC-Cast iron body with epoxy coating and split disc design (Bronze Disc) Wafer connection ANSI 125/150 EPDM, NITRILE (Buna N) bearing. Stainless steel spring hinge pin. Lifting ring standard. Above 4".
Temp Max: 180° F(80° C) Pressure Max: 200 PSI
Two independent discs, hinged on a common shaft are held parallel against an elastomer seat by torsional spring force
Split Disc check valves are designed for simple Flange-supported installations between standard flanges in the horizontal or in the vertical flow up position. For horizontal flow applications valve must be installed with disc hinge pin in the vertical position to insure proper operation.
