Thin Type Single-plate Wafer Check Valve
This thin type of single-plate wafer check valves are swing type, that performs the same with swing check valve with much less cost. The disadvantage of this single-plate wafer check valves is, the inside diameters of the valves can only meet 60-80% of Norminal Pipe Size(NPS), which limits the flow coefficient.
Features of Thin Type Single-plate Wafer Check Valves:
One Piece Forged Steel Body
Short Face-to-face (Thin Type)
Reduced Bore, Swing Plate
Disc Spring Available
O-ring on Body Available
Applicable Standards of Thin Type Single-plate Wafer Check Valves:
a) Design&Manufacture:API 6D, API 594
b) Face to Face: API 6D, ASME B16.10, EN 558
c) Connection End: ASME B16.5, EN 1092, JIS B2220
d) Test and Inspection: API 6D, EN 12266, API 598
