Fully Lined wafer swing check valves are ideal for use in totally
lined piping systems or to replace costly high alloy valves in
corrosion applications. The valve can be mounted horizontally
or vertically with upward flow.

Tufline wafer swing check valves are of two piece construction
with only one moving part. Integral hinge pins fit into the valve
body recess. There are no springs or pins to corrode or wear.
