Hansen Check Valve Hi-Flo

Hansen HiFlo check valve is used in-line to stop fluids reverse-flowing
in the pipe. The unique Hansen design reduces flow restriction to the
minimum. The screw cap allows for easy valve-access for service or
replacement of diaphragm and spring. (Replacement diaphragm and spring
sets are common to both check valves and foot valves of same dimension.)
