GeneralThe VFA butterfly valve is an economical solution for medium to low duty butterfly valve applications. The valve is made
of durable PVC and its light weight is a good fit for systems already incorporating plastic pipe and fittings. The disc seal
is separate from the flange seal reducing torque requirements. Primarily aimed at water applications, the valve is available
in sizes 2 ½” to 8” and can handle 150PSI (90 PSI for 8”).
