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”).
