Hayward 1-1/2˝ through 12˝ all-Plastic Butterfly Valves are rated at a full 150 PSI. Unlike other plastic butterfly valves, Hayward valves are constructed from a one piece body that incorporates fully supported flanged bolt holes to prevent stressing of the mating pipe flanges. Their heavy duty construction stands up to the most demanding applications. The rock solid integral mounting pad ensures that the valve operator will function reliably – whichever operator is used, lever handle, gear box or actuator.
Extra Features, No Extra Cost
Hayward Butterfly Valves feature a blowoutproof stainless steel stem and a unique, full body liner that has a V-notch retention design. This assures positive sealing of the liner to the valve body. An integrally molded face seal provides positive sealing against the mating flange without the need for additional gaskets. The lever handle has a built in lockout feature and every Hayward valve is ready for actuation.
Better Sealing
Other plastic butterfly valves have only a thin o-ring on the disk to seal the valve, but Hayward valves feature a full body liner seal. This means that the process media never contacts the valve body. And you can count on the full liner seal to perform reliably, year after year.
Easy Retrofit
Hayward Butterfly Valves can be easily fitted into a metal piping system. All valve sizes meet industry face-to-face standards – allowing simple retrofit.
No Metal, No Corrosion
These valves have no metal in contact with the process media. They cannot corrode or rust–nor will they contaminate sensitive fluids flowing thro
