Plastic Butterfly Valves from Hayward
A Better Butterfly Valve: Hayward Plastic Butterfly Valves up to 12" 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 flange bolt holes (the valve has the same number of bolt holds as the matching 150# ANSI flange). This prevents stressing of the mating pipe flanges. The heavy duty construction of the valve stands up to the most demanding applications. The rock solid integral mounting pad insures that the valve operator will function reliably, whatever operator is used, lever handle, gear box, or actuator.
Extra Features, No Extra Cost: Hayward Plastic Butterfly Valves feature a blowout proof 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. And the lever handle has a built in lockout feature.
Better Sealing: Other plastic butterfly valves have only a thin o-ring on the disc 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 Plastic Butterfly Valves can be easily fitted into a metal piping system. All valve sizes meet 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 through them.
