Hayward Flow Control Systems

general description

a better butterfly valve: hayward 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 holes 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 ensures that the valve operator will function reliably, regardless of the operator used; lever handle, gear operator or actuator.
extra features, no extra cost: hayward 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.

general description

designed for performance and flexibility: larger size butterfly valves from hayward are specially designed to take into account applications parameters encountered in larger size piping systems. The rugged, one piece all plastic body stands up to high flow rates and elevated stress conditions. The valve features a full face liner that eliminates the need for expensive flange gaskets. The valve itself is fully lined and the standard type 316 stainless steel stem is completely isolated from the process media. A unique "sphered" disc makes it easy to seal the valve bubble tight with a minimum of operating torque. The valve's fabricated design makes for exceptional application flexibility. This type of design makes it easy and cost effective to modify the valve to conform to the requirements of special, demanding applications. For example, the need for expensive and clumsy flange adapters can be eliminated by providing a 14" size valve with a 16" bolt circle, an easy modification for these types of valves.
