Poolmaster Series butterfly valves

Poolmaster Series butterfly valves feature a polyvinyl chloride (PVC) body and a disc with an ethylene propylene diene monomer (EPDM) liner. The valves are not vulnerable to electrolytic and galvanic corrosion, and they contain no byproducts that can contaminate water and process fluids. Unlike other plastic butterfly valves, these are constructed from a one-piece body that incorporates fully supported flanged bolt holes to prevent stressing of the mating pipe flanges. A blowout-proof Type 316 stainless steel shaft and a full body liner ensure positive sealing of the liner to the valve body. A solid integral ISO 5211 mounting pad enables smooth operation with a lever handle, gear or actuator. Options include gear operators, electric or pneumatic actuators, actuator mounts, and stem extensions. The valves are available in 2.0–8.0 in. sizes.
