AquaMatic® series K520 composite valves are designed to handle deionized water as well as acids, caustic harsh chemicals or gases that would rapidly corrode metal valves.
The valves are constructed of corrosion-resistant materials, but still have all of the advantages of unparalleled AquaMatic® metal body valve design, along with their own design advantages. The K520 series valve body and cap are molded with glass-filled Noryl* thermoplastic.
Y-pattern diaphragm valve, with large seat opening and high lift disc Separate flow and control chambers Separate diaphragm chambers All components can be serviced while the valve is in-line Pre-formed, stress-relieved diaphragm All internal parts in contact with media are made of composite, corrosion resistant materials* Seals material: ethylene propylene** Valve is compatible for 3/8- to 3-inch pipe sizes Adaptable to a wide variety of control devices
* Normally closed valve configurations are NOT recommended when used with corrosive fluids. ** Valves are NOT recommended for use with any aromatic, hydrocarbon-based media.
