AquaMatic® Control Valves K520 Noryl(TM) Series

AquaMatic® K520 Series composite control 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 the unparalleled AquaMatic® metal body valve design, along with their own design advantages. The K520 Series valve body and cap are molded with glass-filled thermoplastic. Applications include:

Water Treatment Systems Deionizers
Chemical Injection Desalinization
Evaporation Metal Recovery Systems
Process Water Systems Mining Wastes
Level Control Systems Fertilizer Spray Equipment
Electronic Industry Detergent & Bleach Handling


Key Features
  • Low Pressure Loss – Y-pattern diaphragm valve, with large seat opening and high lift disc permits higher flow rates at lower pressure loss than other comparable valves.
  • Positive Control – Separate flow and control chambers permit positive closing without springs; and only nominal cost for spring assist opening for low-pressure and selfdraining applications.
  • Cost-Effective Design – The K520 Series valve is a cost-effective solution in initial purchase price as well as in lifetime maintenance. All components can be serviced while the valve is in-line.
  • Separate Diaphragm Chambers – Separate diaphragm chambers protect the valve diaphragm from the flow stream. This allows the diaphragm to be replaced without disrupting service.
  • Long Diaphragm Life – Pre-formed, stress relieved diaphragm minimizes fatigue, maximizes valve responsiveness and diaphragm lifetime.
  • Corrosion Resistant – All internal parts in contact with media are made of composite materials. Seals are ethylene propylene for better chemical resistance.
