Features and Options -------------------------------------------------------------------------------------
Low Pressure Loss The AquaMatic Y-pattern diaphragm valve features a large seat opening and high lift-disc for higher flow rates at a lower pressure loss than other comparable valves.
Positive Control A separate valve flow and control chambers permits positive sealing without springs. The optional spring-assist open feature is available for low pressure and self-draining applications.
Cost Effective The AquaMatic is a cost-effective solution both in initial cost, as well as lifetime maintenance expenses.
Long Diaphragm Life Separate diaphragm chambers protects the diaphragm from the flow stream, while allowing the valve to be serviced in-line.
Durable Construction The valve is constructed of cast iron, brass, stainless steel and Nitrile elsastomer components, giving an unparalleled service life of three years or longer depending on the applications environment.

Aquamatic Valve ( V 520 Type ) п PVC ķ Ÿ

 




 

 

Features and Options ------------------------------------------------------------------------------------
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 self-draining 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**.
    Design and Application Services
    Optional Adjustable Flow Control
    Optional Position Indicators
    Optional Seal and Diaphragm Materials for Special Applications
    Optional Spring Assist
    Adaptable to a Wide Variety of Control Devices
Operating Specifications --------------------------------------------------------------------------------
  The K520 series valve is closed by introducing either hydraulic or pneumatic pressure to the upper diaphragm chamber. The control pressure must be equal to or greater than the line pressure. The valve is opened by relieving the pressure from the upper diaphragm chamber. The line pressure under the seat will then open the valve. The unique AquaMatic® Y-pattern design minimizes pressure loss in the valve.
Maximum Pressure 125 PSI (8.6 bar)
Maximum Temperature 140ºF (60ºC)
Available Options Normally Open (Standard), Normally Closed, Spring Assist Closed, Spring Assist Open, Limit Stop Flow Control, Position Indicator, Optional Seals Materials

 

          ** Valves are NOT recommended for use with any aromatic hydrocarbon based media.
