AquaMatic K52 Composite Valve

Product Description

AquaMatic K52 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. The K52 Series Valve body and cap are molded with glass-filled thermoplastic.

AquaMatic K52 Composite Valves

AquaMatic K52 Series Valves provide the time proven advantages of the y-pattern design for pipe sizes from 1/2- to 3-inches. The body and cap are molded in strong, glass-filled thermoplastic and the diaphragm is made of durable Buna N or Viton* materials. Various pipe end connections are available for your system design. Other AquaMatic Composite Valve options include spring-assist open, spring-assist close, flow control limit stop, poppet position indicator, Viton* seals, butyl seals, normally closed, and fail-safe spring closed products.


Operating Specifications:

  • Maximum Pressure 125 psi (8.6 bar)
  • Maximum Temperature 140°F (60°C)
  • Operation The K52 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.
  • Large Seat opening and high lift-disc for higher flow rates at a lower pressure loss
  • 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 solution both in initial cost, as well as lifetime maintenance expenses
  • Separate diaphragm chambers protects the diaphragm from the flow stream, while allowing the valve to be serviced in-line
  • Pre-formed, stress relieved diaphragm minimizes fatigue, maximizes valve responsiveness and diaphragm lifetime
  • All internal parts in contact with media are made of composite materials
  • Can be actuated with either air or water as control fluid
  • Designed for water treatment applications including those requiring acids, caustic and harsh chemicals that would rapidly corrode medtal valves
  • Seal and diaphragm materials available
  • Spring assist (open or closed)
  • Normally open or closed
  • Position indicator
  • K55 isolated bonnet valve
