VAV & V42 Series
The AquaMatic VAV and V42 Series valves are constructed of cast iron and are designed for air (VAV) and water (V42) applications. A separate control chamber protects the diaphragm from line fluid and extends cycle life. Reinforced diaphragm of Buna N or Viton materials are pre-formed and stress relieved to maximize responsiveness and product life. The valve is highly serviceable even while in line. A variety of options are available such as spring-assist open, spring-assist closed, flow control limit stop, normally closed, poppet position indicator, and high temperature EP or Viton seals.
V82
Series – High Pressure
The AquaMatic V82 Series valves are constructed of brass and are identical in operation to
the V42 Series. Body and cap are brass, and components are designed to withstand up to 250
psi (17 Bar).
PLASTIC
K52 & K53 Series
The AquaMatic K53 Series valve is designed for controlling the flow of most fluids
including deionized water, salt solutions, and corrosive fluids such as acids and caustics
that would rapidly corrode metal valves. These valves, constructed of corrosion resistant
materials have all advantages of the AquaMatic® K520 series composite body valves. In
addition, the K530 series valves boast a number of additional added features. The rugged
construction employs strong corrosion-resistant glass-filled Noryl components. The
“Y” pattern design permits high flow with low pressure drop. Separate flow and
control chambers provide positive closing without springs. Dual “O” ring design
on the shaft prevents leakage between the flow and control chambers and the cap is easily
removed for maintenance purposes. True union end design with female socket weld
connections provide easy installation and servicing.
