AquaMatic V42 Metal Valve

Product Description

In addition to the water treatment process systems, AquaMatic Metal Diaphragm Valves are used in a wide variety of applications.

Uses of AquaMatic V42 Metal Valves

AquaMatic V42 Series Valves are constructed of cast iron and designed for air and water 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 ethylene propylene or Viton* seals.

Series 420 Valves

Standard valves are normally open. Body and cap are of cast iron. Preformed stress-relieved diaphragm of nitrile (Buna N) on polyamide, and static seals are nitrile, stainless steel and brass internal parts. Pipe sizes are 3/4- to 3-inch threaded (NPT or BSP); 3- through 6-inch flanged drilled in accordance with ASA16.1 class 125, or BSP4504
