COMMERCIAL CONTROL VALVES ® AquaMatic Diaphragm Valves V42 Series AquaMatic Series Diaphragm Valves are equipped with a 3-way solenoid for direct or remote control. The solenoid can be actuated by a timer, pressure or temperature sensor or liquid-level switch. These valves are ideal for automated process systems. In addition to the water treatment process systems, the valves are used in wide variety of applications. Typical Applications • Concrete Additive • Agricultural Irrigation • Turf Irrigation • Pump Controls • Fuel Handling • Cooling Towers • Level Control Systems • Car Wash Systems • Process Water Systems • Laundry Equipment • Conveyor Systems • Air Control Systems • Dust Suppression ® COMMERCIAL AquaMatic CONTROL VALVES Diaphragm Valves V42 Series Features and Benefits • Low Pressure Loss – • Durable – The AquaMatic The unique AquaMatic V42 Valve features cast iron, Diaphragm Valve’s y-pattern brass, stainless steel, and design, with large seat nitrile elastomer components. opening and high lift disc, The valve features an average permits higher flow rates life of 3 years or longer at lower pressure loss than depending upon cycling rate other comparable valves. and environment. • Cost-Effective Design – • Pipe Sizes – 3/4- to 3-inch The AquaMatic V42 Valve is threaded (NPT or BSP); a cost-effective solution in 3- to 4-inch flanged drilled initial purchase price as well in accordance with ASA16.1 as in lifetime maintenance. class 125, or BSP4504. All components can be • Adaptable to a Wide serviced while the valve is Variety of Control Devices in-line. • Design/Application Options Engineering Service – Spring-assist closed – Spring-assist open – Limit stop – Adjustable flow rate control – Seal and diaphragm materials for special applications Operating Specifications Working Pressure 125 psi (8.6 bar) Maximum Temperature 150°F (65°C) Operation The AquaMatic Diaphragm Valve is a normally open valve, controlled by a 3-way universal solenoid, supplied as a complete assembly. Three basic models are available: energized to open, energized to close and independent control pressure. Principle of operation for the three models are: Energized to Open Line pressure is directed through the solenoid to the upper diaphragm chamber, closing the valve. Activating the solenoid vents the upper diaphragm chamber, allowing the valve to open. Energized to Close Line pressure is directed through the solenoid to upper diaphragm chamber, closing the valve. Deactivating the solenoid vents the upper diaphragm chamber, allowing the valve to open. Independent Control Pressure An independent source of pressure is used through the solenoid to control the diaphragm valve.
