- AQMatic is the official brand name today. Aquamatic is the older/original spelling that people used for decades.
- AQ Matic manufactures diaphragm and piston control valves in cast iron, bronze, stainless steel, and corrosion-resistant composite materials. They offer both metal and plastic valve bodies, with diaphragm options in Buna-N, EPDM, and Viton. Valve types include air-operated, solenoid-actuated, diaphragm, piston, and lightweight composite models.
- AquaMatic valves are used anywhere you need reliable, low-maintenance control of water or process fluids. Typical applications include water softening and filtration systems, industrial water treatment, wastewater systems, reverse osmosis pretreatment, deionization systems, and chemical or corrosive fluid handling (when using composite or stainless models). They’re also common in OEM skid packages, municipal water systems, cooling towers, and general industrial process control where simple, durable diaphragm valves are preferred.
- A Normally Open (NO) valve stays open when no power or air signal is applied. It only closes when it receives a control signal. A Normally Closed (NC) valve stays closed by default and only opens when it’s energized or actuated. Which one you need depends on what you want the system to do in a loss-of-power or loss-of-air situation: - Choose NC if the safe/default condition is stopping flow. - Choose NO if the safe/default condition is allowing flow. In water treatment, NC is more common because you typically want the system to shut off automatically if something fails. NO valves are used when maintaining flow is critical or when a system needs to depressurize or drain by default.
