AqMatic 1 Special Valve K521-X2SX-17973 Solenoid Assembly

AquaMatic K521-X2SX-17973 – 1 Inch Special Valve – Special Solenoid – BUNA/EP/EP

The AqMatic K521-X2SX-17973 is a 1-inch thermoplastic diaphragm valve with a special solenoid configuration, built for applications that require customized control behavior beyond standard normally open or normally closed setups.

This model is part of the K521 series, which is designed for corrosion-resistant flow control in water treatment, filtration, and chemical systems. The X2SX configuration indicates a custom valve build, including drilled and tapped bosses and a non-standard solenoid setup, allowing integration into systems with specific control requirements or legacy configurations.

The valve uses a Buna diaphragm with EP seals and discs, making it suitable for a range of water and mild chemical applications where elastomer compatibility is required. The thermoplastic body construction supports use in environments where metal valves may degrade or are not preferred.

This valve is typically deployed in automated systems using stagers and stager controls, where solenoid-driven pilot control is required. It may also be used alongside other diaphragm valves such as V42 diaphragm valves depending on system design.
