AqMatic 12 Special Valve K520-X2SX-06925 EC Solenoid Assembly

AquaMatic K520-X2SX-06925 – 1/2 Inch Special Valve – EC Solenoid – BUNA N

The AqMatic K520-X2SX-06925 is a 1/2 inch thermoplastic diaphragm valve with a special configuration and energize-to-close (EC) solenoid, designed for systems that require customized control behavior and compact valve sizing.

This model is part of the K520 series, which is engineered for corrosion-resistant flow control in water treatment, filtration, and light chemical applications. The thermoplastic body and internal components are designed for environments where metal valves may degrade or are not suitable.

The X2SX designation indicates a custom valve configuration, including drilled and tapped bosses and a non-standard control setup for integration into specialized or legacy systems. This model uses an energize-to-close (EC) solenoid, meaning the valve remains open under normal conditions and closes when electrical power is applied.

The valve is built with a Buna-N diaphragm, seals, and discs, supporting compatibility with standard water treatment applications and select process fluids. It is commonly used in automated systems controlled by stagers and stager controls, or in compact valve assemblies where space and customization are required.

PVC Union End Connector Kits

Available in ASTM (American), ISO (Metric), or JIS (Japanese) pipe standards. Designed to have PVC pipe glued directly into them. Union end connector kits consist of two each of the sockets and connecting hardware. One kit is needed per valve.

Hardware Kits for Grooved Adapters

A grooved adapter kit includes two each of the grooved adapters. It is also necessary to specify the appropriate hardware kit containing two Retaining Rings, two Retaining Nuts, and two O-rings if using Grooved adapter.
