Clack (V4099)-WS1 Proportional Valve
Clack V4099-WS1 Proportional Mixing Valve
External in-line blending valve for precise hardness or chlorine adjustment on Clack 1" and 1.25" control systems
Controlled blending for real-world water chemistry
Proportional Control
Adjustable mixing valve allows you to dial in the exact ratio of treated to raw water, whether you're reintroducing hardness for taste or maintaining residual chlorine for distribution systems.
Universal Clack Fit
Adapts to any Clack 1" or 1.25" control valve, including 1191 and 1190FP in/out heads and inline bypass configurations without modification.
Dual Application
Use on softeners to blend back a desired hardness level for corrosion control and taste, or on carbon filters to maintain low-level chlorine residual for downstream protection.
External Installation
In-line design allows for easy installation and adjustment without disassembling the control valve or interrupting system operation during calibration.
Works with Clack commercial control systems
The Clack V4099-WS1 proportional mixing valve is designed for use with all Clack 1" and 1.25" control valves, including the 1191 and 1190FP models with in/out head configurations or inline bypass assemblies. Compatible with both water softening and carbon filtration applications where blending of raw water is required.
Precision Blending
Adjustable ratio control for exact water chemistry targets
Fast Install
External in-line design mounts without valve disassembly
Field Adjustable
Tune blending ratio on-site to match application needs
Clack Quality
Built to the same commercial standards as Clack control valves
