External mixture valve for CLACK WS 1

The adjustable blending valve is mounted on the filtration system’s control valve and is used to precisely mix treated and raw water, allowing fine-tuned adjustment of the final water composition. It is especially useful in applications where a minimal level of hardness or mineral content needs to be maintained — such as for drinking water or industrial processes.

Key benefits

✅ Quick installation — mounts directly onto the control valve in cold water systems with no piping modifications;
✅ Easy maintenance — periodic disassembly and cleaning of parts is sufficient;
✅ Simple and reliable design — minimal moving parts mean fewer breakdowns and longer service life;
✅ Stable water quality — enables proportional blending of raw water to maintain consistent hardness or mineral content in treated water.

Construction and operation

The valve’s unique design splits the raw water flow:

▪️One part goes through full filtration;
▪️The other bypasses the media and is blended with treated water at the outlet.

This method allows precise control over final hardness and mineralization — ideal for drinking water supply, food-grade use, or technological needs.

Compatibility

Designed for media-based filters with Clack CE 1" and CE 1.25" control valves. Fully compatible with standard softening, iron removal, and multifunctional filtration systems.

Ideal for:

▪️Maintaining optimal hardness in potable water;
▪️Adjusting taste and technical parameters of water;
▪️Protecting plumbing and appliances from overly soft (aggressive) water;
▪️Meeting custom water composition requirements.

The adjustable blending valve is a reliable, easy-to-use tool for precise water quality control in filtration systems. Simple to install, low-maintenance, and providing full control over water composition — it is ideal for residential, commercial, and industrial applications that demand balance between purity and mineral retention.
