I am looking for a mixing valve to automatically mix & regulate 2 water streams with varying water hardness.
Does anyone now if such valves exist?
Please send the specifics if you supply them.
very good

The system can be designed and assemble for that purpose. If you are located in the USA, there are solutions for that.

If the two lines have varying levels of hardness, the hardness level will have to be monitored to regulate the ionization level. This require inline sensors at inlets. Your feeder valve will also has its own monitor. This will feed the controller modulating the two streams for a precise feed. The monitors, valves, regulators and controllers will have to be designed and assembled to achieve your intended purpose. There will be other subsystem appended to ensure feeder line meets required level of hardness (pH/ionization level). It will be designed and assembled for that purpose.

Michael Adeyemi can you please provide more details?

Hi
Great question. I have not come across such a valve. The hardness of individual stream needs to measured first and proportionally blended their after. Control valve may be installed in one of the streams to blend required quantum of water.

The Blending Valve Panel (BVP-1) was developed for use with high-pressure humidity control systems as an effective and economical alternative to Reverse Osmosis (RO) water pre-treatment systems.
The Blending Valve Panel is designed to be used in conjunction with DI tanks for blending Deionized (DI) water with your raw supply water producing a desired water quality output in parts per million (ppm) of total dissolved solids (TDS).

Dear Maeve Hall,
There are two types of three-way valves used in the industry: Mixing Valves and Diverting Valves. In order to prevent any misunderstanding due to terminology, we will consider mixing valves to have two inlets and one outlet, and diverting valves to have one inlet and two outlets.Many people will call all three-way valves mixing valves.
Three-way valves can also be referred to as bypass valves, constant flow valves, and many other terms.
These valves are just like geyser cold & hot water mixing but for hardness control two valves are in and common outlet valve with sensor. This sensor guided the two inputs for maintaining hardness. YD and YS three-way cage-guided valves are designed for throttling or on/off service, and are available in balanced and unbalanced constructions. The YD valve is used in general converging and diverging service. The YS valve is used in general converging service.
Fisher YD and YS valves are available for a wide range of applications, including sulfide and chloride stress-cracking environments common to the oil and gas production industries.Device for water hardness monitoring with parameterizable threshold value between 0.25% and 10% soft water hardness in reference to 100% raw water hardness, DIP switches for parametrizing and LEDs for displaying of alarms and status.

Prem Baboo

You need a online hardness sensor sensor and a 3 modular 3 ways valve. Something similar to this http://www.directindustry.es/prod/fisher-regulators/product-14723-1876149.html On that valve you have 3 ways, 2 inlets and one outlet. It has a regulation system: variable actuator, positioner and flow regulator (needle, membrane...)

For the online monitoring of the hardness and the regulation of the blending/mixing valve I use a ion selective sensor system – more information to this monitoring system you´ll find here http://water-monitoring.com/produktubersicht/?lang=en or contact me directly
