One of the most important ingredients to make you horticultural plants grow well is water with the right quality. At the same time it is very important to be efficient with the use of water and fertilizers. That’s why many companies reuse drain water.

After disinfecting the drain water, one has to mix it in the right balance with clean water. In order to reach this balance, they use mixing valves also know as twin valves. Based on the desired EC in the irrigation water, the mixing valves automatically mix the recycled drain and clean water by opening one and closing the other a bit or vice-versa. This is done by monitoring the EC of the mixed water with an EC sensor.
The mixing valves can be delivered with pvc butterfly valves in the sizes from 50 to 200 mm. For the sizes 50 to 75 JC servomotors are used, from 90 up to 200 mm the OM motors are used. Upon request we can also mount other motors on the mixing valves. Also we can deliver the valves in stainless steel, composeal or cast iron, besides we have the option to build the motors upon shaft extensions in case the piping is under ground.
