The IV valve

The IV valve is completely made of certified plastic material suitable for contact with food and drinking water. The material used is nylon which guarantees high rigidity and mechanical resistance comparable to aluminium. Another excellent quality of the material is its resistance to chemical agents.

Simple regeneration

The regeneration of the resins is facilitated by the sequential phase process and is carried out by manually rotating the valve knob in 4 positions:

1. Exercise
2. Pressure relief and salt loading
3. Resin rinse
4. Backwash

During regeneration, water usage is possible by the machines connected to the softener.
If there is a need to have residual hardness in the outgoing water, there is a mixer inside the valve which has the task of conveying a part of the incoming hard water directly to the outlet, so that it mixes with softened water.
