The D03 series brass reducing valve protects boilers against excessive network pressure. It prevents damage from vacuum and reduces water consumption. Despite fluctuations in input pressure, the adjustability of the output pressure ensures its consistency. By reducing pressure and maintaining its constant level, noise is minimized due to water flow in the application.

Features:

• input pressure equalization - fluctuations in input pressure do not affect output pressure
• adjustable output pressure in the range of 1.5...6 bar with an adjustment screw
• adjustment spring is not in contact with drinking water
• compact design
• ACS approval

How the valve works

Spring-loaded reducing valves operate using a force balance system. The force of the diaphragm acts against the force of the spring, causing the valve to open or close. When water is drawn, the output pressure decreases, the diaphragm force drops, and the spring can open the valve. Without water draw, the output pressure increases, the diaphragm force rises, and the valve closes. The input pressure has no effect on the opening/closing of the valve.

For smooth operation, we recommend installing a filter before the valve.
