The D05 series pressure reducing valve protects plumbing applications from excessive mains pressure . Prevents vacuum damage and reduces water consumption . Despite fluctuations in the inlet pressure, its consistency is ensured thanks to the adjustable outlet pressure. By reducing the pressure and keeping it constant, the noise generated by the water flow in the application is minimized .

Features:

• inlet pressure equalization - inlet pressure fluctuations do not affect the outlet pressure
• replaceable valve insert made of high quality synthetic material
• adjustable outlet pressure in the range 1.5 ... 6 bar with knob
• adjustable pressure scale
• the adjusting spring is not in contact with drinking water
• also available without fittings
• ACS approved
• DVGW

How the valve works

Spring-loaded pressure reducing valves operate using a system of equal forces. The force of the diaphragm acts against the force of the spring, causing the valve to open or close. If water is drawn, the outlet pressure is reduced, the diaphragm force drops and the spring can open the valve. Without water withdrawal, the outlet pressure then increases, the diaphragm force rises and the valve closes. The inlet pressure has no effect on the opening / closing of the valve.

For smooth operation, we recommend installing a filter in front of the valve.
