Pressure reduction valves

Pressure reducing valve is a direct-acting regulating pipeline fitting designed to reduce water pressure. The valve maintains a constant water pressure in the outlet without the use of external energy sources.

As the pressure increases relative to the set value, the pressure reducing valve automatically closes until the pressure in the pipeline is equal to the set value.

Application

Pressure reducing valves are used in building water supply systems to achieve the following objectives:

• Reduction of water pressure
• Reduction of water consumption
• Exclusion of noise in water supply fittings
• Protection of equipment from high pressure

Pressure reducing valves are installed on the water inlet to the apartment or house. In water supply systems where the pressure at the inlet to the apartment exceeds 4.5 bar, installation of pressure reducing valves is mandatory according to building standards. In addition, every apartment owner has the right to install a valve at their discretion.

Advantages

• Low cost
• Simple construction
• High reliability
• Suitable for repair
• Low weight and dimensions
• No technical maintenance required
• Can be installed in any position
• No external energy sources required
• Pressure is adjusted by rotating a single adjustment screw

Disadvantages

The pressure reducing valve has a low accuracy in maintaining pressure. The pressure at the outlet of the pressure reducing valve exceeds the set value the more the degree of opening of the valve.

Replacement Options

An analog of the pressure reducing valve with greater pressure maintenance accuracy is a pressure regulator 'after itself'.
