## Long description

CALEFFI pressure reducing valve 533051 in chrome finish is designed to lower and stabilize incoming water supply pressure for residential and light commercial plumbing systems. With a 3/4" connection size and a maximum rating of 16 bar, this pressure reducing valve provides a steady downstream pressure to protect fixtures, appliances and piping from overpressure and to improve the performance and life of downstream fittings.
Advantages
The valve features a chrome-plated body that resists corrosion and is simple to clean. Its compact design allows installation in confined spaces on the mains feed. The valve provides reliable pressure regulation, reducing pressure fluctuations and helping to prevent leaks and damage caused by excessive supply pressure. Built for compatibility with common plumbing systems, it delivers consistent downstream pressure with minimal maintenance.
Suitable for
Domestic water supply pressure reduction on the main inlet
Small commercial and light industrial plumbing installations
Protection of water-using appliances such as boilers, mixers and washing machines
Pressure stabilization for sanitary fixtures and irrigation control points
Key specifications
Connection size: 3/4" (female thread)
Maximum inlet pressure rating: 16 bar
Finish: chrome-plated
Function: pressure reduction and stabilization
Typical application: mains feed installation upstream of fixtures and appliances
How to use
Install the valve on the mains cold-water inlet in accordance with local plumbing codes and the system layout. Ensure flow direction matches the arrow indicated on the valve body. Isolate the mains supply and drain the line before fitting to avoid water spillage. After installation, gradually open the inlet supply and adjust the downstream pressure according to system requirements using the valve's adjustment mechanism, then secure the adjustment. Verify downstream pressure with a suitable gauge and check for leaks at connections.
Usage recommendations
Use a certified pressure gauge to set the required downstream pressure and routinely inspect the valve and connections for signs of wear or leakage. Consider installing a filter or strainer upstream to prevent debris from affecting valve operation. Follow local regulations for installation and maintenance intervals to ensure reliable performance.
