## Summary description

CALEFFI pressure regulator with replaceable cartridge and integrated pressure gauge, 1" connection (model 535161). Designed to control and stabilize water pressure in plumbing and heating installations. The replaceable cartridge simplifies maintenance and the built-in manometer allows on-site pressure monitoring. Suitable for residential and light commercial systems.

## Long description

CALEFFI pressure regulator with replaceable cartridge and integrated pressure gauge, 1" connection (model 535161) is a compact pressure-reducing valve designed to control and stabilize incoming water pressure in domestic and light commercial plumbing and heating systems. The unit combines a pressure regulator body with a replaceable internal cartridge for straightforward maintenance, and a built-in manometer for direct pressure reading during installation and service.
Advantages
The replaceable cartridge design reduces downtime and service costs by allowing internal parts to be swapped without replacing the entire valve body. The integrated pressure gauge provides immediate visual feedback for accurate adjustment and verification of downstream pressure. Constructed for compatibility with standard 1" piping, the regulator supports reliable pressure control and helps protect downstream fixtures and appliances from pressure surges and fluctuations.
Suitable for
 Residential water supply pressure reduction
 Small commercial and light industrial plumbing systems
 Protection of boilers, boilers' circuits and heating components from high inlet pressure
 Prevention of damage to domestic appliances, taps and valves
Key specifications
 Connection size: 1" (inlet/outlet)
 Replaceable internal cartridge for maintenance
 Integrated pressure gauge for downstream pressure monitoring
 Suitable for potable water and heating applications (check local codes for specifics)
 Mechanical pressure reduction mechanism for stable downstream pressure
How to use
Install the regulator in the main feed line following the system flow direction marked on the body and observe standard installation practices: isolate the water supply before fitting, ensure proper thread sealing and support the piping to avoid stress on the valve. Use the integrated manometer to adjust the outlet pressure to the required setpoint by turning the adjustment element until the gauge shows the desired value. Once set, verify downstream fixtures and retest after system pressurization to ensure stable operation.
Usage recommendations
Regularly inspect the pressure gauge and, if pressure drift or leakage is observed, replace the cartridge to restore correct performance. For installations supplying potable water, follow local regulations and consider installing a filter or strainer upstream to reduce the risk of debris damaging the cartridge. Periodic checks during annual maintenance will help maintain consistent pressure control and prolong the service life of downstream equipment.
