Product information

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.
