Pressure regulator CALEFFI 533241 for water 1/2" 16 bar with pressure gauge

CALEFFI 533241 pressure regulator for water 1/2" 16 bar with pressure gauge is a compact pressure-reducing valve designed to stabilize downstream domestic and light commercial water systems. The unit features a 1/2" connection and an integrated pressure gauge that allows quick visual verification of inlet or reduced pressure. Built to reduce supply pressure to a safe, consistent level, this regulator protects plumbing fixtures, appliances and sanitary fittings from excessive pressure and reduces noise and wear caused by pressure surges.

Advantages

The CALEFFI pressure regulator provides reliable pressure reduction with precise control and an integrated pressure gauge for on-site monitoring. Its construction is intended for straightforward installation on 1/2" water lines and offers corrosion-resistant materials suitable for potable water. By maintaining a stable downstream pressure, it minimizes stress on valves, taps and appliances, lowers the risk of leaks, and helps to extend the service life of system components.

Suitable for

• Residential cold and hot water supply systems
• Small commercial premises and light-duty installations
• Protection of sanitary fittings, washing machines and water heaters
• Installations where inlet pressure exceeds desired downstream levels

Key specifications

• Connection size: 1/2" (female/male thread as per product design)
• Maximum operating pressure: 16 bar
• Integrated pressure gauge for local pressure reading
• Designed for potable water use
• Compact body suitable for confined installation spaces

How to use

Install the regulator in the cold or mixed water supply line following the flow direction marked on the body. Ensure system isolation and depressurization before installation. Fit appropriate thread seals and secure connections to avoid leaks. After installation, adjust the downstream pressure according to the required setting by following the manufacturer's adjustment procedure and confirm the value on the integrated gauge. Check for leaks and verify stable pressure under normal operating conditions.

Usage recommendations

Periodically inspect the pressure gauge and fittings for integrity and proper function. If sediment or hard water is present, consider pre-filtration to reduce wear and maintain regulator accuracy. For any maintenance or adjustment beyond visual checks and minor re-setting, consult qualified plumbing personnel and follow local regulations and standards.
