Product information

Description

Safety Valve CALEFFI 3/4" 8 bar model 311580 is a compact brass pressure relief valve designed to protect pressurised systems by releasing excess pressure when the setpoint is exceeded. The valve is suitable for heating, hot water and general plumbing installations where reliable overpressure protection is required. Its robust construction and straightforward operation provide consistent safety performance and accessible maintenance.

Advantages

The CALEFFI 3/4" 8 bar safety valve features a durable brass body that resists corrosion and maintains dimensional stability under typical system conditions.

Key specifications

Connection size: 3/4"
Relief pressure: 8 bar
Material: brass body
Function: pressure relief / safety valve
Application: heating, hot water, plumbing systems

How to use

Install the safety valve in a vertical orientation on the system pressure line or at the designated safety port, following local codes and the system manufacturer’s instructions. Ensure the outlet is directed to a safe discharge area and that thread sealing is applied correctly to the connection. Verify that the valve’s relief rating matches the system maximum allowable working pressure before commissioning. After installation, perform a pressure test to confirm correct operation and check for leaks around the connection.

Usage recommendations

Periodically inspect the valve and discharge line for blockage, corrosion or mineral buildup. Replace the valve if it shows signs of leakage, corrosion, or if it fails to open at the designated pressure. Ensure maintenance and replacement are carried out by qualified personnel and comply with applicable regulations and safety standards.
