## Long description

Safety Relief Valve CALEFFI 1/2" 8 bar model 311480 is a compact brass safety valve designed to protect closed hydronic systems by discharging excess pressure when the preset limit of 8 bar is reached. Intended for use on boilers, heating circuits and hot water systems, the valve ensures system integrity by opening at the designated setpoint to prevent damage from overpressure. Its compact construction allows installation in confined spaces and integrates with standard 1/2" threaded connections.
Advantages
The CALEFFI safety relief valve is manufactured in brass for corrosion resistance and structural durability. It is factory-set to 8 bar to provide consistent and reliable pressure protection without additional adjustment. The 1/2" threaded connection offers compatibility with common heating and hot water fittings, while the compact design simplifies placement on boilers, manifolds or pipe runs. The valve operates automatically and requires minimal maintenance when installed and used within specified system parameters.
Suitable for
 Closed hydronic boiler systems
 Central heating circuits and radiators
 Hot water storage and circulation systems
 Pressure protection on heat exchangers and manifolds
Key specifications
 Material: brass body and components suitable for heating systems
 Connection size: 1/2" threaded inlet
 Set pressure: 8 bar (factory-set)
 Intended application: closed hydronic heating and hot water systems
 Operation: automatic pressure relief at setpoint
How to use
Install the valve at a suitable high-pressure point in the system where it can discharge safely to a drain or safe discharge location. Fit the 1/2" threaded connection to a compatible port, ensuring correct sealing with appropriate thread tape or sealing compound rated for heating systems. The valve is factory-set to 8 bar and operates automatically; after installation, pressurize the system gradually and check for correct operation and absence of leaks. Follow local codes and the system manufacturer’s instructions for mounting orientation and discharge piping.
Usage recommendations
Regularly inspect the valve and discharge outlet for scale, corrosion or blockage. Do not attempt to modify the factory-set pressure; if a different setpoint is required, replace the valve with a correctly rated model. Ensure discharge piping leads to an appropriate drain and that the valve remains accessible for inspection and maintenance.
