## Long description

Safety valve Afriso AF4 is a pressure relief device engineered for electric water heaters, set to open at 6.7 bar to prevent unsafe overpressure. The valve has threaded connections G1/2 and Rp1/2 (S)A to match common heater outlet fittings and is intended to protect both the appliance and the connected plumbing by releasing excess pressure. Designed for domestic and commercial water heating systems, this component supports reliable and safe operation of hot water installations.
Advantages
The Afriso AF4 safety valve offers precise pressure relief at a defined setpoint of 6.7 bar, reducing the risk of equipment damage and plumbing leaks caused by overpressure. Its threaded G1/2 and Rp1/2 (S)A connections provide straightforward mechanical compatibility with standard heater outlets, enabling secure and leak-minimised installation. The valve’s compact design facilitates fitting in confined spaces common around electric water heaters and allows predictable discharge behaviour to protect both the heater and downstream piping.
Suitable for
 Electric domestic water heaters
 Small commercial hot water systems
 Replacement of malfunctioning or aged pressure relief valves
 Plumbing systems requiring a 6.7 bar safety relief point
Key specifications
 Set pressure: 6.7 bar
 Inlet/outlet connections: G1/2 and Rp1/2 (S)A threaded
 Application: pressure relief for electric water heaters

How to use
Install the Afriso AF4 safety valve onto the designated outlet of the electric water heater using the matching G1/2 or Rp1/2 (S)A threaded connection, ensuring thread sealing appropriate for hot-water applications. Verify the valve orientation and secure mounting according to the heater manufacturer’s instructions. After installation, pressurise the system and check for leaks; perform a functional test by gradually raising system pressure to confirm valve operation at the specified 6.7 bar setpoint. Follow local plumbing codes and safety procedures during installation and testing.
Usage recommendations
Inspect the valve periodically for corrosion, mineral buildup or signs of leakage and replace if operation becomes unreliable. Use compatible sealing materials rated for hot water and ensure discharge piping is directed to a safe drainage location. If the system requires a different relief pressure, select a valve with the appropriate setpoint to meet system design and safety regulations.
