## Long description

Afriso Safety Relief Valve AED 3/4x1" DN20 with a set pressure of 1.5 bar is a compact overpressure protection device intended for installation in heating, domestic hot water and small industrial systems. The valve opens at the nominal set pressure to safely discharge excess pressure from piping and equipment, helping to prevent damage and ensure system integrity. The threaded 3/4x1" connection provides straightforward mechanical mounting and integration into existing piping layouts.
Advantages
The valve provides reliable pressure relief at a fixed 1.5 bar setting and is sized DN20 to suit small to medium circuits. Its threaded 3/4x1" connection simplifies replacement or retrofit without the need for specialized adapters. The compact design allows installation in confined spaces and is compatible with common heating and domestic hot water installations. Constructed for stable operation, it discharges excess pressure quickly to reduce the risk of component stress and system leaks.
Suitable for
 Residential and commercial heating systems
 Domestic hot water installations
 Small industrial process circuits requiring overpressure protection
 Retrofit or replacement projects where a DN20 threaded relief valve is required
Key specifications
 Nominal size: DN20
 Connection type: threaded 3/4x1"
 Set pressure: 1.5 bar
 Function: spring-operated safety relief valve for pressure discharge
 Typical application fluids: heating water and domestic hot water
 Compact form factor suitable for limited installation space
How to use
Install the valve in accordance with system flow direction and local codes, ensuring the outlet is routed or positioned to safely discharge released fluid. Tighten the threaded connection to the recommended torque for the pipe material and use appropriate sealing method for the thread type. The valve operates automatically: when system pressure reaches the 1.5 bar set point the valve opens to discharge excess pressure and re-closes as pressure falls below the set point. Periodic visual inspection and functional testing according to maintenance schedules and applicable standards are recommended to confirm reliable performance.
Usage recommendations
Ensure the relief valve is installed where discharged fluid will not cause damage; provide a safe discharge path or drain. Avoid placing isolation valves downstream of the relief valve outlet. Verify compatibility of the valve materials with the system fluid and follow applicable regulations and manufacturer instructions for testing and maintenance.
