## Summary description

Safety/pressure relief valve by SYR, 3/4" connection, set to 6 bar (model 2115.20.150). Designed to protect closed water systems by releasing excess pressure at the specified setpoint. Suitable for use in heating and domestic water systems where a reliable mechanical overpressure protection device is required.

## Long description

The SYR pressure safety valve 3/4" set to 6 bar (model 2115.20.150) is a mechanical overpressure protection device intended for closed water systems. It is designed to open at the specified setpoint to release excess pressure and thereby protect boilers, heating circuits and domestic water installations from unsafe pressure buildup. The valve features a 3/4" threaded connection compatible with common piping fittings used in residential and light commercial systems.
Advantages
The valve provides reliable, purely mechanical pressure relief without electronic components, ensuring operation during power interruptions. Its set pressure of 6 bar offers a clear protection threshold for many heating and potable water systems. The compact construction and standard 3/4" connection simplify installation and replacement in existing installations. Materials and internal design are intended for long-term use in closed water systems, reducing the need for frequent maintenance.
Suitable for
 Domestic hot water systems and cold water circuits requiring overpressure protection
 Residential and small commercial heating systems, including boilers and heat generators
 Hydraulic circuits and closed-loop systems where a fixed 6 bar relief point is acceptable
Key specifications
 Connection size: 3/4" threaded
 Set pressure: 6 bar (fixed)
 Function: mechanical pressure relief for closed water systems
 Application medium: water (heating and domestic water systems)
 Mounting: inline on pressure line with standard threaded fitting
How to use
Install the valve in the pressure line of the closed water system at a location accessible for inspection and discharge. Ensure the connection thread matches the system piping and use appropriate sealing material on the thread per installation standards. Orient the valve so that discharged water can be safely routed to a drain or collection point. Verify system pressure and ensure the valve set pressure of 6 bar is compatible with the system design and any expansion vessels or pressure regulators in place.
Usage recommendations
Regularly inspect the valve and its discharge outlet for signs of leakage, corrosion or blockage. Test system components such as expansion tanks and pressure regulators to avoid frequent valve discharge. Replace the valve if it leaks outside of overpressure events or shows mechanical deterioration. Follow local codes and the system manufacturer's installation guidelines when integrating overpressure protection.
