ICMA Safety Valve 1/2 inch 2.5 bar F/F

The ICMA safety valve 1/2 inch 2.5 bar F/F is a critical component engineered to protect closed-loop heating systems from the dangers of excessive pressure. By automatically discharging fluid when the internal pressure exceeds the calibrated limit of 2.5 bar, this valve prevents structural damage to pipes, boilers, and other hydraulic equipment, ensuring the longevity and reliability of your installation.

Advantages

This safety valve combines high-quality brass and durable plastic components to provide a robust solution for pressure management. Its precise calibration ensures consistent performance, while the standard 1/2 inch female/female connection allows for straightforward integration into existing heating circuits. The materials used are specifically selected to withstand the thermal stresses of heating systems, offering a dependable safety mechanism that operates automatically without the need for manual intervention.

Suitable for

• Closed-loop central heating systems
• Hot water boilers and storage tanks
• Hydraulic installations requiring overpressure protection

When it may not be suitable

This valve is not intended for use in systems where the operating pressure requirements exceed 2.5 bar or in applications involving corrosive fluids that are incompatible with brass and standard plumbing plastics. It should not be used as a primary flow control valve.

Key specifications

• Connection size: 1/2 inch female/female
• Pressure rating: 2.5 bar
• Operating temperature range: -10°C to 110°C
• Materials: Brass and high-grade plastic

How to use

The valve should be installed in the vertical or horizontal position at the highest point of the heating system or directly on the boiler outlet, ensuring the discharge port is directed safely away from electrical components or areas where escaping fluid could cause harm. Ensure the thread is properly sealed using appropriate plumbing sealant or tape to prevent leaks at the connection point.

What to consider before purchase

• Verify that the 2.5 bar pressure rating matches the safety requirements of your specific heating system.
• Ensure the 1/2 inch female/female connection is compatible with your existing pipework.
• Check that the operating temperature range is suitable for your installation environment.

Usage recommendations

Regularly inspect the valve for signs of leakage or mineral buildup to ensure the discharge mechanism remains functional. It is recommended to have the system checked by a qualified professional during annual maintenance to verify that the pressure relief function is operating within the specified parameters.
