ICMA 91242ADAC Safety Valve 1/2 inch 1.5 bar Male/Female

The ICMA 91242ADAC safety valve is a high-quality pressure relief component engineered specifically for heating systems. This device plays a critical role in maintaining the integrity of your installation by automatically releasing excess pressure that exceeds the 1.5 bar threshold. Constructed with a combination of durable brass and high-grade plastic, it provides a robust solution for protecting boilers and piping networks from potential overpressure damage in both residential and commercial environments.

Advantages

The primary benefit of this safety valve is its reliable performance in safeguarding heating infrastructure. By utilizing a precise 1.5 bar calibration, it ensures that the system remains within safe operating limits, thereby extending the lifespan of connected equipment. The inclusion of both male and female 1/2 inch connections offers versatile installation options, allowing for seamless integration into existing piping configurations. Its resilient construction materials are designed to withstand a wide range of operating temperatures, ensuring consistent functionality under demanding conditions.

Suitable for

• Residential heating systems
• Commercial boiler installations
• Closed-loop hydronic heating circuits
• Protection of piping networks against overpressure

This valve is not suitable for high-pressure industrial steam systems or applications where the operating pressure exceeds the 1.5 bar rating. It should not be used in systems involving corrosive fluids that are incompatible with brass or plastic components.

Key specifications

• Connection size: 1/2 inch male and 1/2 inch female
• Pressure rating: 1.5 bar
• Operating temperature range: -10°C to 110°C
• Materials: Brass and plastic

How to use

The valve should be installed at the highest point of the heating system or directly on the boiler outlet where pressure accumulation is most likely to occur. Ensure that the discharge port is directed toward a safe drainage area to prevent water damage during activation. The installation should be performed by a qualified professional to ensure that the threads are properly sealed and that the valve is oriented correctly according to the flow direction indicated on the body.

What to consider before purchase

• Verify that the 1.5 bar pressure rating matches the requirements of your specific heating system.
• Check the thread compatibility of your existing piping to ensure the 1/2 inch male/female connections are suitable.
• Confirm that the operating temperature range aligns with your system's output.

Usage recommendations: Regularly inspect the valve for signs of leakage or mineral buildup to ensure it remains operational. It is recommended to perform a manual check of the relief mechanism annually to confirm it is not seized and will function correctly in an emergency.
