ICMA 90149AF05 Thermostatic Mixing Valve 1 inch 30-65C

The ICMA 90149AF05 thermostatic mixing valve is a precision-engineered component designed to regulate water temperature in heating and domestic hot water systems. With a 1-inch connection, this valve provides reliable performance by blending hot and cold water supplies to achieve a stable, user-defined output temperature. Its robust construction ensures durability and consistent operation, making it a critical element for maintaining thermal comfort and safety in residential and commercial plumbing installations.

Advantages

This thermostatic mixing valve offers exceptional temperature stability, ensuring that the water delivered to outlets remains within the desired range regardless of fluctuations in supply pressure or temperature. By maintaining a constant output, it significantly enhances system efficiency and helps prevent the risk of scalding, which is vital for domestic safety. The high-quality materials used in its manufacturing provide long-term reliability and resistance to wear, while the adjustable range allows for versatile application across various heating and water distribution setups.

Suitable for

• Domestic hot water distribution systems
• Central heating installations
• Solar thermal water heating setups
• Preventing scalding in bathrooms and kitchens

When it may not be suitable

This valve is not intended for use in industrial systems requiring extreme flow rates or pressures beyond its technical specifications. It is also not suitable for applications involving aggressive or chemically treated fluids that could damage the internal components of the valve.

Key specifications

• Connection size: 1 inch
• Temperature adjustment range: 30-65C
• Function: Thermostatic mixing of hot and cold water
• Application: Heating and domestic hot water systems

How to use

The valve should be installed by a qualified professional in accordance with local plumbing codes. It is typically placed at the point of distribution or near the water heater. Once installed, the desired output temperature can be set by adjusting the control knob on the valve body. Regular inspection of the valve is recommended to ensure that the internal mechanism remains free of debris and scale buildup, which could affect temperature accuracy over time.

What to consider before purchase

• Verify that the 1-inch connection size is compatible with your existing pipework.
• Ensure the required temperature range of 30-65C meets your specific system needs.
• Check the flow rate requirements of your installation against the valve capacity.

Usage recommendations

For optimal performance and safety, it is recommended to install isolation valves on both the hot and cold water inlets to facilitate maintenance and cleaning without draining the entire system.
