Non-freezing valve - 1"; 10bar; 0 °C ÷ 65 °C IVAR.108

Product detailed description

Non-freezing valves are essential in systems where ambient temperatures can drop below freezing. These valves are commonly used in heat pump installations, irrigation systems and plumbing circuits to prevent damage from ice formation. Installers working in residential, commercial and industrial settings may encounter these valves in central heating systems, underfloor heating loops or outdoor water circuits. The valve is designed to allow fluid flow when the temperature is above freezing and to close automatically when temperatures fall below 0 °C, protecting the system from blockages and pipe damage.

Correct selection and installation of non-freezing valves are critical for system reliability. The valve must be compatible with the system's pressure and temperature range, and its connection type must match the existing piping. In heat pump systems, these valves are often installed in conjunction with circulation pumps and expansion vessels to ensure stable operation under varying conditions.

Technical parameters

Code	108601
Brand	IVAR

The valve is rated for a maximum working pressure of 10 bar and operates within a temperature range of 0 °C to 65 °C. These parameters are essential for determining compatibility with the system's hydraulic and thermal conditions. The 1 inch connection size ensures it can be integrated into standard piping systems without requiring additional adapters or modifications. The temperature range is particularly important for ensuring the valve functions correctly in both heating and cooling modes of heat pump systems.

Installation and connection

The valve is installed in a straight section of pipe with a 1 inch connection. It is important to ensure that the valve is oriented correctly, with the direction of flow indicated on the body. The installation should be carried out in a location where the valve can be easily accessed for inspection and maintenance. Common installation mistakes include incorrect orientation, which can prevent the valve from operating as intended, and failure to check for proper sealing at the connection points. Installers should verify that the system pressure does not exceed the valve's maximum rating of 10 bar and that the operating temperature remains within the specified range.

Compatibility and accessories

This non-freezing valve is compatible with a range of heat pump systems and plumbing circuits. It is commonly used in conjunction with circulation pumps, expansion vessels and temperature sensors to create a fully functional system. When installing, it is important to ensure that all components are compatible in terms of pressure, temperature and connection type. Additional accessories such as unions, pipe fittings and insulation may be required depending on the specific installation requirements. Related products include other components from the IVAR.HP ATEC and ITEC series, which are designed for use in similar applications.

Technical background for designers

The non-freezing valve operates using a temperature-sensitive mechanism that responds to ambient conditions. When the temperature drops below 0 °C, the internal mechanism closes the valve to prevent water from freezing and causing blockages. The materials used in the valve are selected for their durability and resistance to corrosion, ensuring long-term reliability in a variety of environments. The valve is designed to integrate seamlessly into existing systems, with its 1 inch connection size and pressure rating making it suitable for both new and retrofit installations. The service life and efficiency of the valve are influenced by factors such as the quality of installation, system pressure and the presence of contaminants in the fluid.

Service and operation

Regular inspection of the valve is recommended to ensure it is functioning correctly. Installers should check for signs of wear, leakage or blockage and verify that the valve opens and closes as expected. No specific service intervals are provided in the brief, but it is advisable to inspect the valve during routine system maintenance. If the valve fails to operate correctly, it should be replaced immediately to prevent potential damage to the system. The valve should be kept clean and free from debris to ensure optimal performance.

Frequently asked questions

Can this valve be used in a heat pump system?
Yes, the valve is suitable for use in heat pump systems. It is designed to operate within the temperature and pressure ranges typical of such systems.

What is the maximum pressure the valve can handle?
