Compact set OPTIMA - straight, CU 15 x 1 mm - chrome

Product detailed description

This compact set is ideal for installation in bathrooms, kitchens and other wet areas where precise control of water flow and temperature is required. It is commonly used in residential and commercial buildings with central heating or hot water systems. The set allows for direct connection to copper or ALPEX multilayer pipes, ensuring reliable performance in environments with fluctuating thermal loads. Installers should ensure that the system design accounts for thermal expansion and contraction of the piping materials.

Proper installation requires accurate alignment between the valve body and the sanitary fixture, and verification of secure mechanical coupling. The set is suitable for both new constructions and retrofit projects where space constraints require compact solutions. The inclusion of a thermostatic insert ensures self-regulating temperature control without requiring external adjustments.

Technical parameters

Installation and connection

Installation begins with verifying the pipe dimensions and ensuring the copper tube is cut cleanly and deburred. The connection size is 1/2 inch for the valve inlet and M24 for the sanitary fixture. Torque tightening is critical: apply 25–35 Nm for the DF 03 fitting and 30–40 Nm for the DF 01 fitting using a calibrated wrench. Incorrect torque can lead to leaks or damage to the sealing surfaces.

Installers should also check that the thermostatic insert is seated correctly and that the valve stem moves freely. Common mistakes include overtightening the fittings, which can distort the brass body, and failing to align the threads properly, which can cause cross-threading. Always confirm the direction of flow indicated on the valve body and ensure the set is installed in the correct orientation.

Compatibility and accessories

The set is compatible with copper tubing of dimensions 15 x 1 mm and ALPEX multilayer pipes. It includes a double cover for aesthetic integration with the sanitary fixture. No additional accessories are required for standard installation, though specific tools such as a pipe cutter and deburring tool are recommended for preparation. There are no alternative or related products listed for this model.

Technical background for designers

The set operates via a thermostatic mechanism that responds to ambient temperature changes, adjusting the flow of hot water to maintain the desired setting. The brass CW617N material provides good corrosion resistance and mechanical strength, making it suitable for long-term exposure to water and steam. The chrome plating enhances durability against surface wear and staining.

Integration into the system depends on correct pipe layout and support to prevent stress on the valve body. The use of non-metallic gaskets and proper sealing compounds is recommended to avoid galvanic corrosion. System efficiency is influenced by the accuracy of the thermostatic response and the quality of the mechanical joints. Thermal cycling over time can affect the sealing integrity if installation tolerances are not maintained.

Service and operation

Periodic inspection of the valve stem and sealing surfaces is recommended to detect early signs of wear or leakage. No scheduled service intervals are specified, but the set should be checked during routine maintenance of the overall system. If the thermostatic function becomes unresponsive or erratic, the insert should be removed and inspected for debris or mechanical failure. Always ensure the system is depressurised before performing any checks or repairs.

Frequently asked questions

Can the set be used with copper and ALPEX pipes together?
Yes, the set is designed for use with both copper and ALPEX multilayer pipes, provided the connection sizes match and the installation follows standard practice for each material.

Is the thermostatic insert interchangeable with other models?
No, the insert is specifically designed for this model and is not interchangeable with other IVAR valves without confirmation from the manufacturer's technical data sheet.

What is the maximum torque allowed for the DF 03 and DF 01 fittings?
The maximum torque is 35 Nm for DF 03 and 40 Nm for DF 01. Exceeding these values may damage the fitting or the valve body.

Can the set be used in steam systems?
No, the set is rated for a maximum temperature of 100°C and is not suitable for steam systems, which typically exceed this limit.
