Set KLASIK OPTIMA - tri-axial - 1/2" x M 24, AL 16 x 2 mm - inox

Product detailed description

This tri-axial set is commonly used in residential and commercial sanitary installations where precise temperature control and durable connections are required. The set is suitable for integration into heating and plumbing systems, particularly in bathrooms and wet areas. It provides a complete solution for connecting sanitary fixtures to the main water supply, ensuring reliable operation under standard domestic conditions.

Installers working in new builds or renovations will find this set ideal for its compatibility with ALPEX multi-layer piping and standard copper tubing. The tri-axial design allows for flexible installation in tight spaces, and the inclusion of a thermostatic insert ensures stable temperature regulation. The set is designed for use in systems operating at up to +100 °C and PN 10 pressure, making it suitable for both hot and cold water applications.

Technical parameters

Installation and connection

The set includes a thermostatic head, tri-axial valve, and fittings for 1/2 inch and M 24 connections. The ALPEX 16 x 2 mm tubing is connected using the provided fittings, which are designed for secure and leak-free installation. The tightening torque for IVAR.DF 03 fittings is 25–35 Nm, and for IVAR.DF 01 fittings it is 30–40 Nm. Installers should ensure that all connections are tightened to the specified torque values to prevent over-tightening or under-tightening, which can lead to leaks or damage to the components.

Common installation mistakes include using incorrect tightening torque and failing to verify the compatibility of the fittings with the ALPEX tubing. It is important to check that the tubing is correctly inserted into the fittings and that the sealing surfaces are free from debris before tightening. The set is not suitable for use with other types of piping unless specified in the manufacturer’s technical documentation.

Compatibility and accessories

This set is designed for use with ALPEX 16 x 2 mm multi-layer tubing and standard copper piping. It includes all necessary components for a complete installation, such as the thermostatic head, valve, and fittings. No additional accessories are required for standard installations. The set is compatible with other IVAR OPTIMA components for consistent system integration.

Technical background for designers

The tri-axial valve operates by allowing independent adjustment of hot and cold water flows, with the thermostatic insert regulating the mixed temperature. The brass CW617N material provides good corrosion resistance and mechanical strength, while the surface treatment enhances durability. The set is designed to integrate into standard heating and plumbing systems, with the pressure and temperature ratings ensuring reliable performance. The use of ALPEX tubing helps reduce thermal expansion effects and improves system stability.

Service and operation

Regular inspection of the connections and thermostatic insert is recommended to ensure continued performance. The tightening torque should be verified periodically, particularly after the initial installation. No specific service intervals are provided in the technical documentation, but any signs of leakage or temperature instability should be investigated promptly. The set is designed for long-term operation with minimal maintenance requirements.

Frequently asked questions
