MICRODIAM motorized valve for 50mm distance manifold

Product catalog summary

Technical Specifications
The document outlines the technical features of motorized ball valves, specifically focusing on two main power supply options: 230V 50/60 Hz and 24V 50/60 Hz. The valves are available in two control types: 2-point (ON/OFF) and 3-point (ON/OFF and Modulating). Key specifications include a length of 80 cm, a torque of 5 Nm, a rotation angle of 90°, and a power consumption of 3.9 VA. The valves are designed for indoor use, protected from frost, with an operational temperature range of +5°C to +50°C and a maximum humidity of 95% without condensation. The protection degree is IP44, and the insulation degree is II, with the external shell made of polyamide PA 6 with 30% fiberglass. The valves are CE certified.

Applications
These motorized ball valves are suitable for zone heating systems, systems using alternative energy, general automation systems, and distribution manifolds with a minimum span of 50 mm.

Versions and Codes
The document lists different versions of the valves with corresponding codes for 24V and 230V power supplies, such as MR242N and MR222N for 2-point control, and MS242N and MS222N for 3-point control. An optional auxiliary opening microswitch can be added by appending '1' to the code.

Electrical Connections
Detailed examples of electrical connections are provided, illustrating how to connect the pump stop with various combinations of 2-point and 3-point actuators. The document emphasizes the importance of making power supply connections inside a branch box with at least IP54 protection.

Pressure and Fluid Specifications
The valves are designed to handle a nominal operating pressure of 16 bar and a maximum operating differential of 16 bar. They are compatible with water and fluids that are compatible with EPDM and Teflon, with a temperature range from +5°C to +100°C.

Zone Adjustment
The document discusses zone adjustment options with and without climate pre-adjustment, highlighting the efficiency of modulating zone adjustments. It provides efficiency values for different types of radiators and radiant panels.

Example Specifications
An example specification is provided for a MICRODIAM actuator with a 2-point ON/OFF electric control, including details such as nominal torque, power supply, operating time, and degree of protection. The associated ball valve specifications include material, seals, port type, pressure rating, and connection details.

Overall Dimensions
The document concludes with a table of overall dimensions for different valve models, specifying measurements for various components.
