## Summary description

Afriso ATV 333 is a temperature control valve for HVAC and hydronic systems, DN25 with Rp1" threaded connection, kvs 9 and set to 45°C. It maintains medium temperature by modulating flow based on setpoint, suitable for radiator circuits, underfloor heating and hot water regulation in residential and commercial installations.

## Long description

The Afriso ATV 333 DN25 Rp1" kvs 9 45°C is a temperature control valve designed for HVAC and hydronic systems. Factory-set to 45°C, it modulates flow to maintain a stable medium temperature in heating and hot water circuits. The valve body with Rp1" threaded connection and DN25 nominal diameter is intended for integration into radiator circuits, underfloor heating manifolds and domestic hot water regulation within residential and commercial installations.
Advantages
The valve provides precise temperature control through proportional modulation of flow, reducing temperature fluctuations in the controlled circuit. Its compact DN25 design and Rp1" threading simplify installation in standard piping systems. A kvs value of 9 ensures appropriate flow capacity for small to medium-sized heating loops, and the factory-set 45°C point offers consistent operation without immediate need for field calibration.
Suitable for
Radiator heating circuits in residential buildings
Underfloor heating manifolds and zone control
Domestic hot water temperature regulation
Small commercial HVAC hydronic loops requiring temperature control
Key specifications
Nominal diameter: DN25
Threaded connection: Rp1"
Flow coefficient (kvs): 9
Factory set temperature: 45°C
Control principle: temperature-modulating valve for proportional flow control
Application: heating and hot water circuits in hydronic systems
How to use
Install the temperature control valve in the flow or return line of the target circuit, ensuring correct thread engagement on the Rp1" connection and appropriate sealing. Position the valve accessible for maintenance and, if present, connect any temperature sensor or actuator following the system design. Once fitted and system pressure tested, allow the valve to modulate flow to maintain the set 45°C medium temperature; adjust system balancing valves and pump speeds as required to achieve stable operation.
Usage recommendations
Use the Afriso ATV 333 in systems with compatible DN25 piping and ensure water quality meets standard heating system requirements. During commissioning, verify correct hydraulic balancing and confirm that the valve operates within its rated flow range. For integration with controllers or sensors, follow manufacturer instructions for compatible actuators and avoid exceeding the valve's pressure and temperature limits.
