## Summary description

Afriso thermostatic valve ATV 553 is a DN32 (Rp1 1/4") valve with kvs 9 and a 45°C temperature setting for automatic flow control in heating systems. Designed to maintain a preset medium temperature, it regulates flow based on thermal actuator response. Suitable for district heating substations, radiator circuits and industrial heat distribution where stable outlet temperature is required.

## Long description

Afriso thermostatic valve ATV 553 DN32 Rp1 1/4" kvs 9 45°C is a compact automatic temperature control valve intended for maintaining a preset medium temperature in closed heating and heat-distribution systems. The valve combines a DN32 nominal diameter with a flow coefficient kvs 9 and a fixed 45°C setpoint, using the thermal actuator to regulate flow and stabilize outlet temperature. It is designed for installations where steady medium temperature is required, such as district heating substations, radiator circuits and industrial heat distribution manifolds.
Advantages
The thermostatic design provides automatic flow control without continuous manual intervention, reducing temperature fluctuations in the downstream circuit. With a DN32 connection and a kvs 9 flow coefficient, the valve supports medium flow rates while keeping pressure loss and hydraulic impacts predictable. The fixed 45°C setting simplifies commissioning for systems that require a constant maximum outlet temperature and reduces the need for additional control electronics. Construction materials and connection dimensions follow common heating-industry standards, facilitating integration into existing piping layouts.
Suitable for
District heating substations and hydronic heat exchangers
Radiator circuits and convector loops requiring temperature limitation
Industrial heat distribution manifolds with preset outlet temperature needs
Retrofit projects where automatic temperature regulation is needed without complex control systems
Key specifications
Nominal diameter: DN32 (Rp1 1/4")
Flow coefficient: kvs 9
Fixed temperature setpoint: 45°C
Function: thermostatic automatic flow control to maintain preset medium temperature
Application: hot-water heating and heat distribution systems
How to use
Install the thermostatic valve in the supply or return line according to the flow direction marked on the body, using standard Rp1 1/4" threaded connections. Ensure correct orientation and sufficient straight pipe runs upstream and downstream to provide stable flow conditions. Commission the system by flushing and filling according to the hydronic system procedure, then verify that the outlet temperature stabilizes near the 45°C setpoint under expected load conditions. No external control signal is required for the thermostat to operate; the thermal element reacts to medium temperature and modulates the valve opening accordingly.
Usage recommendations
Use the valve within the recommended operating temperature and pressure limits of the heating system. Combine with appropriate strainers, shut-off valves and air vents during installation to protect the thermostatic element from particulate contamination and ensure reliable operation. For systems with variable demand, verify hydraulic balancing to avoid excessive pressure differentials that could affect regulation accuracy.
