Temperature control valve Afriso ATV 556 DN32 Rp1 1/4 kvs 9 60°C (S)A

Afriso ATV 556 DN32 Rp1 1/4 kvs 9 60°C (S)A is a thermostatic temperature control valve designed for hydronic systems. It provides automatic modulation of flow to maintain a preset supply temperature of 60°C. The valve body in DN32 size with Rp1 1/4 threaded connections and a kvs value of 9 is intended for integration into heating circuits, radiator control manifolds and temperature-limited safety circuits in residential and light-commercial installations.

Advantages

The thermostat element and precision spindle enable stable temperature control without the need for continuous manual adjustments, reducing temperature fluctuations in the supply line. The compact DN32 body with Rp1 1/4 threaded connections simplifies retrofitting and new installations. A kvs 9 flow coefficient offers a balance between throughput and control sensitivity suitable for medium flow rates. The valve is built for compatibility with common hydronic components and delivers consistent operation at the specified 60°C setpoint.

Suitable for

• Domestic and small commercial heating circuits
• Radiator and convector temperature control
• Supply temperature limitation to protect downstream components
• Retrofit projects where threaded DN32 connections are required

Key specifications

• Nominal size: DN32
• Connection type: Rp 1 1/4 (female thread)
• Flow coefficient (kvs): 9
• Factory set temperature: 60°C
• Control type: Thermostatic temperature control (mechanical actuator)
• Application: Hydronic heating supply regulation and temperature limiting

How to use

Install the valve inline in the supply or branch pipe using compatible Rp1 1/4 threaded fittings and appropriate sealing methods. Position the thermostat sensing element in the flow so the valve senses the circulating temperature accurately. Ensure the piping is clean and free of debris before installation to prevent valve seat damage. After fitting, verify correct orientation according to flow direction markings and commission the system by bringing it up to operating temperature to confirm the valve maintains the 60°C setpoint.

Usage recommendations

Use the valve in systems with compatible fluid type and temperature range; avoid aggressive fluids and temperatures beyond the rated operating conditions. Periodically inspect the valve and piping for leaks, and flush the system if contamination is suspected. For best results, install strainers or filters upstream to protect the valve internals and follow local codes for heating system commissioning and maintenance.
