Temperature Valve Afriso ATV 555 DN32 Rp1 1/4 kvs 9 55°C (S)A

The Afriso ATV 555 DN32 Rp1 1/4 kvs 9 set for 55°C is a temperature-operated valve designed for hydraulic balancing and automatic temperature control in heating systems. It regulates flow according to medium temperature, providing stable temperature control for radiators, underfloor heating circuits and boiler loop protection in residential and commercial installations. The valve body is sized DN32 with a female Rp1 1/4 connection and offers a kvs flow coefficient of 9 for predictable hydraulic behaviour in typical heating installations.

Advantages

This temperature valve combines hydraulic balancing and temperature-dependent flow control in a single compact component, reducing the need for separate devices. The kvs 9 characteristic ensures consistent and calculable flow rates while the set temperature of 55°C provides reliable operation for medium-temperature circuits. The Rp1 1/4 female connection and DN32 body size fit common piping layouts, facilitating installation and replacement in existing systems.

Suitable for

• Radiator circuits in residential and commercial buildings
• Underfloor heating circuits requiring hydraulic balancing
• Boiler loop protection and temperature limiting in heating plants
• Mixing or diverter circuits where temperature-dependent flow control is required

Key specifications

• Nominal diameter: DN32
• Connection type: female Rp1 1/4 thread
• Flow coefficient (kvs): 9
• Set temperature: 55°C
• Function: temperature-operated valve for hydraulic balancing and automatic temperature control
• Application medium: heating system water/glycol mixtures (as appropriate for system design)

How to use

Install the valve in the heating circuit at the location where temperature-dependent flow regulation is required, observing flow direction markings and piping standards. Connect to DN32 piping using the Rp1 1/4 female thread and ensure proper sealing of threaded joints. Commission the system and verify the valve actuates at the set temperature of 55°C, making any necessary adjustments elsewhere in the hydraulic system to achieve desired temperature distribution and balance.

Usage recommendations

For reliable performance, install the Afriso ATV 555 in accessible locations for inspection and maintenance, protect the valve from freezing and excessive contamination, and follow system manufacturer guidelines for antifreeze concentration if glycol is used. Periodic system checks and flushing as part of regular heating system maintenance help preserve the valve's function and hydraulic balance.
