Valve set with thermometers and manual air vents Afriso PROCALIDA 81 273 – two valves

Afriso PROCALIDA valve set 81 273 consists of two valves with integrated thermometers and manual air vents, designed for hydronic heating and cooling systems. The valves provide local temperature readout at the connection point and allow manual bleeding of trapped air to maintain proper circulation. The compact assembly is suitable for installation on radiators, convectors or boiler connections where monitoring and manual venting are required.

Advantages

The valve set combines temperature measurement and air venting in a single compact unit, reducing the need for additional components and simplifying installation. Integrated thermometers give immediate visual feedback on fluid temperature near the valve, enabling quick verification during commissioning and routine checks. Manual air vents permit controlled removal of air pockets to reduce noise and improve heat transfer efficiency without relying on automatic devices.

Suitable for

• Residential radiator connections and individual room heating circuits
• Commercial radiators and convectors in small to medium installations
• Boiler return or supply lines where local temperature monitoring is required
• Systems that require manual air bleeding during commissioning or maintenance

Key specifications

• Type: valve set with integrated thermometer and manual air vent
• Quantity: two valves per set
• Application: hydronic heating and cooling systems
• Functionality: local temperature indication and manual degassing
• Installation location: radiator, convector or boiler connection points

How to use

Install the valve set in accordance with the system layout and local plumbing codes, ensuring correct flow orientation. Read the integrated thermometers to check fluid temperature at the valve position during initial commissioning and periodic inspections. To remove trapped air, open the manual air vent slowly until fluid emerges, then close the vent. Perform bleeding operations with the system at low pressure and follow safety procedures to avoid scalding.

Usage recommendations

Use the integrated thermometers for routine monitoring and the manual vents during commissioning and scheduled maintenance. Verify connections for tightness after installation and re-check temperature readings after system adjustments. If persistent air accumulation or abnormal temperature differences occur, inspect the system for leaks, improper pump operation or design issues.
