## Long description

GIACOMINI R88IY003 is a single-piece service valve designed for heating and plumbing systems. Finished in brass, the unit combines an automatic air vent with a shut-off function in a compact inline body supplied as one piece. It is intended for installation in residential and light commercial pipework where easy isolation, air removal and maintenance access are required. Pack quantity: 1 pc.
Advantages
The valve integrates an automatic air vent and a shut-off valve in a single compact body, reducing installation time and the need for additional fittings. A brass finish provides corrosion resistance and durability in typical domestic heating and plumbing environments. Supplied as one piece, the unit simplifies mounting and alignment and minimizes potential leak points compared with multi-component assemblies.
Suitable for
 Residential heating systems (radiators, underfloor heating)
 Domestic hot water circulation lines
 Small commercial boiler plant and distribution manifolds
 Maintenance points where isolation and automatic air release are needed
Key specifications
 Function: combined automatic air vent and shut-off valve
 Construction: single-piece inline body
 Material/finish: brass
 Application: heating and plumbing pipework
 Supply: single unit (1 piece)
How to use
Install the valve inline at an appropriate point in the system where air accumulation is likely or where isolation is required for service. Ensure correct flow orientation and secure connections to compatible pipe fittings using recommended sealing methods for brass fittings. After installation, operate the shut-off function to isolate the circuit for maintenance. The automatic air vent operates without manual intervention to release trapped air; if manual bleeding is required, follow the system manufacturer’s procedure.
Usage recommendations
Install the valve in an accessible position with the vent in a vertical orientation where possible to ensure reliable air separation. Use with compatible pipe materials and follow local plumbing codes. Periodically inspect for signs of wear or deposits and test the shut-off function during scheduled maintenance.
