## Long description

Afriso shut-off valve model 77723 is designed to isolate automatic air vents in heating and plumbing systems. The valve has a 1/2" male (GZ) inlet and a 3/8" female (GW) outlet, allowing direct connection to compatible automatic air vents or fittings. It permits maintenance, inspection or replacement of an air vent without the need to drain the entire system, and provides a secure flow shut-off for residential and light commercial installations.
Advantages
The Afriso shut-off valve provides a compact and robust isolation point that simplifies vent maintenance and reduces system downtime. Its threaded connections enable straightforward installation with common plumbing fittings, and the internal shut-off mechanism gives a reliable seal for temporary disconnection of the vent. The design is suitable for confined installation spaces and supports routine service procedures without full system depressurisation.
Suitable for
Isolation of automatic air vents in hot water heating systems
Plumbing manifolds and branch lines that use 3/8" vent fittings
Service and replacement of vents in residential radiators and distribution units
Small commercial installations where a compact shut-off for vents is needed
When it may not be suitable
This shut-off valve is intended specifically for connection to automatic air vents and similar fittings with matching thread sizes; it is not a general-purpose isolation valve for large-diameter pipelines. It may not be suitable where higher flow capacity, specialised materials for aggressive fluids, or additional certifications are required for industrial process systems.
Key specifications
Inlet connection: 1/2" male threaded
Outlet connection: 3/8" female threaded
Application: isolation of automatic air vents in heating and plumbing systems
Typical installation location: radiator valves, manifolds, distribution units
How to use
Shut off system pressure if required by local practice, then fit the 1/2" male inlet to the corresponding female fitting in the line and secure the 3/8" female outlet to the automatic air vent or adapter. Tighten threaded connections with appropriate tools and apply sealing tape or compound where applicable. To isolate the vent for service, operate the valve’s shut-off mechanism to close flow; after maintenance, reopen and check the vent and surrounding joints for leaks during normal operation.
What to consider before purchase
Verify that the system uses a 1/2" male to 3/8" female interface for the vent connection
Confirm material compatibility with the system fluid and operating temperatures
Check available installation space and orientation requirements in the manifold or radiator area
Usage recommendations
Use appropriate thread sealing on connections, follow local plumbing codes during installation, and perform a leak test after first pressurising the system. Schedule regular inspection of the valve and vent as part of routine heating system maintenance.
