## Summary description

Angular radiator valve by Herz with 3/8" connection, model 1552420. Designed for installation on radiators to control water flow and isolate sections of a heating system. Suitable for use in central heating circuits, replacement and repair of radiator connections, and maintenance tasks requiring a compact angled valve with standard 3/8" fittings.

## Long description

Herz 3/8" radiator angle valve is a compact angular valve designed for installation on radiators to control water flow and to isolate sections of a central heating system. The valve features a right-angled body and standard 3/8" connection that fits common radiator tailpieces and allows straightforward replacement or repair of existing radiator connections. Its construction is intended for reliable operation in residential and light-commercial heating circuits where a compact angled solution is required.
Advantages
The angled design saves space behind the radiator and provides easier access for shut-off and servicing compared with straight valves. A standardized 3/8" connection ensures compatibility with widely used radiator fittings, simplifying replacement and maintenance. The valve body is manufactured to meet common durability and pressure requirements for central heating systems, offering stable flow control and isolation when carrying out repair or replacement tasks.
Suitable for
Replacing or repairing radiator connections with 3/8" fittings
Controlling water flow to individual radiators in central heating circuits
Isolating radiator sections for maintenance or system balancing
Use in compact installations where angled connection is needed
Key specifications
Connection type: angled radiator valve with 3/8" threaded connection
Application: shut-off and flow control for radiators in central heating systems
Orientation: 90° (right-angle) body for space-saving installation
Compatibility: designed for standard radiator tailpieces and fittings with 3/8" interface
Material characteristics: metallic valve body suitable for typical heating water environments
How to use
Shut down the heating system or isolate the circuit before replacing or installing the valve. Remove the existing connection or prepare the radiator tailpiece, then thread the Herz 3/8" angled valve onto the radiator fitting by hand and tighten with an appropriate wrench until secure, taking care not to overtighten. After installation, pressurize the system and check for leaks at the connection points. Use the valve to shut off water flow to the radiator or to regulate flow as needed for balancing or maintenance.
Usage recommendations
Use compatible sealing material or factory-specified gaskets on threaded connections and perform a leak test after pressurizing the system. For safe work, follow local plumbing and heating regulations and, when in doubt, have installation or maintenance performed by a qualified heating technician.
