Radiator Angle Valve Herz 3/8" – Herz 1552420

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.
