Valve set Herz angled 1/2" model 1920123 - angled valve assembly for heating and plumbing

Herz angled valve set 1/2" (model 1920123) is an angled valve assembly designed for plumbing and heating systems that require a 90° connection. The assembly is intended for installation on radiators, boilers and domestic water circuits where a compact, angled shut-off or service isolation solution is needed. The valve set is compatible with standard 1/2" pipe connections and is designed to provide reliable flow control and isolation in residential and light commercial installations.

Advantages

The angled configuration allows for space-efficient installation where straight fittings would be impractical. Constructed to industry standards, the valve set provides secure connections and consistent shut-off performance. Its design supports routine maintenance and balancing tasks without the need to drain large sections of the system, and the 1/2" connections align with common plumbing fittings for straightforward integration.

Suitable for

• Radiator connections in residential and commercial heating systems
• Boiler service isolation and maintenance points
• Domestic hot and cold water distribution where angled fittings are required
• Balancing and shut-off applications in retrofit and new-build projects

Key specifications

• Connection type: angled 90° orientation with 1/2" connections
• Application: heating and plumbing systems (radiators, boilers, domestic water)
• Function: shut-off, isolation and balancing
• Installation: suitable for concealed and exposed pipe runs where angled entry is needed
• Materials and construction: corrosion-resistant components designed for standard system pressures

How to use

Install the valve set at the intended connection point following common plumbing practice and local codes. Ensure the pipeline is depressurized and drained as required before removing existing fittings. Fit the valve assembly to the 1/2" supply and appliance connections, tighten to recommended torque for the specific pipe and fitting type, and verify seals. After installation, re-pressurize the system and check for leaks. Use the valve for shut-off during maintenance, and for balancing by adjusting flow where applicable.

Usage recommendations

For long-term reliability, verify compatibility with pipe material and system pressure before installation. Periodically inspect connections for signs of leakage and operate the valve occasionally to prevent seizing. When in doubt, follow manufacturer installation instructions and local regulations for heating and plumbing work.
