The Altecnic 15mm Angled Manual Radiator Valve is a type of plumbing fixture used to manually control the flow of hot water to a radiator in a central heating system. Here’s a breakdown of its features and functions:

• 15mm Connection: Refers to the pipe size the valve is compatible with, which is standard for many home heating systems.
• Angled Design: The valve is angled, meaning the pipe into the valve connects at the bottom and then connects into the radiator at a 90-degree angle.
• Manual Operation: Unlike thermostatic valves, a manual radiator valve only controls the flow of water.
• Application: It is used in domestic central heating systems to manage the heat in individual rooms or spaces by controlling the water flow to specific radiators.

This valve is popular for its durability and ease of use, often found in residential settings where simple on/off control of heating is sufficient.
