## Summary description

Angled radiator check valve SCHLOSSER 1/2" x 15 mm designed for soldering connections. This plumbing fitting serves as a one-way valve for radiator systems, preventing backflow and ensuring correct flow direction.

## Long description

Angled radiator check valve SCHLOSSER 1/2" x 15 mm for soldering is a one-way valve designed for radiator heating systems. It ensures unidirectional flow, preventing backflow and maintaining correct circulation in heating circuits. The valve is configured for an angled installation and combines a 1/2" threaded connection with a 15 mm soldering (cupro) connection for integration with copper piping.
Advantages
This angled check valve provides reliable one-way flow control suitable for radiator applications. The combination of a 1/2" threaded inlet and a 15 mm solderable outlet enables a compact, angled installation that reduces space requirements at the radiator connection point. Constructed for compatibility with common copper piping, the valve simplifies plumbing work by allowing secure soldered joints and a threaded mating to standard radiator fittings.
Suitable for
 Domestic and commercial radiator connections with 1/2" threaded fitting and 15 mm copper pipe
 Heating circuits requiring prevention of reverse flow
 Renovations or new installations where an angled connection reduces installation space
Key specifications
 Connection type: angled one-way valve with 1/2" threaded connection and 15 mm soldering connection
 Material compatibility: designed for use with copper pipe (15 mm)
 Function: check (non-return) valve for radiator/heating systems
 Installation orientation: angled fitting to suit radiator inlet/outlet positions
 Application: suitable for hot water heating systems in residential and commercial buildings
How to use
Prepare the copper pipe by cutting and cleaning the end, then position the valve so the flow direction marker (if present) aligns with system flow. Solder the 15 mm connection to the copper pipe using appropriate flux and soldering technique, ensuring a clean, leak-free joint. Thread the 1/2" connection to the radiator valve or adapter and tighten to the manufacturer’s recommended torque; use appropriate sealing material on the threads if required by the installation practice. After installation, pressurize the system and inspect joints for leaks before full operation.
Usage recommendations
Use with compatible radiator fittings and copper piping only; verify flow direction before soldering. Employ qualified personnel for soldered connections and pressure testing to ensure safety and system integrity.
