## Long description

Angle check valve Comap 3/8" (model 2428) is a compact non-return valve designed for heating and plumbing installations. It prevents backflow in pipelines and ensures unidirectional flow in radiator branches, boiler circuits and pump lines. The valve fits 3/8" connections and has a robust construction intended for reliable operation in domestic and light commercial systems. Its inline design allows straightforward installation in tight spaces where angular fitting is required.

The valve offers corrosion-resistant materials and a compact form factor that minimizes space requirements while maintaining flow performance. Its non-return mechanism provides consistent protection against reverse flow without manual intervention. The product is compatible with common heating system media and designed for long service life with low maintenance needs.
Suitable for
Domestic radiator connections

Key specifications
Connection size: 3/8"
Type: angle non-return (check) valve
Installation orientation: inline angular connection
Application: heating and plumbing systems
Construction: metal body with internal non-return mechanism
How to use
Install the angle check valve in the intended section of the pipeline with the flow direction oriented correctly according to system flow. Use appropriate sealing tape or joint compound on threaded connections and tighten to recommended torque for the fitting size. Verify leak-tightness after filling the system and bring the system to operating pressure; observe the valve during initial operation to confirm correct non-return function. If installed in pump lines, position the valve to protect the pump from backflow when the pump is off.
Usage recommendations
For reliable performance, avoid installing the valve where debris or high sediment load may accumulate; install upstream strainer or filter if necessary. Perform periodic visual inspections and check for leaks during routine system maintenance. Use compatible fluids and operating temperatures in line with standard heating system practice.
