Angle Check Valve Comap 428206, 3/4 inch, brass non-return valve

Angle check valve Comap 428206, 3/4 inch, brass non-return valve is a compact plumbing component designed to allow one-way fluid flow and prevent backflow in domestic and light commercial heating and water systems. The valve has an angled body to fit installations where straight-line space is limited and is constructed from brass for corrosion resistance and durability. It is intended to protect pumps, boilers and sections of piping from reverse flow and to help maintain system pressure stability.

Advantages

The brass construction provides good resistance to corrosion and wear in typical water and heating environments. The angle configuration reduces installation depth and simplifies placement in tight spaces. The valve is designed for reliable one-way flow control and requires minimal maintenance under normal operating conditions. Its compact size makes it suitable for retrofit work as well as new installations in domestic and light commercial systems.

Suitable for

• Prevention of backflow in domestic hot water circuits
• Protection of pumps and boilers in central heating systems
• Installations with limited linear space where an angled valve is required
• Light commercial plumbing and mechanical systems

Key specifications

• Connection size: 3/4 inch
• Valve type: angle non-return (check) valve
• Body material: brass
• Flow direction: one-way
• Typical application medium: potable water and heating fluids
• Installation orientation: angled inline mounting

How to use

Install the valve in the pipework with the flow arrow aligned to the intended flow direction to ensure correct one-way operation. Use appropriate sealing materials on threaded connections and tighten to the torque recommended for the pipe fittings and valve size. Support adjacent pipework to avoid strain on the valve body. After installation, pressurize the system and check for leaks and correct operation; verify that there is no reverse flow when downstream pressure exceeds upstream pressure.

Usage recommendations

Use with clean water or compatible heating fluids and avoid exposure to aggressive chemicals. Periodically inspect for signs of external leakage or corrosion, and verify valve operation during scheduled system maintenance. If the system requires compliance with specific standards or water treatment regimes, confirm material compatibility and suitability for the intended application.
