## Summary description

Angle check valve Comap 428204P for 1/2" pipe connections, equipped with adjustable flow setting and flow shut-off function. Designed to prevent backflow while allowing controlled regulation of medium flow. Suitable for heating and plumbing systems where space is limited and reliable non-return with shut-off is required.

## Long description

Angle check valve Comap 428204P — 1/2" with flow adjustment and shut-off is a compact non-return valve for 1/2" pipe connections, designed to prevent backflow while allowing controlled regulation of medium flow. The valve integrates an adjustable flow setting and a shut-off function in a right-angle body, making it suitable for installations with limited space. It is intended for use in heating and plumbing systems where reliable prevention of reverse flow and the ability to isolate or throttle the flow are required.
Advantages
The angle design reduces the required installation footprint and simplifies piping runs in confined spaces. Integrated flow adjustment enables fine-tuning of system balance without additional throttling elements. The shut-off feature allows isolation of the circuit for maintenance or replacement without draining larger sections of the system. Constructed from corrosion-resistant materials, the valve offers durable operation under typical heating and potable water conditions.
Suitable for
 Domestic and commercial heating circuits
 Hot and cold water plumbing installations
 Hydronic balancing and flow regulation in compact assemblies
 Applications requiring combined non-return and isolation functions
Key specifications
 Connection size: 1/2" (angle configuration)
 Functionality: non-return (check) valve with adjustable flow and shut-off
 Mounting orientation: angle/right-angle body for space-saving installation
 Flow control: integrated adjustable throttling mechanism for precise flow setting
 Operational media: water for heating and plumbing systems
 Typical applications: heating circuits, potable water systems, hydronic balancing
How to use
Install the valve in-line with the indicated flow direction to ensure proper non-return operation. Use standard fittings for 1/2" pipe connections and ensure joints are sealed according to local plumbing practice. Set the flow adjustment to the required position by turning the adjustment mechanism while the system is at operating conditions or during commissioning, observing flow or pressure indicators as applicable. Use the shut-off function to isolate the downstream circuit when performing maintenance or replacing components; verify that the system is depressurized before disassembly.
Usage recommendations
Regularly inspect the valve for signs of leakage or wear and confirm the adjustment setting during periodic system balancing. When installing in heating systems, flush the circuit to remove debris before final commissioning to reduce the risk of damage to the internal mechanism. Follow applicable local codes and manufacturer instructions for compatible sealing materials and tightening torques.
