## Summary description

Inline check valve by kfa² with a 1-inch connection and a brass sealing poppet (model 710-010-25). Designed to allow unidirectional fluid flow and prevent backflow in plumbing and heating systems. Suitable for installations requiring durable corrosion-resistant sealing, such as domestic water lines, boiler circuits, and commercial piping where reliable backflow prevention is needed.

## Long description

The kfa² Check valve with brass seal 1" (model 710-010-25) is an inline unidirectional valve engineered to permit fluid flow in one direction while preventing backflow. Constructed for plumbing and heating systems, this check valve features a brass sealing poppet designed for corrosion resistance and reliable seating. Its 1-inch connection size makes it suitable for domestic water lines, boiler circuits and many commercial piping applications where durable, maintenance-friendly backflow prevention is required.
Advantages
This check valve combines a brass sealing element with a robust inline body to provide consistent sealing performance and reduced risk of corrosion over time. The compact 1" design allows straightforward integration into existing pipework with minimal space requirements. A simple internal mechanism minimizes pressure loss while ensuring rapid closure to prevent reverse flow. Material choices and construction focus on long-term reliability in potable water and heating system environments.
Suitable for
 Domestic cold and hot water supply lines
 Boiler and central heating circuits
 Commercial plumbing systems requiring backflow prevention
 Pumping systems where one-way flow control is needed
Key specifications
 Connection size: 1 inch (inline)
 Sealing material: brass poppet for corrosion resistance
 Function: check valve / non-return valve allowing one-way flow
 Typical applications: potable water, heating circuits, commercial piping
 Construction: compact inline body for easy installation
How to use
Install the valve in-line with the flow direction indicated by the arrow on the body. Ensure pipe ends are clean and free of debris before making connections and apply appropriate fittings or thread sealant compatible with the valve materials. Tighten connections to the recommended torque for the selected pipe fittings to avoid stressing the valve body. After installation, pressurize the system and inspect joints for leaks. Verify correct operation by observing one-way flow and confirming no reverse flow occurs under typical system conditions.
Usage recommendations
To maximize service life and performance, use the valve within the temperature and pressure limits of the system, avoid exposure to aggressive chemicals not compatible with brass, and schedule periodic inspections to check for debris or wear. When used in potable water systems, follow local codes for installation and maintenance.
