## Long description

Inline check valve kfa² model 710-010-32 with a brass plug and 5/4" connection is a compact unidirectional valve designed to prevent backflow in plumbing and heating systems. The valve uses a brass sealing element that provides reliable sealing for potable water and central heating circuits. Built for inline installation, it supports pump protection, system isolation and maintains flow direction without requiring complex fittings.
Advantages
This check valve features a brass plug that ensures durable sealing and resistance to corrosion in common water and heating environments. The 5/4" connection enables straightforward integration into existing pipework and reduces the need for adaptors. Its inline form factor allows compact installation in tight spaces while providing stable unidirectional flow control and minimizing pressure loss.
Suitable for
Domestic cold and hot water distribution lines
Central heating return and supply circuits
Pump discharge lines for backflow prevention
Boiler and heat source protection
Pipework sections requiring system isolation and one-way flow
Key specifications
Connection size: 5/4" inline threaded connection
Sealing element material: brass plug
Application: potable water and central heating systems
Function: non-return (one-way) valve to prevent backflow
Design: compact inline body for installation in confined spaces
How to use
Install the check valve in the pipeline with the flow direction aligned to the arrow on the valve body. Ensure threads and mating surfaces are clean and use appropriate thread sealant or tape rated for potable water systems if required. Tighten to recommended torque for the pipe material to avoid overtightening the brass components. After installation, pressurize the system and inspect for leaks; verify correct operation by observing that flow is allowed in the intended direction and blocked in reverse.
Usage recommendations
For long-term performance, avoid installing the valve where debris or sediment can accumulate; consider adding a strainer upstream if needed. Periodically inspect the valve during routine maintenance of the plumbing or heating system and replace if signs of wear or leakage appear. Use materials and sealants compatible with potable water if the valve is used in drinking water systems.
