## Summary description

Check valve by kfa², model 710-010-20, 3/4" connection with a brass piston (grzybek). Designed to allow one-way fluid flow and prevent backflow in plumbing and heating systems. Suitable for installation in water supply, central heating circuits, and similar applications where reliable non-return function and corrosion-resistant brass sealing are required.

## Long description

Check valve kfa² 3/4" with brass piston model 710-010-20 is a one-way non-return valve designed for plumbing and heating systems. The valve features a brass piston sealing element that ensures corrosion resistance and reliable prevention of backflow. Intended for installation in water supply lines, central heating circuits and similar installations, the valve supports steady flow direction and protects systems from reverse flow and pressure-related disturbances.
Advantages
The brass piston provides durable sealing and improved resistance to corrosion compared with non-metallic components, while the compact 3/4" design allows installation in tight spaces. The valve's straightforward mechanical construction ensures low maintenance and consistent performance over time. Materials and design are suitable for potable water and heating media within standard temperature and pressure ranges common for residential and commercial systems.
Suitable for
 Domestic and commercial water supply lines
 Central heating circuits and return lines
 Boiler protection to prevent backflow
 Pumping systems where one-way flow is required
 General plumbing applications requiring corrosion-resistant sealing
Key specifications
 Connection size: 3/4" (female/male depending on installation)
 Sealing element: brass piston
 Function: one-way non-return valve to prevent backflow
 Typical media: potable water, heating water
 Construction: metal body with brass sealing component for corrosion resistance
How to use
Install the check valve in-line with the arrow or flow direction indicated on the body, ensuring the brass piston faces the downstream side. Ensure connections are properly sealed using appropriate thread sealant or tape compatible with potable water systems. Tighten fittings to manufacturer-recommended torque to avoid deformation. After installation, pressurize the system gradually and inspect joints for leaks; verify correct one-way operation by observing flow and absence of reverse flow when the system is off.
Usage recommendations
Regularly inspect the valve during routine maintenance intervals; check for mineral deposits or debris that could inhibit movement of the brass piston. For installations with high sediment content, consider adding a serviceable strainer upstream. Replace the valve if signs of persistent leakage or mechanical sticking occur. Ensure compatibility of materials with system media and operating temperatures.
