Kromschroder Manual valve AKT25R50B 03152274

The Kromschroder AKT25R50B is a manual ball valve with a nominal diameter of 25 mm and a Rp 1" internal thread. It is designed for shut-off of gas or air supply in burner systems, with a maximum inlet pressure of 5000 mbar. The valve is made of brass and operates manually with a two-position (on/off) action, featuring a visual open/closed position indicator. It has a net weight of 0.517 kg and dimensions of 178 x 71 x 45 mm, suitable for medium temperatures down to -20°C. This valve is manufactured in Germany.

When selecting a manual ball valve of this type, ensure the connection thread size and type match the existing pipe (e.g., Rp 1"), and that the nominal diameter (DN) corresponds to the pipe size. Verify the maximum working pressure rating is at least equal to the system's operating pressure. Check the housing material compatibility with the medium (e.g., brass for gas, air, or water). Confirm the valve's dimensions allow for proper installation in the available space, and that the handle position indicator is clearly visible for operation.

Common failures of manual ball valves include leakage past the seat when closed, which can allow gas to bypass and pose a safety risk. The handle may become stiff or difficult to turn due to debris or corrosion, preventing full open or closed positions. Visual indicators can become misaligned, giving a false reading of the valve state. Regular inspection for leaks and smooth operation is recommended.
