Kromschroder Manual valve AKT80F160G 03152349

This is a manually operated flanged ball valve from Kromschroder, model AKT80F160G (SKU 03152349). It has a nominal diameter of 80 mm and is designed for an operating pressure up to 16 mbar. The body is made of cast iron/steel and carries European certification for use with gaseous fuels. Its full-bore, cast body design allows unobstructed flow when open, and it is intended for isolation in a gas supply line.

For selecting a replacement manual valve of this type, match the nominal diameter and flange standard, the maximum operating pressure rating, and the body material. Also verify compatibility with the gas type, as seat and seal materials differ. Measure flange dimensions and bolt-hole spacing, and note whether the valve is unidirectional. The valve must be installed in accordance with flow direction markings, and the stem seal and O-ring should be inspected before installation.

Common failure modes include a seized actuator, leakage past the stem seal or O-ring, and incomplete shut-off when closed. This can appear as difficulty turning the handle, gas odor near the stem, or pressure downstream even after the valve is closed. Inspect the stem seal and O-ring, verify that the handle gives a clear open/closed indication, and perform a leak test after any maintenance.
