POLTAVA FOUNDRY AND MECHANICAL PLANT

The main purpose of the valve is to work as a shut-off device on pipelines transporting contaminated liquid or even viscous media.

Knife gate valves are used in difficult conditions, under which any other valve is inoperative.

The main purpose of knife gate valves is to shut off the flow of working media characterized by the presence of solid, abrasive particles, increased viscosity, the ability to crystallize, as well as media of powder, granular, fibrous and their slurries, which, for the most part, are chemically active.

Private enterprise "PLMZ" produces high-quality knife (knife) gate valves with a nominal diameter from DN / DU 250 to DN / DU 1200. Gate valves of our production can be both pressure and non-pressure, but both of them have a double-sided seal, which increases the reliability of our products.
