Knife gate valves DN50 - DN1800 CYL Knife Valves S. L.

Knife gate valves DN50 - DN1800 CYL Knife Valves S. L. (Spain)
Knife gate valves are used in severe conditions under which any valve is inoperative.
The main purpose of knife gate valves - overlapping stream environments characterized by the presence of hard, abrasive particles, high viscosity, the ability to crystallize, and environments powdery, granular, fibrous and slurries, which, for the most part, are chemically active.
Used knife gate valves on pipelines waste water, pulp, wood and fruit pulp, mining dust, grain, shredded textiles, heavy oil, syrups and brines, polymer chips, cement and so on, knife Gate valves used in the pulp and paper industry, oil refineries, water treatment plants, chemical industry. They can be used on poultry farms, and mineral processing plants and mines.
