Bidirectional knife gate valves with polyurethane seat of PA 560 series
|
PA 560 series knife gate valves are specially designed for reliable operation in pipelines transporting highly abrasive working media with a high content of solid inclusions – sludge, pulp, heavily polluted water containing sand and stones. The gates can be used for abrasive liquid products in the chemical industry and in wastewater systems. One-piece molded soft seat, installed inside the body, consisting of two halves, is made of polyurethane. This elastomer has a very high degree of resistance to abrasion, which allows using PA 560 series valves for a long-term period under the most severe operating conditions. Valves of this series can be used in such industries as: – mining industry; – systems for waste water transportation and treatment; – power stations; – heat power plants; – chemical enterprises.
