Bidirectional knife gate valves with internal rubber inserts of PA 550 series
|
PA 550 series valves are guillotine-type valves intended for use on liquid transportation lines with slurries of solid particles, water containing mud, stones and pulp. The structure of the body and replaceable rubber seats reinforced with a metal core, provides a full-opening cross section without stagnant and cavitation zones and prevents abrasive wear of body parts. The knife of PA 550 series guillotine-type valve ensures reliable shutoff of the working medium flow in both directions. The most widely knife gate valves series PA 550 are used in the mining industry, and also at enterprises of the energy sector.
