Unidirectional knife gate valves of PA 540 series
This series is represented by single-acting valves with elastomeric or metal-on-metal seats. Solid cast body of cast iron or various steel grades with knife guides and sealing wedges, high quality knife with specially profiled edge ensure high quality and long service life of these valves.
PA 540 series is used for transportation of liquids with suspended particles content up to 5% or fibrous inclusions up to 35%, as well as gravity feed of dry granular and powdery substances (for these media, it is recommended to install the valve so that the arrow on the body points in the direction opposite to the flow direction).
PA 540 series valves are widely used in the following industries:
– paper-and-pulp industry;
– mining industry;
– chemical industry;
– housing and utilities;
– treatment plants, sewerage networks;
– food industry;
– bulk product transportation.
