SLV EN 2 PN ANSI.5 Class 0 AS 2 Table D AS 2 Table E Stafsjö s knife gate valve SLV is bi-directional and designed for the most demanding slurry and abrasive applications. It is a full bore valve with minimal seat cavity for maximum flow capacity. SLV is a modular design consisting of a compact epoxy coated one or two piece valve body in nodular iron. SLV s unique seat construction guarantees excellent operation together with abrasive media. Stafsjö s unique box packing, TwinPack, together with a bottom scraper gives tight sealing and assures extended operational reliability. SLV s seats give it its unique abilities to perform for extended periods on the most difficult abrasive fluids; they are flexible in an axial way. When the valve is fully open the gate is completely clear of the seat/lining allowing it to form a continual liner from inlet to outlet protecting the internal parts from the fluid. When the valve closes the gate forces its way between the two seats. They are displaced axially forming a seal with the gate until it forms a complete closure of the flow port from both directions and isolating the body cavity from the fluid. The seats also form a sealing face on the valve flanges saving the need for gaskets while reinforcing rings are embedded in them to ensure position, shape and strength for long life. Optional accessories for the SLV are bottom cover, locking pin and stem protection. When using bottom cover flushing of the bottom ports of the body through the existing parts is recommended. For security a locking pin can be mounted in open or closed position through the beams and the gate. The SLV-valve is also available in ATEX-design (ATEX // EC II cat 3 G/D for zone 2 and ).
