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 94/9/
EC II cat 3 G/D for zone 2 and 22). Please contact Stafsjö or
your local representative for advice and information.
