About SLF
Stafsjö’s heavy duty SLF is a push through slurry knife gate valve with superior flow characteristics, offering reliable and bi-directional shut-off performance in the most abrasive and demanding mineral processing applications.
The SLF valve is modular designed and it can easily be customized with actuators and related automation accessories to different process conditions. The valve is also available with mechanical lock out. As standard, the SLF is supplied with a flanged robust precision machined nodular iron valve body up to DN 400 and larger sizes features heavy duty two-piece fully lugged versions. The strong duplex gate is special grinded with purpose of reducing the friction when it cycles through the valve’s rubber seats.
In addition to this slurry valve Stafsjö also offers the compact SLV up to DN 900/36″ and two high pressure versions, the SLH and SLX, available in pressure rating up to 50 bar/725 psi.
