Manual Operated Flexgate
Red Valve’s Flexgate Slurry Knife Gate Valve is built with a
cast iron or fabricated steel body and features a heavy-duty
stainless steel gate. Removable rubber cartridge seats on
either side of the gate provide a bi-directional seal and excellent wear resistance. The seats are metal reinforced and
available in a wide variety of elastomers for abrasion resistance and chemical compatibility. A port at the base of the
valve allows for flushing.
The Flexgate Valve provides a bi-directional shutoff.
A heavy-duty topworks is standard. The relatively simple
design eliminates expensive overhauls, unscheduled
shutdowns and costly replacement parts – the
only replacement parts are the
slurry seats and packing.
