Cast Iron Slurry Knife Gate Valve

Let Us Be Your Flexgate Manual Slurry Knife Gate Valve Supplier

Red Valve 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.

Flexgate Valves of 3"-12" are provided with standard handwheel mechanisms featuring cast iron handwheels, machined 303 stainless steel stems with yoke sleeves and thrust washers designed to reduce operating torque. Flexgates 14” and larger feature fabricated (tubular) handwheels. It is recommended that manual Flexgate Valves 12" and larger be specified with a 4:1 bevel gear actuator to reduce rim pull. Pneumatic and electric operators are available.
