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.

Actuated Flexgate Red Valve’s Flexgate Valves are available with pneumatic, electric or hydraulic actuators. Other options include limit switches, solenoids and air regulators. The actuated Flexgate provides long-term abrasion resistance under high-cycle conditions. The valve self-cleans each time it is cycled and is ideal for automated operations.
