with handwheelshut-offfor sludge

Red Valve's Series D Flexgate Valve is designed with a cast iron body or fabricated steel body, stainless steel gate and two heavy-duty elastomer cartridge slurry seats. The port is formed by two heavy-duty cartridge elastomer slurry seat halves. The cartridge slurry seats are available in various elastomers for chemical compatibility and abrasion resistance. A flush area at the valve's base provides a clean-out port. The Flexgate Valve provides bi-directional shut off. 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 sleeves and the packing. Flexgate Valves of 3"-12" are provided with standard handwheel mechanisms featuring cast handwheels, machined 303 Stainless Steel stems with yoke sleeves and thrust washers designed to reduce operating torque. It is recommended that Manual Flexgate Valves 12" and larger be specified with a 4:1 bevel gear actuator. The 4:1 bevel gear actuator is available to reduce rim pull and operate the valve. Pneumatic actuators are also available and allow the Flexgate to provide long-term abrasion resistance under high cycle conditions.
