Fabri-Valve 33 PTA Heavy Duty Slurry Valve incorporates a push-through design for heavy slurry service. Full ported valve eliminates turbulence and has no metal parts in contact with media. Sleeves are molded with an integral, fully encapsulated, stiffener ring and are replaceable without disassembling the valve. The valve gate is completely withdrawn from the process flow when in the open position and the seat design is without a cavity where solids usually collect.
