DELCO Z644TC Pneumatic Ceramic Double Disc Gate Valve - Wear Resistant, Ash Conveying
The DELCO Z644TC Pneumatic Ceramic Double Disc Gate Valve is specifically engineered for dry ash pneumatic conveying systems. It features two parallel ceramic discs that rotate against the seat rings during operation. This "rotate-and-grind" action ensures a self-lapping seal, providing unmatched durability against abrasive fly ash, cement, and mining dust.
Features
A heavy-duty pneumatic double disc gate valve with rotating ceramic sealing faces, ensuring superior wear resistance and tight sealing in abrasive pneumatic conveying lines.
✅Ceramic-on-Ceramic Sealing: Utilizing Toughened Engineering Ceramics (HRA ≥ 87) for both the discs and seats, this valve resists the extreme scouring wear of high-velocity dry powders, far outlasting Metal Seated Gate Valves.
✅Double Disc Mechanism: The two parallel discs are spring-loaded to maintain constant contact with the seat rings, ensuring a reliable seal even at low pressures or vacuum conditions.
✅Self-Lapping Rotation: The discs automatically rotate during the opening and closing cycle, preventing localized wear spots and continuously polishing the sealing surfaces for extended life.
✅100% Full Bore: Offers a completely unobstructed flow path when open, minimizing pressure loss and preventing ash accumulation or bridging inside the valve body.
✅Pneumatic Automation: Powered by a robust pneumatic cylinder, it provides fast and reliable cycling for ash hoppers, silos, and pump inlets in thermal power plants.
