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.
