General Overview

Pneumatic Stainless Steel Ceramic Lined Double Disc Gate Valve is mainly used in feeding and dumping dry powder and the transport pipeline. It adopts toughening ceramic as shut-off and wear-out resistance material, designed with pressure self-sealing and valve disc auto-rotate construction. The sealing surface within the dry powder gains enhanced wear resistance during frequent opening and closing, ensuring high sealing performance requirements and long working life.

Frequently Asked Questions
Q1: What are the primary advantages of ceramic lining in these valves? A: Ceramic lining provides exceptional resistance to abrasion and corrosion, significantly extending the valve's life when handling abrasive dry powders.
Q2: Can the face-to-face dimensions be customized? A: Yes, the "L" dimension and other face-to-face specifications can be customized to fit your specific pipeline requirements.
Q3: Is the valve suitable for high-frequency operations? A: Absolutely. The auto-rotating disc design and self-sealing construction are specifically engineered to handle frequent opening and closing without losing sealing integrity.
Q4: What types of actuators can be used? A: This model is standard with a pneumatic actuator, providing fast and reliable automated control for industrial systems.
Q5: In what industries is this double disc gate valve commonly used? A: It is widely used in power plants (ash handling), cement manufacturing, and mining or dressing works for dry powder transport.
Q6: Does it support bi-directional sealing? A: Yes, the double disc structure combined with internal springs allows for effective bi-directional sealing even at lower pressures.
