Pneumatic Double Disc Ceramic Lined Gate Valve

Pneumatic Double Disc Ceramic Lined Gate Valve Product introduction

　China Pneumatic Double Disc Ceramic Lined Gate Valve manufacturer, factory and supplier. Pneumatic Double Disc Ceramic Lined Gate Valve is double-disc anti-abrasion gate valve which uses double discs, single/double-side seal, sealed with ceramic and tungsten steel, with excellent mechanical and wear-resistant properties and hardness up to 60~90HRC. Such design solves the short life time issue due to sealing surface abrasion and erosion by continuous scouring material mixed with compressed air.

Pneumatic Double Disc Ceramic Lined Gate Valve is equipped with a ceramic liner inside the body, contributing to its exceptional performance in dry ash conveying systems and hopper pumps. This type of valve is especially well-suited for high-abrasion industries, such as mining, papermaking, chemicals, etc. The ability of Pneumatic Double Disc Ceramic Lined Gate Valve to withstand high levels of wear and tear makes it a valuable asset in these demanding fields. Moreover, it’s designed to function efficiently at temperatures up to 200℃, further emphasizing its versatility and robustness in various industrial applications.
