Product Introduction
Ceramic Lined Gate Valve mainly has two types of structure, bolted bonnet type for low pressure ratings and pressure seal bonnet for higher pressure. It uses high hardness, high strength and high purity 99% Al2O3 ceramics, with good corrosion and abrasion resistance, which has longer service life than general metal seated wedge gate valves.
Features
Ceramic Lined Gate Valve has two ceramic sealing rings which are inserted to both sides of wedge gate. Also, it has reasonable structure with reliable sealing and compact appearance. It has abrasion resistance, corrosion resistance, good friction resistance and long service life. It not only improves the use of energy efficiency, increases the safety of production equipment, but also can provide a clean and safe working environment.

Typical Applications:
For some very hard particles or serious erosive mediums, general metal seated wedge gate valves will be washed out and damaged easily due to the abrasion and or corrosion. As a professional and experienced ceramic valve manufacturer, SQ develops ceramic wedge gate valves to solve the corrosion and abrasion problems for wedge gate valves.
SQ ceramic wedge gate valves are very suitable for those mediums contain fibers and hard solid particles, such as below listed typical applications:
1. Mining slag
2. Coal washing
3. Ash Slurry
4. Suspension
5. Oil with particles
6. Catalyst
