Ceramic Knife Gate Valve
The ceramic knife gate valve is specially developed for the two-phase flow of solid and liquid. Taking engineering ceramics as the main material for throttling element, ceramic gate valve is widely used in coal washing industry, steel industry and mining industry.
Features
1. The sealing surface of the knife gate valve is made of toughened ceramics with abrasion resistance and long service life.
2. The knife gate valve body has shorter structure length than that of the wedge gate valve. The light weight is conducive to easy installation of the ceramic knife gate valve.
3. According to customer's requirement, the bottom of the disc can be permeated with WC. So, the cavitation and erosion to the disc bottom can be avoided when the valve is opened slightly to realize the throttling.
