Product DescriptionThe Knife Gate ValveThe electro -hydraulic anti-abrasive 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.It works as slurry valves in some coal washing plant .FeaturesThe sealing surface of the knife gate valve is made of toughened ceramics with abrasion resistance and long service life.The knife gate valve body has shorter structure length than that of the wedge gate valve.The light weight is conductive to easy to install of the ceramic knife gate valve.According to customer's requirement,the bottom of the disc can be permeated with WCB. So the erosion to the disc bottom can be avoided when the valve is opened slightly to realize the throttling.ApplicationKnife gate valves feature a knife-shaped gate plate and are widely used for flow control in industries such as coal preparation, slag removal, wastewater treatment, food processing, sanitation, and pharmaceuticals.Technical SpecificationsSize2"~32" DN50~DN800PressureClass 150 PN1.0~PN1.6 MPaBody materialWCB,CF8,CF8M,CF3,CF3M etc.Sealing materialToughened engineering ceramicConnection TypeFlange connection,wafer typeDriving methodElectro-hydarulicDrawings & DimensionsOur engineering team can provide tailored designs to meet specific project requirements.Company ProfileAfter Sales ServiceFAQQ: What is the cause of the leakage at the stem extension?A: There are two reasons, one is the sealing ring damage; Second, the sealing ring wear, aging.Q: How to solve the leakage at the stem extension?A: The solution is to replace the sealing ring.Q: What causes leakage at the valve and pipe connection?A: First, the sealing surface is damaged or contaminated by dirt; Second, gasket failure; Third, the pipe flange pressure is uneven or not pressed.Q: How to deal with leakage at the connection of valve and pipeline?A: The following measures can be taken: repair the sealing surface or clean up the dirt; Replace the gasket; Press the flange bolt evenly.Q: What is the cause of leakage in the valve?A: There is mainly debris on the sealing surface, or the sealing surface is damaged.
