Ceramic Knife Gate Valve

Pneumatic Ceramic Double Disc Gate Valve FREE-Valves Pneumatic Ceramic Double Disc Gate Valve is mainly used in feeding and dumping the dry powder and the transport pipeline, which not only adopt toughening ceramic as shut off and wear out resistance material, but also design construction of autofrettage pressure self-sealing and valve disc auto-rotate, so as to the sealing surface within the dry powder get more wear resistance in process of opening and closing frequently, thereby, which guarantee the high requirements of sealing performance of this valve and long working time. Features: Sealing pair is made of structural ceramicswhich have perfect performance to resist wear and flushing. Two-side sealing can realized due to double plate structure of the pneumatic ceramic double disc gate valve It inserts spring between double valve discs to ensure self- sealing through bi-directional flexible preload pressure of spring, having characteristics of low pressure bi-directional sealing and without dust clogging phenomenon in the process of the opening and closing of valve. The valve has characteristics of good se The standards of flange end sASME B16.5GB/T9113 ominal Pressure1.0MPa,Cla ss150 Size RangDN1 50DN 300, NPS6 NPS12 Connection typeFlange Working Temperation250 Operating TypePneumatic, manual Sealing surface materialEngineering ceramic Pressure testGB/T13927, API598 Face to FaceGB/T12221, API609 Applications Power plant ash handling system.

A knife gate valve is a component that utilizes a blade to cut through clogging of heavy liquids; whereas a slide gate valve is a component utilizing a slide plate in order to better manipulate or control the flow of dry bulk material. The Knife Gate Valve provides reliable shut-off for both dry and wet line fluids. The bonnet-less valve equipped with a heavy-duty gate to cut though both dry and wet line fluids. The valves find application in paper and pulp, minerals and metals, steel plants, thermal power plants and chemical/ petrochemical industries. The versatile metallic and resilient seats for bidirectional and unidirectional applications. The versatile metallic and resilient seats for bidirectional range is available in wafer, lugged and flanged configurations.
