Ceramic Knife Gate Valves are suitable for the conveying system with liquid-solid or gas -solid two-phrase medium , such as ash, mine residue and coal residue in iron and steel plant or ash conveying system of power plant

Ceramic valve disc is mainly used in ceramic gate valve as the valve closing parts,

We custom process ceramic tubes, ceramic elbows,ceramic plates.

FRZ643TC Pneumatic ceramic rotary disc gate valves are designed for pressurized and vacuum systems including dense and dilute phase pneumatic conveying systems, discharge and vent applications in steel plant and coal power. The whole of ceramic sealing faces of the valves are well ground and polished, which is ensure a reliable sealing performance of the valve.

FREE-VALVE’s UPVC back pressure safe relief valve is installed in the line of positive pressure discharge of metering pump,its function is to prevent siphon phenomenon occur. Removing the protective cap on the adjusting screw on site, then rotating and adjusting screw , the required pressure will be got by adjusting pressure gauge in the pipeline. Back pressure will be set within the range of 0-0.6 MPa by adjusting screw .

FREE-VALVE’s Manual operation Square Type Slide Gate Valves are unidirectional knife edge gate valve used on industrial pipeline for on-off operation

FREE-VALVE’s Pneumatic Actuator Ceramic Twin 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 pressure self-sealing and valve disc auto-rotate

FREE-VALVE’s Pneumatic Ceramic Balance 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 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.

FREE-VALVE’s 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 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.
