                Z643TC pneumatic single-gate ceramic gate valve/Z644TC pneumatic double-gate ceramic gate valve is used for feeding valve of silo pump in dry ash system of power plant. It can be used for high-hardness granular media. It can also be used for opening and closing of worn dry dust and water vapor in mines, papermaking and chemical industry. Nominal pressure 1.0MPa, suitable for temperature less than 150 degrees Celsius.


                The sealing surface is made of structural ceramics, which has high chemical stability and hardness. Its service life is 510 times longer than that of ordinary material valve. Therefore, the valve has a very high wear resistance, corrosion resistance, erosion resistance, and good thermal insulation, thermal expansion is small, so the valve for users to bring very high economic benefits.


                The valve material is completely circulated without blockage, and there is a compressed air automatic plugging device.


                The valve is made of high-grade toughened structure ceramic seal, with high mechanical strength, good abrasion resistance and long service life. Compact structure can be installed at any angle.

                Structural characteristics of ceramic gate valves


                1, with the cylinder as the driving device, it directly pushes up and down the movement of the gate, and the speed of opening and closing is fast.


                2. Double gate is connected by floating connection to form a reliable one way seal under the action of medium pressure. At the same time, the floating connection can make the gate rotate and rise because of the axis discenter when opening and closing, so that the friction lines between the gate and the valve seat are evenly distributed, and there will be no line wear, thus greatly improving the service life.


                3, the valve body and the gate seal face lining wear resistant ceramics, the wear-resisting performance is superior.


                4, small volume, easy to transport, installation and maintenance.


                Working principle of ceramic gate valve


                When the cylinder drives the gate downward through the stem, the gate coincides with the sealing surface of the valve body, cutting off the passage, that is, closing; otherwise, opening.


                Installation, use and maintenance of ceramic gate valves


                1, before installation, the valve should be cleaned and removed from the defects during transportation.


                2. Check the labels and nameplates on the valves to meet the requirements.


                3, the valve can be installed at any angle of the pipeline.


                4. The valve should be fully open or closed when it is in operation. It can not be used as throttle valve. Otherwise, the sealing surface will be washed out and lead to accelerated wear and tear.


                5, if stored for a long time, they should be kept in a dry and ventilated room and checked regularly to prevent rusting.


                6, avoid bumping during transportation.
