The cast iron square gate adopts the top mounted structure, which reduces the connecting bolts of the valve body itself under the condition of high pressure and large diameter, enhances the reliability of the valve and overcomes the influence of the system weight on the normal operation of the valve.
Cast iron square gate is widely used in coal chemical industry, petrochemical industry, rubber, papermaking, pharmaceutical and other pipelines as the medium of diversion and confluence or flow switching device.
