<p>A gate valve, whose valve seat uses an inlayed corrosion-resistant and wear-resistant lining, separates the medium flowing through the valve from the valve seat, thus the medium flowing through the valve only contacts the lining and the gate plate. The gate valve can be used as the switch valve in high corrosion and high wear conditions in the mining, power, chemistry, pipe making, food and environmental protection industries.</p> |
