Bevel Gear Cast Steel Gate Valve is a cast steel gate valve product that uses a bevel gear transmission mechanism to achieve valve opening and closing operations through bevel gear reduction transmission. The closing element of the valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The valve can only be fully opened or fully closed, and cannot be used for regulation and throttling. The bevel gear transmission mechanism features large transmission ratio, high torque, and labor-saving operation. It is especially suitable for large-diameter and high-pressure operating conditions, solving the problem of large operating torque in large-diameter gate valves. Bevel Gear Cast Steel Gate Valves are widely used in large pipeline systems in industries such as petroleum, chemical, power, and metallurgy.
