Cast Steel Low Pressure Gate Valve is a gate valve product specifically designed for low-pressure operating conditions. The valve body is manufactured from high-quality cast steel material, providing good mechanical properties and cost-effectiveness. 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. Cast Steel Low Pressure Gate Valves feature simple structure, good sealing performance, and light operation. They are suitable for low-pressure and normal-temperature operating environments and are widely used in low-pressure pipeline systems in industries such as water treatment, urban water supply and drainage, and HVAC.
