Hard sealed pneumatic forged steel ball valve 600LB 4-inch
The ball valve is a valve that uses a ball with a circular through hole as the opening and closing part, and the ball rotates with the valve stem to realize the opening and closing action. Perfectly equal valve body chambers provide a low-resistance, straight-through flow path for the medium. The ball valve not only has simple structure and good sealing performance, but also has small size, light weight, less material consumption, small installation size, and small driving torque within a certain nominal diameter, easy operation, easy to achieve fast opening and closing, easy to operate and maintain.
Globe valve is a commonly used shut-off valve, is a forced sealing valve, when closed, pressure must be applied to the disc, so that there is no leakage between the two sealing surfaces, but also to overcome the pressure of the medium, the sealing force required is much greater than the gate valve. When the disc opening height is 25% of the nominal diameter, the flow rate has reached its maximum, indicating that the valve has reached the fully open position.
