The Global valve is named because the shape of the valve body, which is similar to a spherical. The most important feature of global valve is effective throttling.
Globe valve is different from ball valve, used for closed, switch often and used as throttling Valve to control flow through. The ball valve is also better at regulating and stopping the fluid than the gate valve. The most important function is to avoid fluid resistance and pressure drop, which can reduce the friction and loss to the valve. Flow control, pressure drop and load range must be considered in the design of the valve, different forms depending on the occasion, pressure, material, etc.
