Compared with butterfly valve, ball valve seals more tightly and has better resistance to pressure.

We made a special fliter design under the platform of the valve which can not only filter out the blocks in the fluid but prevent the valve from being suffocated by the inner layer of the flexitank due to the sucking force of the pump during discharging. But sometimes we may have to make some flexiable changes on this design according to what kind of liquid you fill.
