Comparison Items | Floating Ball Valve | Trunnion Ball Valve |
Ball Structure | The ball has no supporting shaft. Under the action of fluid pressure, the ball can displace to a certain extent and press tightly against the sealing surface at the outlet end to ensure sealing. | The trunnion ball valve on the valve body by the supporting shafts at the upper and lower ends, and the ball cannot have axial displacement. |
Sealing | The floating ball valve seat design: sealing is achieved by the close contact between the ball and the valve seat. The sealing pair is generally a soft seal, such as polytetrafluoroethylene, etc. | The trunnion mounted ball valve have two type: soft seated and metal seated. The soft seatedl is similar to that of the floating ball valve; themetal seated usually adopts a metal to metal sealing. |
Applicable Working Conditions | Generally applicable to medium - low pressure (usually less than or equal to 1.6MPa) and medium - small diameter (usually less than or equal to DN200) pipeline systems. | Applicable to high pressure and large diameter pipeline systems, capable of withstanding high pressures (up to dozens of MPa) and large diameters (up to DN1000 and above). |
Fluid Resistance | The contact between the ball and the valve seat is a line seal. In the fully open state, the fluid resistance is relatively small. | In the fully open state, due to the fixed ball, the fluid can pass through the valve unobstructed, and the fluid resistance is even smaller. |
