A floating ball valve offers a straightforward way to isolate a process line: turn the handle through a quarter turn to open or close the passage. Its compact construction makes it a familiar choice for plant piping, utility systems and equipment connections.
Farpro supplies cast steel and stainless steel floating ball valves, including the Q41F and Q41Ni series shown below. Browse the models to compare body materials, seats and dimensions for your installation.
How a Floating Ball Valve Seals
The stem turns the ball, while the seats hold it within the body. There are no trunnion supports fixing the ball along its rotational axis. Under line pressure, the ball moves slightly toward the downstream seat to form the shut-off seal.
The simple quarter-turn mechanism works well for local isolation and can also be paired with an actuator. For a replacement, check the connection and installation length as well as the valve size; two valves with the same nominal diameter do not necessarily fit the same space. Kita valve replacement guide explains which installation dimensions to record.

Floating or Trunnion-Mounted?
The difference is how the ball is supported. In a floating design, line pressure moves the ball toward its seat. A trunnion-mounted valve supports the ball at its rotational axis and uses the seats to maintain sealing contact.
As size and differential pressure increase, the way those loads reach the seats affects operating torque. That makes ball support an important part of selection, alongside the bore, seat material and operating conditions.
Seat material is a separate choice: floating and trunnion-mounted designs can both use soft or metal seats. The support arrangement alone does not tell you the temperature limit or sealing performance of a particular valve.
For a closer look at the range, compare the cast steel Q41F with the stainless steel and metal-seat models listed above.
Finding the Right Replacement
If you have a valve to replace, a clear photograph and the existing model often make a useful starting point. We can help you work through the differences between the old valve and the available options before preparing a quotation.
For a new line, send us the valve specification you are working to. You do not need to settle every product detail before getting in touch.
