Flanged Ball Valves

What are Flanged Ball Valves?

Flanged Ball Valves are 1-piece or 2-piece ball valves that provides effective control of oil and gas operations. Its defining trait is the flanged ends that bolt to oil and gas pipelines.

Flo-Tite’s Flanged Ball Valve is a conventional-design flanged-end floating ball valve. You can easily install or remove this valve from a pipeline or piping system.

This flanged ball valve also features Flo-Tite’s Van Guard stem sealing system. The Van Guard is a state-of-the-art stem sealing system that incorporates three sets of valve stem seals.

  1. A blow-out proof stem shoulder, which has a 45° machined slope, creates the first seal. This sloped design creates more sealing surface than competitors’ valves with typical flat stem shoulders.
  2. An o-ring, which provides a low-torque, flexible seal, creates the second seal. Furthermore, the o-ring eliminates side-loading stress, helping maintain perfect stem alignment.
  3. V-ring packing sets, which expand sideways during compression, create the third seal. These v-ring packing sets use belleville washers to load. This design allows the valve stem sealing system to compensate for wear, pressure or temperature changes.

Flo-Tite’s unique stem sealing system results in long-lasting, dependable ball valves.

Producers can employ these flanged ball valves in on/off, isolation, or high-cycle applications. The Flo-Tite flanged ball valve also includes v-port control and cryogenic options.
