Characteristics of Floating Ball Trunnion Valve

Our cast floating ball valves are designed to provide tight and efficient sealing in various industrial applications. Made by casting, these valves are economical and available in a variety of sizes and materials, including stainless steel and carbon steel.

Common Applications of Trunnion Ball Valves

These valves are ideal for a wide range of applications, including drinking water systems, wastewater treatment, and in the petrochemical industry. They are also widely used in heating, ventilation and air conditioning (HVAC) systems and in the oil and gas industry for low to medium pressure applications.

1. Floating Ball Design:

   • The ball is not fixed and floats within the valve body, allowing fluid pressure to push it against the seat to achieve an effective seal.
   • This design ensures a tight seal, even at low pressures.

2. Cast Construction:

   • Manufactured by casting, allowing mass production and availability in a wide variety of sizes.
   • Common materials include stainless steel, carbon steel, and other corrosion-resistant materials.

3. Efficient Seals:

   • Equipped with high quality seals such as PTFE (polytetrafluoroethylene) and elastomers, which ensure long life and reliable sealing.
   • Seals can be replaceable, making maintenance easier.

4. Simple Operation:

   • Generally operated by a manual lever actuator, but also available with pneumatic or electric actuators.
   • Full or reduced bore design to accommodate different flow requirements.

5. Connection Variability:

   • Available with various types of connections such as threaded, flanged or welded.
   • Flexibility to be installed in different systems and pipes.
