A trunnion mounted ball valve
is a type of industrial valve used to control the flow of fluids in pipelines. Unlike floating ball
valves, which rely on the pressure of the fluid to seal the ball against the seat, trunnion mounted
ball valves have additional support mechanisms to handle higher pressures and larger sizes.
- Materials: Carbon Steels, Low Temperature Carbon Steel, Martensitic Steels,
Austenitic Stainless Steel, Duplex Stainless Steels, Super Duplex Stainless Steels, Nickel Alloys,
Nickel Aluminum Bronze, Hastelloy, Inconel, Titanium Alloy & Carbon Steel with Internal
Corrosion Resistant Alloy (CRA) Overlay
- Ball and Stem: The valve consists of a spherical ball with a hollow center
(bore) and a stem attached to one end of the ball. The stem extends through the valve body and is
connected to an actuator or handle for manual or automated operation.
- Trunnion Support: Trunnion mounted ball valves feature two trunnion supports or
shafts, one at the top and one at the bottom of the ball. These trunnions provide additional support
and stability to the ball, allowing it to withstand higher pressures and maintain proper alignment
within the valve body.
- Seat and Sealing Mechanism: The valve body contains inlet and outlet ports, each
equipped with a seat that forms a seal against the ball when the valve is closed. The seats are
typically made of resilient materials such as PTFE (polytetrafluoroethylene) or reinforced metal,
and they provide a tight shut-off to prevent leakage.
- Body Construction: Trunnion mounted ball valves are available in various body
designs, including split-body, top-entry, and welded-body configurations.
- Fire-Safe Design: Many trunnion mounted ball valves are designed to meet
fire-safe standards, such as API 607 or API 6FA.
Trunnion Mounted Ball Valve
Trunnion Valves
Key Features:
- Trunnion Design : Features a
fixed trunnion that supports
the ball, allowing it to rotate freely while minimizing friction and wear.
- Low Torque Operation
: The design requires less torque
to operate compared to floating ball valves, making it easier to control.
-
High Pressure and Temperature
Ratings
: Suitable for high-pressure and high-temperature applications, providing robust performance
in demanding environments.
- Two-Piece or Three-Piece Body
Construction : Available in various designs, enhancing accessibility for
maintenance and servicing.
- Double Block and Bleed (DBB)
Capability : Often designed to provide double isolation and bleed capabilities,
enhancing safety in critical applications.
Application:
- Oil and
Gas: Widely used in upstream and downstream processes for controlling the flow of
crude oil, natural gas, and refined products.
- Chemical Processing:
Ideal for managing corrosive
chemicals and fluids in manufacturing and processing plants.
- Power Generation: Employed
in steam, cooling water, and
other fluid control applications within power plants.
- Water Treatment: Used in
municipal and industrial water
treatment facilities for flow regulation and isolation.
Benefits :
- Enhanced Stability : The
trunnion design provides
stability, reducing the risk of ball displacement and ensuring reliable sealing.
- Low Operating Torque
: Requires less force to operate,
reducing wear on actuators and extending their lifespan.
- Safety Features : Double block
and bleed capabilities
enhance safety in critical applications, minimizing leak risks.
- Durability : Designed to withstand harsh
conditions, offering a
long service life and reliable performance.
