Application & Function:


TKEO Cast Trunnion Ball Valve have been designed for severe oil and gas applications, including production, transportation and distribution.

TEKO Cast Trunnion Ball Valve designed the Side-Entry Trunnion-Mounted Ball Valves to assure bi-directional sealing of the valve with two independent floating seats. The design of these seats minimizes the torque required to operate the valve without losing the sealing power. This power is assured by zero differential pressure to the valve’s maximum rated pressure. In addition, these repairable valves are manufactured to seal off both seats at the same time and to allow bleeding of the entrapped cavity pressure (DBB) with the ball in the closed position. The DBB feature allows for verifying that the seats are properly sealing.

 

Design Description:


- Structure : 2 pieces or 3 pieces body
- High shut-off sealing mechanism and low torque operation
- Block and bleed function
- Self-cavity pressure relief
- Fire safe design
- Blow out proof stem construction
- Anti-static design
- Locking device (for lever handle operation)
- ISO 5211 actuator mounting
- Emergency grease injection (option)
- PN design can be available

 

 

What is Trunnion Ball design

 

As described above, there comes a point where owing to the high value of the loading forces on the ball it becomes no longer possible for the seats to support the ball and an alternative design is required.

 

The trunnion mounted ball design in effect addresses this problem where in effect the shaft, ball, and trunnion act as single assembly that supports the ball instead of the seats and the seats become “floating” in a kind of reversal of the “floating ball” design. Similarly, trunnion mounted ball design is also capable of bi-directional sealing.

 

An advantage of trunnion ball design over floating ball is the lower operating torque of the ball. This is particularly advantageous when the ball valve is actuated because it reduces the size of the actuator and hence the overall costs of the valve actuation package. Obviously this difference becomes important when the pressure class and valve increases.
