Floating Ball VS Trunnion Ball

 

Floating Ball Design

The design of TEKO DBB ball valves is based on the “floating ball” principle which allows the ball to turn freely between the ball seals.

A positive seal is attained by fluid pressure acting on the upstream surface of the ball and producing a constant uniform contact between the downstream ball seal and the ball. The ball is operated by a sealed spindle with a projecting square end to which the control handle or optional actuator is attached. Ball valves are intended to be used as on/off flow control devices and are not to be used to throttle fluid flow. The valves should always be either fully open or fully closed.

 

Trunnion Ball Design

Trunnion ball valve have a mechanical means of anchoring the ball at the top and the bottom, this design is the standard design applied on larger and higher pressure valves.

Sealing is achieved by spring loaded piston type seats which shut off flow when line pressure acts on the upstream seat. Automatic relief of cavity overpressure is assured due to the trunnion design in case of self-relieving seats. The ball is operated by a sealed spindle to which the operator is attached. Ball valves are intended to be used as on/off flow control devices and are not to be used to throttle fluid flow. The valves should always be either fully open or closed.
