Sealing Makes all the difference.

The key difference beteween a floating ball valve and a trunnion mounted ball valve is how each achieves a line seal. Trunion mounted ball valves are uses a spring mechanism and/or line pressure assistance to drive the upstream seat against the stationary ball. The surface area exposed to the pressure through the relatively small passageway is actually just the back of the seat.

The floating ball valve utilize natural line pressure to press and seal the ball against the downstream seat. The line pressure is exposed to a greater surface area - the entire upstream face of the ball, which is an area equal to the actual pipe size.

What is difference in flange and foot mounted?

Flange-mounted motors are attached to equipment using a flat, circular flange that allows for a secure connection, typically suitable for applications requiring precise alignment and stability. In contrast, foot-mounted motors have a base with feet that can be bolted directly to a surface, making them easier to install and providing a more robust support structure. The choice between the two depends on the specific installation requirements, space constraints, and the type of machinery involved.


Why pressure difference in two gauges located in different heights?

In a pipe line or vessel if vertically placed and two pressure gauges mounted in top and bottom places of the pipe line and the internal pressure will very. Top mounted pressure gauge is lower than the bottom mounted pressure gauge. The Pressure will change due to the height variation's. The Internel fluid height acting additional pressure . so that the pressure difference in two gauges located in different heights.
