Frequently Asked Question

Do you have any question?

Top entry ball valves are valves that assembled its ball from top side part. It just like a globe valve that has body and bonnet except the trim part utilize a ball type. It comprises a one single body. Usually top entry ball valves are made from casting metal.

Ball valves are perhaps the easiest valve to see if they are open or closed. If the handle on top is parallel to the valve, it's open. Likewise, if the handle is perpendicular to the top, the valve is closed.

That's a little premature for failure but being they are mechanical there is no reason to expect them to last longer than any other mechanical valve. They all have a failure rate.
