  • Valves 101 Two Types of Ball ValvesCross Company

    A floating design ball valve sandwiches the hollow ball between two or more cupped seats that form a tight seal between the body and the ball at the inlet and outlet ports of the valve body. The ball is rotated (usually 90 degrees) by a shaft that protrudes outside of the valve body and is connected to some form of operator. For this reason most ball valves are referred to as quarter-turn valves.

    Jul 15 2002 · Design engineers typically will use the lowest-rate spring that will allow an adequate range of pressure adjustments (set points) and still retain sensitivity to small changes in pressure. It is possible to reduce the droop with low-rate springs but plants run the risk of making the regulator too sensitive which will create instability.
