Critical Aspects of a Valve's Internal Design Out of sight often means out of mind, but when valves are concerned, that which is out of sight should be top of mind—at least during valve selection. This paper will discuss key internal design characteristics a valve should have in order to meet high efficiency, critical control demands common in pharmaceutical, medical, or analytical applications. These design features include the valve's flow path, dead space, flushability, and internal volume. Flow Path For fluids susceptible to hemolysis or

Boyle's Law Boyle’s Law is a basic law in chemistry describing the behavior of a gas held at a constant temperature. The law, discovered by Robert A. Boyle in 1662, states that at a fixed temperature, the volume of gas is inversely proportional to the pressure exerted by the gas. In other words, when a gas is pumped into an enclosed space, it will shrink to fit into that space, but the pressure that gas puts on the container will increase. Perhaps a more straightforward way is to say Boyle's law is the relationship between pressure and volume. Mathematically, Boyle’s law can be written as pV=k, where p is the pressure of the gas, V is the volume of the gas, and k is a constant. An example of Boyle’s law in action can be seen in a balloon. Air is blown into the balloon; the pressure of that air pushes on the rubber, making the balloon expand. If one end of the balloon is squeezed, making the volume smaller,
