BACK TO GLOSSARY

In fluid control systems, flow and pressure are related but distinct. Flow is movement of fluids while pressure is force. A flow control valve controls the volume of fluid flowing through it while a pressure control valve controls the amount of force. In the simplest of scenarios, flow rate is set by changing the size of the orifice of a traditional flow control valve. For more challenging applications, traditional flow control valves do not always work and alternatives are sometimes required. See the Equilibar flow control page for more information about innovative flow control valves.

Li-ion battery manufacturing

Lithium-ion battery manufacturing requires precise vacuum control

Modern devices such as smartphones, laptops, and electric vehicles often use lithium-ion (Li-ion) batteries to store energy. These batteries work by moving lithium ions between two electrodes— one positive and one negative—during charging and recharging cycles to facilitate the storage and release of energy. Battery manufacturing is a complex process.  One of the first steps Read More
