overview of valve & pump & hydraulics & pneumatics (3594-vp)

— valves are devices that control flow of liquids or gases. valves can also be hydraulic valves, pneumatic valves or electric valves as well as having an various types including check valves, butterfly valves, globe valves, gate valves and ball valves. depending on the liquids and gases that a valve may come in contact with, it may be ideal to use corrosion-resistant plastics such as pvc, cpvc, polypropylene, ptfe and other engineering plastic materials. these materials are ideal for many industries including agriculture, defense, chemical processing, power generation and petrochemical. pumps are essential mechanisms that are utilized in many industrial manufacturing processes. pumps are devices used to raise, compress or transfer fluids or gases. pumps can be hydraulic pumps, pneumatic pumps or electric pumps and include a large variety of types such as centrifugal pumps, diaphragm pumps and vacuum pumps. pump manufacturers also mainly fabricate industrial pumps from metallic materials, but use thermoplastic and elastomeric materials such as teflon and polypropylene as well.
