Air pressure regulators control pressure in air lines (usually adjustable) to remove fluctuations and maintain consistent pressure for pneumatic devices

Pressure regulators are used to maintain a constant outlet pressure or flow

Air valves allow metered fluid flow in one or both directions.

Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment.

Air compressors are machines that compress air to higher than atmospheric pressures for delivery to pneumatic or robotic tools, industrial equipment, or direct-use applications

Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line

 Pressure vessels are storage tanks that are designed to operate at pressures above 15 psig
