Description

Air pressure regulators control the pressure in air lines used by pneumatic tools and machines. To provide consistent pressures, they remove fluctuations in the air supply and are adjustable. The reduction in pressure is the key characteristic of pressure regulators; outlet pressure is always less than the inlet pressure. The applications for air pressure regulators vary considerably. Air pressure regulators are found in many common applications such as in gas grills, propane pressure control, and in medical/dental equipment to regulate oxygen and anesthesia gases.

Three functional elements comprise: a pressure regulator. A pressure reducing element, a sensing element, and a reference force element. When operating, the force element produces a force that opens the reducing element. Pressure introduced into the inlet port then flows through the valve and presses against the sensing element. The regulated pressure acts on the sensing element to produce a force opposing the spring force and closes the valve.
