Regulators & Valves

Airtrol pressure regulators and vacuum regulators reduce a variable supply to a steady output setting. Pressure applications include Oxygen concentrators, ventilators, HVAC systems and custom machinery. Vacuum applications include medical equipment, pick ‘n place, laboratory instruments and process control. Several output ranges up to 90 Psi (pressure) and 30″Hg (vacuum). Various adjustment styles and factory preset models. Available mounting styles are panel, base or manifold. Special options include a brass adjustment shaft and Oxygen clean parts.

Pressure regulators consist of three primary elements: a pressure-reducing element, a pressure-sensing element (e.g., diaphragm or piston), and a reference force element. In operation, the reference force element prompts the reducing element to open. The air flowing into the valve presses against the sensing element, which then prompts the valve to close when pressure levels reach a set standard.

When used within pneumatic systems, these devices result in the following:

  • Better system operator safety
  • Lower system operating costs
  • Greater consistency in air flows and pressures
