Our mechanical pressure regulator options include those that control an application’s pressure downstream (pressure reducing) and those that are regulating upstream pressure (back pressure). Our general purpose line is a pressure-reducing option available for sale online.

Frequently Asked Questions

  • Mechanical pressure regulators function by limiting the flow of a liquid or gas upon reaching a specific pressure threshold. When the spring’s or dome pressure’s force displaces the seal from the valve seat, fluid can pass from the regulator’s inlet to its outlet. As the outlet pressure increases, the sensing element’s force counters the spring’s force, resulting in the valve’s closure.

  • A few precautionary measures we recommend include (but are not limited to)

    • Protect your eyes/hands: Wear safety glasses and protective gloves, especially when connecting and disconnecting regulators and lines.
    • Avoid flammable materials: Don’t use oils, greases, or creams.
    • Avoid sparks/open flames: This creates a much higher risk of explosion.
    • Don’t wear jewelry: Watches, rings, or bracelets can freeze to exposed skin if splashed by an ultracold gas.

    *We recommend reading the manufacturer’s manual for further safety instructions*

  • Consider the required downstream flow rate. Choosing a regulator with insufficient capacity can lead to pressure drops and affect equipment performance.

  • Pressure fluctuations upstream can affect outlet pressure stability. Consider regulators with good pressure drop compensation for applications with variable inlet pressure.
