Control solenoid valves are used to flow air or gas in pneumatic systems where versatility and reliability cannot be compromised for fast response times or low power operation. Available as a 2-way or 3-way design in various mounting styles, these compact valves are easily manifold mounted or soft tube connected making them the perfect solution for applications where many valves must be designed into the smallest space possible. In addition to conventional solenoid valves, we offer magnetically-latching solenoid valves that consume far less power, which helps conserve energy in battery-powered applications. We also offer quiet solenoid valves, which feature technology to significantly reduce the actuation noise you typically hear when a solenoid valve is energized. With a sound profile of ≤ 30 dB, it is ideal for patient simulators and a variety of bedside pneumatic applications where actuation sound would otherwise interfere with patient comfort.
The Difference Between Calibrated Orifices and Holes
Engineers tasked with managing fluid flow talk about both holes and calibrated orifices, but they are two distinct entities. A hole can beany opening, but a calibrated orifice is specially designed to precisely control fluid flow. Consequently, its diameter, length, and geometry are critical to its intended operation. With the right design, an orifice can provide the desired control over fluid flow rates and pressure spikes.
Key Considerations for Selecting a Medical Pump
Newcomers to medical device design may think that pressure and flow rate are sufficient parameters to consider when it comes to selecting a pump. While this may be the case in some industrial applications, medical device requirements are a bit more demanding. A thorough review of the selection criteria for a medical pump is required to ensure the correct pump is chosen for every application.
Adapting Fluid Control Components for Hydrogen Applications
Although aviation is a relatively small contributor to global greenhouse emissions, it is also one of the fastest-growing. The major airline companies are aware that the goal of minimizing their carbon footprint is tied to the eventual elimination of the use of fossil fuels. Many of the industry’s major airlines have publicly announced plans to completely phase out carbon-based jet fuels from their operations in favor of a clean-burning alternative—hydrogen. Transitioning from fossil fuels to hydrogen will require modifications to or replacement of current technologies that control liquid fuel. As engineers assess the impact of these significant modifications, it is important that they address the unique challenges associated with controlling pneumatics in general and hydrogen in particular. This article addresses those challenges associated with the design of components used to control fuel between the storage tank and the combustion chamber of an aircraft, such as flow restrictors, valves, and filters.
