  • 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 be any opening, but a calibrated orifice is specially designed to precisely control fluid flow. Consequently, its diameter, length, and geometry are critical
  • Fine Powder Design - Flow Rate Control (.pdf)
    Engineers must often control the mass flow rate from a handling system by using a volumetric feed device. This poses several problems. Accurate control requires three conditions: consistent bulk density, geometries that are not flow rate limited, and orifice sizes greater than cohesive hang-up
  • An Engineer's Guide to Selecting a Flow Restrictor
    A flow restrictor is any device that restricts or limits the flow of a fluid --generally a liquid or a gas. Such devices may also be referred to as flow limiters. Calibrated orifices are one example of flow restrictors. They are used in systems we encounter daily. For example, they control how fast
  • Traditional solenoid valves are simple to install but may not be the right solution for long term reliability or high flow applications
    an internal spool arrangement that has a number of small orifices to control flow. These valves can suffer both reduced flow due to the spool obstructing the fluid's flow path and erratic operation when the orifices clog. Electrically actuated ball valves have replaced solenoid valves in many
  • Control Valve Solutions for Critical Power Applications
    The valve was designed to supply 750#/hour with one set of jets in service, and 1500#/hour with two sets of jets in service. The original sizing of the orifice was ¼", however evaluation of the flow characteristics showed that the flow with two jets in service was reaching >90% of the valve opening
  • Rheological Instrumentation for the Characterization of Polymers
    Traditional tests for polymers focus on the. amount (mass) of material passing through a. known diameter orifice in a given time frame,. usually 10 min. This type of test, known as fluidity. index or melt index (MI), provides a single. point measurement of the flowability of a material
  • Industry Solutions For The Most Common Solenoid Valve Challenges
    the solenoid valve, thus, allowing the orifice - from which water flows - to open and activate a sprinkler system. This helps keep the fire under control and prevent spreading to other parts of the building. Meeting SIL Standards. Solenoid valves must be of good quality and meet Safety Integrity Level (SIL
