    , multiply the flow rate by. 3. In the case of a liquid, water is used as a representative; in the case. of other liquids, multiply the flow rate by. 4. When the viscosity is high, however, contact us for the specific coef-ficient of viscosity. CAUTION -Precautions on use of needle valves-. Needle valves

    tubing. The metering needle in these valves accurately reduces the split flow down to as low as 2 ul/min. Upchurch Scientific, 619 W. Oak St., Oak Harbor, WA 98277. High-flow check valves Clear one-way check valves of unique design offer unimpeded fluid flow, low opening pressure, and no backflow
  • Coker Valve Monitoring in a Refinery
    CAS DataLoggers recently provided the data acquisition and control solution for a large manufacturer of valve systems for use in many different industries. The company produced ball, needle, choke, control, gate, and other types of valve systems of many different diameters. Coker Valve Monitoring
  • Pressure Gauge Accessories: Insurance for Productivity
    accessories can help reduce the risk of failure, extend the life of the gauge, and maximize equipment performance. A needle valve can isolate the pressure gauge from the measured fluid or can help dampen pressure pulsation. A mini-siphon protects gauges from harmful steam, vapors and liquids
  • Advances in Back Pressure Regulator Design Enable Supercritical CO2 Research
    at this scale. The formation of. solid CO2 associated with the adiabatic pressure. Needle. reduction across the regulator can result in significant. Dome-loaded. Back Pressure Regulator. Valve. blockages in conventional needle valve systems at. low Cv values and high pressures. This can result in. Mann’s
  • Three Process Conditions That Affect Accuracy And Performance Of Pressure Gauges (.pdf)
    and they. can be a piston-type snubber, a sintered metal snubber, or a threaded in-flow restrictor in the. socket of the gauge. A needle valve installed upstream of the gauge that is “pinched down” or. slightly opened, is another common practice to address pulsation. It is not recommended to rely

    delivery, milliliter delivery, and high-force delivery. Swabbable luer valves were developed as substitutes for needle ports in IV applications. The needleless valves allow multiple usage, require no cap, and have good flow and low priming volume. Valve stems and bodies will mate securely. MPMN
  • Medical Device Link .
    . Needle-free valves. Needle-free valves reduce the need for caps, cannulae, and add-on components, while protecting healthcare providers. The SmartSite valves have a high flow rate and low priming volume in addition to a straight-through fluid path. Characterized by a latex- and DEHP-free design, the units
