In order to correctly size pressure relief valves (PRVs), a robust understanding of discharge coefficients for vapor, liquid and two-phase flow is crucial A pressure relief valve (PRV) is used to prevent the pressure in a process vessel from exceeding…
The advantages and limitations of three powder-testing techniques are reviewed here Powder testing is deployed to characterize products including pharmaceuticals, foods, metal powders, powder coatings and cement — at every stage of the product lifecycle. The resulting data-support product development…
The V-AN Series of self-regulating centrifugal pumps (photo) features a control system that independently adapts to changing feedrates, meaning that when media flows into a vessel, the liquid level rises until the inflow and outflow of the vessel balance out…
This new Diagnostic Tool application — available on Apple, Android and Windows mobile devices — is a quick and simple way for users of Control Techniques’ drives to solve any error codes that the drive may show. Built within the…
Memosens CPS171D pH electrodes (photo) can be sterilized and are autoclavable for use in bioreactors, fermenters and other hygienic and sterile applications. The CPS171D measures the full pH range of 0–14 and operates in temperatures from 32 to 284°F. The…
The EC2B Series (photo) is a new line of enclosures, control stations and accessories for hazardous-location applications. These standard and custom control stations utilize the company’s EU2B line of hazardous location pushbuttons, pilot lights, selector switches, key selector switches, emergency…
Causti-COR nanofiltration systems are specifically designed to recover and purify caustic for reuse in food, beverage and industrial applications. The systems can recover up to 95% of caustic from solutions used to clean process equipment in industrial applications, says the…
The Gemini 88 Plus dual-rate syringe pump (photo) provides two independent pumping channels linked through hardware and software, combining two individual syringe pumps into one instrument. The syringe pump can infuse simultaneously at different rates, or infuse with one syringe…
This company has expanded the availability of its Uvex HydroShield anti-fog lens coating to include seven new eye-safety offerings, including the clear Flex Seal Goggle (photo), and three lens tints each for the Stealth OTG and Livewire product lines. Uvex…
This company’s new high-pressure (HP) rotary valve (photo) is now available in the U.K. The valve’s design reduces product degradation and also greatly reduced axial air leakage — up to one-third less air leakage than other standard high-pressure valves is…
