Abrasion-Resistant Ball Valve Boasts Long Lifespan
The QuadroSphere ball valve features a unique abrasion-resistant ball design with four recessed surfaces that provide additional flow paths through the valve to allow for self-flushing. This prevents clogging due to scale and solids buildup and also protects the seats from damage. A ground and polished hard chrome plated stainless steel ball substantially reduces ball-to-seat surface contact, creating less resistance during cycles and lowering the operating torque. The abrasion-resistant ball design improves the lifespan of the ball and seats. The valve is available in sizes 2 NPS to 24 NPS and in ASME Classes 150–2500. It can be supplied with a pneumatic, electric, gear, or lever actuation, and additional options include standard single-piston effect seating or double-piston effect seating. In the event of damage to the seat insert or stem seals, sealant can be injected to temporarily seal the valve until repairs can be made. The valve is manufactured under a certified ISO 9001 quality system and meets API, ASME/ANSI, BS, ISO, MSS, and NACE standards. It is suitable for a variety of industries, including chemical, refining, oil and gas, power, and pulp and paper.
Mobile Application Accesses Remote Server for Simulation
Engineers in the field can use COMSOL Multiphysics simulation software without the need to transport heavy and cumbersome computers, as the software can now be accessed on phones, tablets, and Chromebooks. The COMSOL Client for Android app is now available in the Google Play store and enables users to run COMSOL Multiphysics applications from mobile devices. Android users will have the latest version of the simulation software each time they open the app. Simulation specialists can use the Application Builder to create custom-made applications based on their multiphysics models, and then connect to the COMSOL Server (via the COMSOL Client) to deploy industry-specific analysis tools in a streamlined format that is easy to scale. Administrators will continue to have full control over who can access and run the apps via the COMSOL Server.
Process Models Improve Data Analytics
The SIMCA 16 software for multivariate data analytics saves time with its modeling and data preprocessing capabilities. The updated version focuses on complete data analysis, from data organization to data-driven decision-making, supported by multivariate models for single and multiblock analysis. The software makes model data easier to interpret for better process control, and mines data to help optimize product quality, resource use, and cost analysis. The improved graphical interface uses its context-based ribbons and panes so that users spend less time looking for functions. The new data analytics system includes a wizard that adapts to users’ modeling objectives (rather than focusing on which algorithm to use) and makes the initial steps of creating each model easier as it guides them through the setup. The advanced data merging functionality saves time by eliminating the need to manually combine and align data in Excel. A Python plugin enables users to create a file-reader plugin that can read files as they are imported. This allows operators to translate data from instruments with a non-standard export format or where data is not configured correctly for the software, saving them time and effort with preprocessing and importing data.

Low-Level Chlorine Analyzer Operates Autonomously
The Orion 7070iX TRO analyzer measures low chlorine concentrations in wastewater applications. It employs the U.S. Environmental Protection Agency (EPA)-approved iodometric electrode technology, which does not experience turbidity or color interferences. It offers high sensitivity for low-level chlorine measurements down to 1 ppb and up to 15 ppm, with a resolution of 1 ppb. The analyzer can operate autonomously for long periods of time with minimal instrument drift (<5% over more than 180 days without calibration), eliminating the need for routine maintenance. A self-cleaning feature prevents chemical and biological fouling of the measurement cell and sensor, minimizing downtime and enabling continuous testing. It can operate in an intermittent on-off mode based on sample flow — once the flow starts, the unit’s pumps turn on, then they shut down as soon as the flow stops. The analyzer also provides real-time monitoring of total residual oxidant (TRO) fluctuations, alerting users within 120 sec of any change to prompt timely corrective actions.

Machine Assessment Services Mitigate Risk
Machine risk assessment services help factory owners, asset owners, and employers mitigate risk within an industrial workplace and provide a safer work environment. Industrial machines are evolving and becoming more automated. Many factories contain equipment purchased decades ago alongside more modern, fully automated robotic systems. Some older equipment can fail to meet today’s safety requirements, creating a substantial risk to users. These failures occur due to gaps in general maintenance, failure to install or replace guards, easily exploitable manual overrides, and other contributing factors. Onsite risk assessments can be conducted across industries and a wide range of machine types, for a single machine or an entire factory. The services are based on Occupational Safety and Health Administration (OSHA), American National Standards Institute (ANSI) B11, International Organization for Standardization (ISO) 12100, National Fire Protection Association (NFPA), Robotic Industries Association (RIA), and other applicable standards.
