The G3 and 580 platforms can support 128 Series 501 solenoid valves and 80 Series 502 and 503 valves. Flexible process control architecture helps to optimize control cabinets for the number of valves required for a specific application. Midsection blocks with valve drivers and auxiliary connectors allow users to select only the capacity and functionality required for a particular design. The electronic platforms support a range of electronic protocols including ethernet/industrial protocol (IP) device level ring (DLR), PROFIBUS decentralized peripherals (DP), and valve subbus for distribution.
Bulk Bag Discharger Contains Trace Amounts of Dust
The BFC bulk bag discharger features an enclosure to contain errant dust and prevent it from escaping through the seams or fabric of unlined bulk bags. Polymer panels enclose the sides, rear, and top of the frame, while a port on the rear panel allows venting of the enclosure to a centralized dust-collection system. The enclosure works with the discharger’s dust-tight bag spout interface and expands the ability of the discharger to contain dust from all areas of the bag. A manual clamp ring atop a pneumatically actuated telescoping tube enables quick, dust-tight connection between the bag spout and hopper. The bag automatically elongates as it empties to promote flow and evacuation. A dust-tight seal between the bag spout and clamp ring allows discharge from the bag without dusting. A pneumatically actuated flow-control valve cinches the bag spout concentrically with no leakage of material, allowing the bag spout to be gradually opened, and partially empty bags to be retied.
Hydronic Ball-Valve Hose Threads Offer Quick-Connect Technology for Copper Systems

The system includes predictive monitoring capabilities, and it can be integrated into a digital control system or supervisory control and data acquisition (SCADA) system through digital protocols.
Warning Systems Safeguard Personnel Near Loading Docks
Two motion-light warning systems mitigate the various dangers faced by personnel working on loading docks. Inside the dock area, Pedestrian-Vu uses motion-sensing technology to trigger a bright blue light that projects onto a dock leveler. The blue light flickers as an audible alarm alerts unsuspecting dock workers that they have entered an unsecured trailer, while an external light system simultaneously changes to red, warning truck drivers that there is activity inside the trailer. Outside the dock area, from a fixed location above the dock door, the Approach-Vu sensor detects motion of trucks backing into a dock position. A visual and audible alarm located on the vehicle restraint system, which helps prevent vertical and horizontal trailer movement, alerts dock workers and nearby pedestrians of impending danger.
Gas Detector Eases Calibration Tasks
