SmartStep™ Precision Electric Actuators

SmartStep™, by USI, are AC or DC powered precision electric actuators rated for Class 1, Division II, Group A, B, C, and D hazardous areas. They are used for applications requiring 100% modulation and/or open/close operation.

SmartStep™ actuators incorporate non-contact position sensing increases reliability, eliminating wear failure from mechanical switches or contacts.

SmartStep™ is available in four torque outputs, 500, 1200, 2500, or 5000 in-lbs torque. All models include a bright four-line LCD display shows an extensive list of valve states and service advisories, including: valve position, cycle count, back-up power charge statues, current/max temperature values, system faults, and many others.

XOMOX® Cavity-free, Sleeved Plug Valves

XOMOX® sleeved plug valves are are non-lubricated quarter-turn valves that achieve sealing through the use of a compressible sleeve as a sealing member. They provide maintenance-free and cavity-less design benefits, namely no costly lubrication required and no accumulation or contamination of process media. Sleeved plug valves are used for on/off and throttling service in demanding process applications with media temperatures ranging from -20°F to 600°F.

White Paper: Theory, Application, and Sizing of Air Valves in Water and Wastewater System Pipelines

One of the most misunderstood aspects of the water and wastewater industry is the presence of air in a pipeline and its impact on operations. Many operational problems, especially at the time of initial start-up, including damaged equipment, as well as faulty instrumentation readings, are blamed on inadequate thrust blocking, improper pipeline bedding, etc. But in reality, many of these problems are not caused by improper installation of the line, but by failure to de-aerate the line. Properly de-aerating the pipeline with the use of automatic air valves will safeguard it from air-related problems.
