SmartStep™ Precision Electric Actuators

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

Sizing of Air Valves

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.

Installation and Startup for the Quest-tec Magne-Trac Magnetic Level Gauge

The Quest-tec Solutions Magne-Trac utilizes a non-magnetic pipe chamber mounted directly to a vessel. The process connections from the chamber to the vessel act as an inlet and outlet that allow the liquid level in the pipe chamber to match the level in the process vessel. Inside the chamber, a custom designed float rises and falls with the level of the liquid in the chamber. A 360ยบ magnet array within the float projects a magnetic field through the pipe chamber to an externally mounted indicator to provide a visual read out of the liquid level within the vessel.

The Magne-Trac™ level indicator is easy to install, low maintenance, and easy to view. Accessories include point level switches and transmitters to provide integration into plant control systems.

The Quest-tec Solutions Magne-Trac Plus combines the Magne-Trac magnetic level gage with the Bridle-Trac by pass chamber. It may be used with our VAR Partner E&H GWR or customer specified radar for redundant level measurement. The Magne-Trac Plus is recommended in applications that require both visual and electronic level viewing.

Flowrox Valve Solutions for Demanding Shut-off and Control Applications

Flowrox Valves

Heavy Duty Pinch Valves


Flowrox heavy duty pinch valves are “The pinch valves”. They are made to last and are ideal where shut-off and control applications involve abrasive or corrosive slurries, powders or coarse substances.

General Line Pinch Valves


Flowrox general line pinch valves are robust and cost- effective valves with simple, single-sided closing mechanism. PVG valves have a strong valve body and opening tags in the sleeve as standard. PVEG valves have a corrosion resistant and light-weight plastic body. They are ideal for low cycle applications involving abrasion, corrosion and aggressive slurries. Through the reliability and structure, they offer substantial savings based on improved performance, long service lifetime and low total cost of ownership.

Slurry Knife Gate Valves


Flowrox Heavy Duty Slurry Knife Gate Valves isolate flow, even in the most demanding process conditions. The complete valve is built around an ease-of-maintenance concept. The designs of Flowrox Slurry Knife Gate Valves are based on the years of experience Flowrox has gained, providing reliable solutions for abrasive and corrosive process applications.
