Industrial heritage of TruTorq and production facilities in Rovato

Italian engineering company TruTorq specializes in designing and fabricating quarter-turn valve automation for process industries worldwide. Since 1991 the primary manufacturing base of TruTorq has operated in Rovato within the Brescia industrial region.

The manufacturing facility features precision CNC machining centers, automated testing bays, and hydrostatic evaluation loops.

Engineering teams at TruTorq advance pneumatic actuator design standards through patented internal spring layouts and low-friction polymer guide bearings.

Products engineered at the Italian facility serve demanding chemical plants, energy generation stations, and offshore marine networks across international markets with proven operational endurance.

Mechanical advantages of C-Type rack and pinion actuators

Trutorq C-Type pneumatic actuators deliver quarter-turn rotational force to operate ball, plug, and butterfly valves throughout industrial processing networks.

The core engineering hallmark is the placement of return springs within hollow piston racks, maintaining identical external dimensions for single-acting spring return and double-acting configurations.

Integrating encapsulated polyoxymethylene POM guide pads eliminates metal-to-metal contact against internal cylinder walls, minimizing friction coefficients and preventing mechanical seizing.

Standard external stroke limit stop bolts permit precise field tuning of valve open position angles while the actuator remains directly installed in the pipeline system.

Compact S-Type units and modular E-Type actuators with body adapter

For compact valve installations Trutorq engineers developed the lightweight S-Type series featuring anodized aluminum bodies and polyester-coated end closures.

These compact units generate torques reaching 101 Nm at 6 bar working pressure, ensuring smooth rotation on modular water treatment skids, HVAC circuits, and chemical metering piping.

The E-Type actuator family incorporates an integrated body mounting adapter that aligns directly with various pipeline valve flanges without requiring external brackets.

Dual external travel adjustments positioned completely outside the pressurized internal chamber enable maintenance technicians to calibrate travel limits safely during active plant operation.

Corrosion resistance of TSS series AISI 316 stainless steel actuators

Trutorq TSS pneumatic actuators are engineered specifically for operational environments exposed to aggressive marine salt spray, corrosive acids, and harsh chemical vapors.

Entire body components and internal drive gears are machined directly from solid AISI 316 stainless steel billets, eliminating porosity and void defects inherent to molded metals.

The driveshaft features an integral double-adjustment travel cam machined as a single monolithic component to eliminate rotational backlash and joint wear.

Operating reliably between 2 and 10 bar supply pressures and across temperatures from minus 30 to plus 100 degrees Celsius, TSS units provide dependable valve control on offshore platforms.

SY heavy duty scotch yoke actuators for pipeline flow control

To automate heavy large-bore quarter-turn valves on main transmission lines, Trutorq manufactures SY series heavy-duty pneumatic actuators featuring a symmetrical scotch yoke drive mechanism.

The yoke linkage generates maximum mechanical torque at break-away and shut-off positions, matching the resistance curve of high-pressure pipeline valves.

Constructed from welded heavy-gauge structural steel, the SY body receives high-durability epoxy powder coating in protective RAL 3020 finish.

Output torque reaches 300000 Nm in double-acting models and 107520 Nm in spring-return units, ensuring immediate pipeline isolation during emergency shutdowns even when pilot pressure drops rapidly.

Hydraulic HY actuators and ACL linear pneumatic cylinders

The heavy automation line includes Trutorq HY hydraulic scotch yoke actuators engineered for filtered hydraulic fluid at working pressures reaching 100 bar.

These units generate output torque up to 300000 Nm and feature rugged mechanical travel stops that provide precise angular calibration of plus or minus five degrees at travel ends.

For linear slurry knife gate valves, Trutorq provides ACL aluminium pneumatic cylinders with bore diameters ranging from 100 mm up to 320 mm.

The piston integrates a permanent magnet ring for non-contact magnetic position detection, while standard NAMUR pneumatic connection ports enable direct solenoid valve assembly without separate piping.
