The DYNATORQUE valve accessories brand began its legacy in 1973 when Westran Corporation, a producer of truck-trailer landing gear systems, manufactured spur gear boxes to lower the legs of trailer landing gear. In 1974, Westran grew through the acquisition of Indico Inc., which provided the newly formed Valve Components division, a line of quarter-turn worm gear operators as well as position indicators, deckstands, small electric operators, and a short line of cast aluminum handwheels. In an industry where most manual gear manufacturers offered little or no modifications to their offerings, Westran established an expertise in serving a diverse customer base with specially designed products. This helped establish a broader portfolio of solutions, including five additional quarter-turn gearboxes, a short line of bevel gear operators, a complete line of handwheels, and a redesign of the small electric operator line. Westran purchased the ‘MB’ line of large manual quarter-turn gear operators from Raymond Controls to be used in combination with the newly acquired electric line. In 1984, Westran sold its Valve Components division to an investor with close ties to the gas transmission industry, where the product line was renamed to the familiar DYNATORQUE and moved to Sherman Boulevard in Muskegon, Michigan.
Over the next four years, DynaTorque worked to establish customer relationships with Cameron. With the death of the previous owner in 1988, DynaTorque was sold to Hines Corporation, a holding company of several industrial manufacturers. Further development of the Automated Valve Accessories line in collaboration with several customers resulting in the flagship D-Stop partial-stroke test device in 1998 and the D-Lock mechanical valve locking device in 2005. Finally, in 2008, Cameron acquired DynaTorque and expanded the manufacturing plant to become a 56,000-ft2 gear manufacturing facility. Schlumberger then acquired Cameron to further its product portfolio.
