Sigma Valves
Sigma Valves is a specialty valve manufacturer in business since 1968. Innovative-engineered solutions are the inspiration for their product line. Sigma pneumatic, hydraulic, fusible devices, and pressure sensing pilots equip safety and environmentally conscious automation systems in the oilfield, aerospace and pharmaceutical industries worldwide. HistorySigma Enterprises, Inc. began in 1968 as an entrepreneurial vision of founder, Larry Keith Spencer, P.E. Sigmas product line was initiated with pneumatic control valves for oilfield safety applications. Sigma contracted the machine work and assembled, tested and packaged its valves in Mr. Spencers home workshop. In 1971, Sigma grew to its first location in Dallas, Texas and began machining component parts, assembly, and test under one roof. In 1975, Sigma grew to a larger facility to better accommodate its rapidly expanding product line. In 1982, Sigma relocated to its current home in Carrollton, Texas. This 25,000 square foot facility rests on 6 acres and houses all manufacturing and administrative operations. Sigma continues to respond to needs in oilfield, aerospace and pharmaceutical industries with innovative-engineered solutions. A full complement of pneumatic, hydraulic, quick exhaust, fusible devices and pressure sensing pilots that equip safety and environmentally conscious automation systems continue to be in service worldwide. In 1999, the death of founder Larry K. Spencer, P.E. opened yet another chapter for Sigma Valves. His daughter, Lynne Spencer Gerlach was named President and CEO. His son, Derek L. Spencer joined Sigma as sales team coordinator and CIO. The vision of Sigma continues with their commitment to quality, safety and service as their hallmark. |
