In 1948, Detroit Regulator Co. was awarded a patent for its innovative Straight-Thru-Flow (STF) regulator design. Also known as the Maxitrol (Maximum Control), the STF design allows gas to flow straight through the regulator without changing directions.  Maxitrol's design team continues to create and produce inventive products including the 325 series regulators for use with 2 psi and 5 psi piping systems, the Selectra electronic gas flame modulation systems for direct and indirect fired heaters and, in 2003, the DFM series temperature controls for use with direct gas-fired modulating air heaters.  Throughout the years Maxitrol Company has undergone many changes and faced many challenges, but through the work of talented and dedicated employees, it continues to develop innovative technology for the natural gas industry.  Loy Instrument has maintained a strong presence with Maxitrol both through inventory and support for our customers. Make it a point to take advantage of local distribution for your gas control needs with Loy Instrument.
