We are pleased to announce that Equilibar now offers direct replacements for select models of Mity Mite back pressure regulators.
Mity Mite regulators were first manufactured by Grove Valve and Regulator Company in the 1960s and soon became the standard for many specialty applications. The Pressure Reducing Mity Mite regulators were quite common in experimental rocketry due to the lightweight construction of the aluminum model while the Back Pressure Regulating Mity Mites became popular for applications in the oil and gas industry because of their materials of construction and low flow capabilities.
Over the years, the Mity Mite product line was sold multiple times. In 2015, the most recent owner announced discontinuation of support for Mity Mite, leaving long-standing customers in a bind.
Many of Equilibar’s customers have successfully used Mity Mite regulators for years and need a reliable source for future orders. To better serve these customers and the industry, Equilibar now offers direct replacement of the several models of the Mity Mite Back Pressure Regulators, specifically models 91W, S91W, S91LW, and S91XW.
