Mity Mite Back Pressure Regulator

  • Improved precision, even with two-phase flow
  • Equilibar BPRs are available in Hastelloy C and exotic allows such as titanium, zirconium, and PEEK
  • BPRs are typically in stock for shipment within one week

The Mity Mite was originally introduced back in the 1960’s by a company called Grove and has since been common-place across many fluid control applications, ranging from amateur rocketry to petrochemical research applications. However, in recent years, many customers in the chemical research arena reported problems with supply and service for these products and since 2015 customers have been faced with the total withdrawal of these products from the market.

For legacy applications that require an exact drop-in replacement, Equilibar can meet your needs with replacement diaphragms and BPR.

The Mity-Mite BPR is an excellent control valve and has many successful applications. However, the Equilibar® back pressure regulator offers several distinct advantages over the traditional Mity Mite design:

• Through the use of Kalrez FFKM o-rings, the Equilibar Research Series regulators can operate up to 300C and can be cycled repeatedly without leaks

• Standard designs available to 6000 and 10,000 psig

• Low dead-volume (approximately 0.2 ml) using 1/16″ HPLC tube fittings

• Wide variety of diaphragms available (PTFE, PEEK, SS316L, Hastelloy C276, Polyimide)

While the Mity-Mite and the Equilibar back pressure regulators work in a fundamentally similar way, the unique design of the Equilibar gives it much more sensitivity, especially in the low to medium pressure range. Because the Equilibar diaphragm is thinner and more supple than the Mity Mite, it can be used at very low pressures (less than 1 psig, or in the millibar range).
