Type 91 Subminiature Regulator from Bellofram PCD is a compact, low-cost unit which operates in pressure ranges up to 100 PSI, with a maximum supply pressure of 250 PSI. It provides dependable reliability and accuracy for low flow or dead end applications, but is not designed for critical flow applications. The Type 91 subminiature regulator is available with a corrosion resistant anodized aluminum body and bonnet or with a brass body and bonnet. Both come standard with a fluorocarbon diaphragm.

Type 91 Low Bleed

The Type 91 low bleed version is designed for applications where low air consumption is required. The Type 91 is ideal for applications where space is limited and for dead ended/low flow service. Such applications include ink control on printing presses, panel loading applications, hand-held analyzers and calibration equipment, small cylinder operations, and all types of instrumentation applications. It can be through panel mounted or, due to its low weight, pipe mounted. A slotted adjustment screw is available for precision control.

  • Small package size and lightweight construction
  • Standard or low bleed versions available
  • Corrosion resistant anodized aluminum exterior
