Type-90 Miniature Precision Air Pressure Regulator - 1

Miniature Precision Accurate pressure regulation in a compact, lightweight package The Type 90 is a miniature precision air pressure regulator. This pressure regulator provides the highest level of regulation accuracy and repeatability available in a compact, lightweight housing. A force balanced pilot control maintains output pressure to within 0.05 psig (3.44 millibar) with minimal drift over time. The Type 90 is ideal for applications that require exact pressure control and substantial flow capacity under variable operating conditions and limited space. •High resolution adjustment of set pressure •Precision Control Highly accurate air pressure regulation in a small package •Pressure ranges up to 120 psig (8 BAR) •Compact & Lightweight •Two gauge ports and reversible bracket allow front or back mounting Flow Capacity Exhaust Capacity Supply pressure sensitivity 0.5 psig (.034 BAR) for a 6.0 scfh (170 Nl/hr) maximum Approximate size (inches) 1.38 x 1.38 x 3.Í Temperature limits Port Size NPT/BSP Output Pressure Ranges Diecast aluminum alloy, chromate Zinc plated steel Additional materials Brass, aluminum, stainless steel, zinc plated steel FLOW CURVES

Type-90 Miniature Precision Air Pressure Regulator - 2

Manifold Mount Supply air is introduced to the inlet port, airflows through the supply side orifice and on top of the control diaphragm. That air then flows up through the housing nozzle and escapes out the housing vent. When the knob is adjusted to a setpoint, the range spring exerts a downward force against the signal diaphragm assembly. This force is transmitted to the flapper (ball), restricting airflow through the housing nozzle and creating backpressure against the control diaphragm. The backpressure will build until enough downward force to open the supply valve is achieved. Output...
