The Fairchild Model 70B Miniature Pressure Regulator is engineered for precise control in pneumatic instrumentation applications, especially where space constraints are a concern. Its compact design and robust construction make it an ideal choice for environments requiring reliable and accurate pressure regulation. Key Features Compact Design: The Model 70B’s small footprint allows for easy installation in tight spaces, making it suitable for applications with limited room. Durable Construction: Featuring a brass bonnet and valve body, along with zinc-plated steel trim, this regulator is built to withstand challenging environments. Vibration Dampening: An integral vibration damper ensures low-noise operation, enhancing performance stability. High Sensitivity: With a control sensitivity of 2.5 inches water column, the Model 70B delivers precise pressure adjustments. Minimal Supply Pressure Effect: It maintains a supply pressure effect of less than 1%, ensuring consistent output despite variations in supply pressure. Specifications Maximum Supply Pressure: 250 psig (17.0 BAR, 1700 kPa) Output Pressure Range: 1 to 60 psig (0.07 to 4 BAR, 7 to 400 kPa) Flow Capacity: 2.5 SCFM (4.25 m³/hr) at 100 psig (7.0 BAR, 700 kPa) supply and 30 psig (2.0 BAR, 200 kPa) setpoint Exhaust Capacity: 0.28 SCFM (0.48 m³/hr) when downstream pressure is 5 psig (0.35 BAR, 35 kPa) above a 20 psig (1.5 BAR, 150 kPa) setpoint Ambient Temperature Range: -40°F to +160°F (-40°C to +71°C) Applications The Fairchild Model 70B is ideally suited for pneumatic instrumentation applications where precise pressure control is essential, and installation space is limited. Its durable construction and high sensitivity make it a reliable choice for various industrial settings.
