PAX1 Model 4100A High-Capacity Low Pressure Regulator

Brand: Fairchild Industrial Products
Rotork Fairchild's all new PAX1 Motor Set Pressure Regulator is a flexible low voltage DC powered linear actuator coupled to one of four Fairchild precision pressure regulators capable of controlling pressure ranges of 0-0.5 psig to 0-3,000 psig and housed in a flameproof enclosure. 

The unit is inherently lock-in-last-place as the actuator will maintain its position upon loss of electrical power. The Model 4100A is designed for applications requiring high flow capacity and accurate process control.
Features
  • Large area, high sensitivity diaphragm provides control sensitivity of 0.05" water column for precision control in low pressure applications
  • Pressure balanced supply valve prevents supply pressure changes from affecting the setpoint
  • Large relief valve provides high exhaust flow capacity
  • Soft seat valves minimize air consumption
  • Aspirator tube compensates for downstream pressure droop for flow demand
