PAX1 Model 11 Precision 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 11 is designed for applications that require moderate capacity and accurate low pressure control.
Features
  • Large area, high sensitivity diaphragm provides control sensitivity of 1/8" water column, allows use in precision applications
  • Pressure balanced supply valve prevents supply pressure changes from affecting the setpoint
  • Separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
  • An aspirator tube compensates downstream pressure droop for flow demand
  • Non relieving option available for applications requiring containment of gas
