PAX1 Model 4100A High-Capacity Low Pressure Regulator
Brand: Fairchild Industrial ProductsRotork 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
