KHF Series High-Flow High-Sensitivity Regulator

Brand: Swagelok Company
The KHF series combines the high-flow capabilities -1.0 Cv - of a bulk distribution regulator with the high sensitivity and accuracy of a point-of-use regulator.
Features
  • Large-diameter convoluted, nonperforated diaphragm for increased pressure sensitivity
  • Metal-to-metal diaphragm seal
  • High-flow dual-gauze type filter positively retained in inlet port 
  • Maximum Inlet Pressure: psig: 100 to 3,600, (bar: 6.89 to 248, kPa: 689.5 to 24,820)
  • Pressure Control Range: psig: 0 to 10 (bar: 0 to 0.689, kPa: 0 to 68.9) through psig: 0 to 250 (bar: 0 to 17.2, kPa: 0 to 1,724)
  • Maximum Operating Temperature:
    • 80°C (176°F) with PCTFE
    • 200°C (392°F) with PEEK 
  • Process Connection: 1/2" Female NPT
  • Actuator: Knob, Antitamper nut
  • Materials of Construction:
    • Enclosure: 316 Stainless Steel
    • Diaphragm: Alloy X-750
    • Poppet: S17400 Stainless Steel
    • Seat: PCTFE, PEEK
