KLF Series High-Sensitivity Regulator

Brand: Swagelok Company
Request Information
The KLF series provides high-sensitivity pressure control of gases or liquids with minimum droop in both low-flow and low-pressure applications. 
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: 15 to 3,600, (bar: 1 to 248, kPa: 103.4 to 24,820)
  • Pressure Control Range: psig: 0 to 2 (bar: 0 to 0.14, kPa: 0 to 13.8) 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: 1/4" Female NPT
  • Actuator: Knob, Antitamper nut
  • Materials of Construction:
    • Enclosure: 316 Stainless Steel
    • Diaphragm: Alloy X-750
    • Poppet: S17400 Stainless Steel
    • Seat: PCTFE, PEEK
