KPR Series General-Purpose Regulator

Brand: Swagelok Company
The KPR series is a compact regulator with excellent accuracy, sensitivity, and set-point pressure stability.
Features
  • Convoluted, nonperforated diaphragm
  • Metal-to-metal diaphragm seal
  • Low internal volume
  • Two-piece cap design provides linear load on the diaphragm seal
  • High-flow, dual-gauze type filter positively retained in inlet port
  • Maximum Inlet Pressure: psig: 100 to 6,000 (bar: 6.9 to 413, kPa: 689.5 to 41,368)
  • Pressure Control Range: psig: 0 to 10 (bar: 0 to 0.68, kPa: 0 to 68.9) through psig: 0 to 500 (bar: 0 to 34.4, kPa: 0 to 3,447)
  • Maximum Operating Temperature:
    • 80°C (176°F) with PCTFE
    • 200°C (392°F) with PEEK
    • 100°C (212°F) with PEEK and inlet pressure greater then 3600 psig
  • Process Connection: 1/4" Female NPT, 1/4" tube butt weld, 1/4" VCR inlet
  • Actuator: Knob, Antitamper nut
  • Materials of Construction:
    • Enclosure: 316 Stainless Steel, Brass, Alloy
    • Diaphragm: Alloy X-750, Alloy C-276
    • Poppet: S17400 Stainless Steel, Alloy
    • Seat: PCTFE, PEEK
