KBP Series General-Purpose Regulator

Brand: Swagelok Company
The KBP series is a high-sensitivity, general-purpose regulator designed to control back-pressure levels in analytical or process systems upstream of the regulator. 

The convoluted diaphragm provides excellent sensitivity and set-point repeatability. The metal-to-metal diaphragm seal minimizes the potential for leakage.
Features
  • Convoluted, nonperforated diaphragm
  • Metal-to-metal diaphragm seal
  • Low internal volume
  • Two-piece cap design provides linear load on the seal
  • 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
  • Ports:1/4" Female NPT, 1/4" tube butt weld, 1/4" VCR inlet
  • Actuator: Knob, Antitamper nut
  • Materials of Construction:
    • Enclosure: 316 SS, Brass
    • Seat: Fluorocarbon, Kalrez
    • Seal: PCTFE, PEEK
    • Stem: 316 SS
    • Diaphragm: Alloy X-750
