Safe Product Selection:
The complete catalog contents must be reviewed to ensure that the system designer and user make a safe product selection. When selecting products, the total system design must be considered to ensure safe, trouble-free performance. Function, material compatibility, adequate ratings, proper installation, operation, and maintenance are the responsibilities of the system designer and user.
Caution:
Do not mix or interchange valve components with those of other manufacturers.

General-Purpose Diaphragm-Sensing, Pressure-Reducing Regulators (KPR Series)

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

Technical Data

Maximum Inlet Pressure

  • 3600 psig (248 bar)
  • 6000 psig (413 bar) with PEEK seat

Pressure Control Ranges

  • 0 to 10 psig (0.68 bar) through 0 to 500 psig (34.4 bar)

Flow Coefficient (CV)

  • 0.06 and 0.20
  • 0.02 and 0.50 also available

Maximum Operating Temperature

  • 176ºF (80ºC) with PCTFE seat
  • 392ºF (200ºC) with PEEK seat
  • 212ºF (100ºC) with PEEK seat and maximum inlet pressure greater than 3600 psig (248 bar)

Weight

  • 2.4 lb (1.1 kg)

Ports

  • 1/4 in. female NPT inlet, outlet, and gauge ports (all body materials)
  • 1/4 in. tube stub inlet, outlet, and gauge ports (316 SS body material only)
  • 1/4 in. VCR® inlet, outlet, and gauge ports (316 SS body material only)

 

High-Flow, High-Sensitivity Diaphragm-Sensing, Pressure-Reducing Regulators (KHF Series)

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
  • Balanced poppet for supply-pressure effect of approximately 0.2%
  • High-flow dual-gauze type filter positively retained in inlet port

Technical Data

Maximum Inlet Pressure

  • 3600 psig (248 bar)

Pressure Control Ranges

  • 0 to 10 psig (0.68 bar) through 0 to 250 psig (17.2 bar)

Flow Coefficient (CV)

  • 1.0

Maximum Operating Temperature

  • 176ºF (80ºC) with PCTFE seat
  • 392ºF (200ºC) with PEEK seat

Weight

  • 4.4 lb (2.0 kg)

Ports

  • 1/2 in. female NPT inlet and outlet
  • 1/4 in. female NPT gauge port

 

High-Flow Piston-Sensing, Pressure-Reducing Regulators (KPF Series)

The KPF series provides minimum droop across the flow range with high accuracy of outlet pressure.

 

Features

  • High flow coefficient (CV=1.0)
  • Balanced poppet for minimal supply-pressure effect
  • High-flow, dual-gauze type filter positively retained in inlet port

Technical Data

Maximum Inlet Pressure

  • 6000 psig (413 bar)

Pressure Control Ranges

  • 0 to 1000 psig (68.9 bar) through 0 to 4000 psig (275 bar)

Flow Coefficient (CV)

  • 1.0

Maximum Operating Temperature

  • 176ºF (80ºC) with PCTFE seat
  • 392ºF (200ºC) with PEEK seat

Weight

  • 4.5 lb (2.1 kg)

Ports

  • 1/2 in. female NPT inlet and outlet
  • 1/4 in. female NPT gauge ports
