High-Purity, High-Flow Gas Regulators (HF Series)

high-purity-high-flow-gas-pressure-reducing-dome-loaded-regulatorsSwagelok® HF series gas pressure regulators use a gas-actuated pressure-sensing assembly to precisely control outlet pressure.

medium-to-high-pressure-pressure-reducing-spring-loaded-regulatorsThe KPP series meets the demands of a wide range of gas or liquid applications in a lightweight, compact installation footprint. These features make the KPP pressure regulator and ideal pressure control solution within high-density OEM equipment.

Two-Stage Diaphragm-Sensing, Pressure-Reducing Regulators (KCY Series)

two-stage-pressure-reducing-spring-loaded-regulatorsThe KCY series is designed for use in applications requiring constant outlet pressure even with wide variations in inlet pressure. This two-stage regulator is comparable to two single-stage regulators connected in series. The first stage is factory set to reduce the inlet pressure to 500 psig (34.4 bar). The second stage can be adjusted with the handle to achieve the required outlet pressure.

 

This two-stage arrangement minimizes the supply-pressure effect caused by fluctuating inlet pressure, such as with a depleting gas cylinder. As inlet pressure drops below the setting of the first stage, the regulator then functions as a single-stage regulator. The first-stage pressure setting can be reduced while monitoring the pressure at the interstage port, but lower flow may result.

 

Features

  • Convoluted, nonperforated diaphragm
  • Metal-to-metal diaphragm seal
  • Excellent set-point stability
  • Supply-pressure effect of approximately 0.01%
  • High-flow, dual-gauze type filter positively retained in inlet port
