Product catalog summary

Overview: The document serves as a comprehensive guide on HAM-LET gas regulators, specifically the HRG series, designed for high purity gas applications. It covers single-stage and dual-stage regulators, their specifications, and applications across various industries.

Quick Selection Guide: This section provides a quick reference for selecting the appropriate regulator based on application, pressure, and stage requirements. It includes a table summarizing inlet and outlet pressures, Cv values, and corresponding series.

Pressure Regulator Fundamentals: The document explains the working principles of single-stage and dual-stage regulators. Single-stage regulators adjust pressure in one step, suitable for short-duration applications, while dual-stage regulators provide consistent pressure over longer durations by adjusting in two steps.

Regulator Selection Considerations: Key factors for selecting a regulator include the type (single or dual-stage), inlet/outlet pressure range, body material (stainless steel or brass), and purge system options. The importance of Cv and Kv factors in determining flow efficiency is also discussed.

Gas Purity Values: The document outlines the purity levels for gases, ranging from pure gas (99.5%) to ultra-pure gas (99.99999%), with corresponding maximum contamination levels in ppm.

HRG Series Features: The HRG series is designed for high purity applications, ensuring minimal leakage and high safety standards. The regulators are suitable for industries such as pharmaceuticals, semiconductors, and food processing.

Single-Stage Regulators: Detailed descriptions of various single-stage regulators, including the HRG5S, HRG5SL, HRG5SC, and HRG4S series, are provided. Each model's features, materials, and pressure options are outlined.

Dual-Stage Regulators: The document describes dual-stage regulators like the HRG5D series, emphasizing their ability to maintain constant delivery pressure despite changes in cylinder pressure.

Accessories and Additional Features: Information on available accessories and additional features for the regulators is provided, ensuring comprehensive solutions for gas regulation needs.

PRESSURE REGULATOR FUNDAMENTALS TYPE OF REGULATORS SINGLE-STAGE REGULATORS DUAL-STAGE REGULATORS High-pressure gases enter through the inlet of the regulator to the high-pressure chamber. When the hand wheel is turned clockwise, it compresses the spring and creates a force on the diaphragm, which pushes the regulator's poppet open. This releases the gas into the low-pressure chamber, exerting an opposing force on the diaphragm, which then closes the passage. A dual-stage regulator functions like two single-stage regulators connected in line. The first stage reduces the inlet pressure to a preset...

REGULATOR SELECTING CONSIDERATIONS: Max Contamination ( ppm) Purity lavel (degrees) Single-stage pressure regulators reduce the cylinder pressure to the delivery or outlet pressure in one step. Two-stage pressure regulators reduce the cylinder pressure to a working level in two steps. The best recommended action is to determine for time span is required to reach the regulated pressure consistency in the designated application. Generally, a single-stage regulator is good for short duration applications; a two-stage regulator is good for long duration applications, such as gas chromatography. 2....
