Product catalog summary

General Overview
Vacuum regulators are designed to feed gases such as chlorine, and with minor modifications, can also be used for other gases like SO2, CO2, and NH3. These regulators operate on the indirect vacuum principle and are constructed from high-quality, resistant materials including tantalum alloys, pure silver, and various plastics to ensure reliable operation under high mechanical and temperature stress.

Operation Principle
The gas pressure builds up at the back adapter of the regulator. An inlet valve prevents uncontrolled gas entry. When sufficient vacuum is generated by the ejector, chlorine gas travels through the vacuum line, flow meter, and rate valve to the ejector, where it mixes with water. The feed rate is adjustable via the precision rate valve. An optical indicator signals when the chlorine cylinder is empty, with optional pressure gauges and switches for electronic alerts.

Components and Materials
The vacuum regulator consists of several components including the casing, rate valve, flow meter, springs, washers, adapter, inlet valve, ejector casing, membrane, and non-return valve. These are made from high-quality materials to ensure durability and performance.

Technical Specifications
The capacity of the vacuum regulators can reach up to 200 kg/h. Dimensions are provided with and without pressure gauges. The dosing range varies, with specific values provided for different configurations. Connection standards include DIN, CGA, and BSP, with accuracy within 4% of flow.

Options and Order Codes
Various options are available, including alarm signals, gas type specifications, rate valve inclusion, dosing range selection, pressure gauge inclusion, and yoke type. Order codes are structured to reflect these options, allowing for customization based on specific requirements.

Conclusion
This document provides detailed specifications and operational guidelines for vacuum regulators used in dosing aggressive gases. The focus is on ensuring reliable performance through high-quality materials and precise control mechanisms.
