automatic Changeover regulators and systems

Product catalog summary

Overview: This document provides detailed specifications and operational guidelines for various automatic changeover regulators and systems, specifically focusing on low and high flow changeover regulators and systems. These systems are designed to ensure a continuous flow of gas for applications requiring stored gas supplies.

Specifications:

ACS012 - Low Flow Changeover Regulator: Maximum inlet pressure of 400 or 3500 psig, with delivery pressures ranging from 100 to 250 psig. Available in stainless steel, brass, or nickel-plated brass.
CS-2200 - Low Flow Changeover System: Maximum inlet pressure of 3500 psig, with delivery pressures from 25 to 150 psig. Available in stainless steel or brass.
ACS3200 - High Flow Changeover Regulator: Maximum inlet pressure of 3000 psig, with delivery pressure of 160/200 psig. Available in stainless steel or brass.
CR441800 - High Pressure Changeover System: Maximum inlet pressure of 3500 or 6000 psig, with delivery pressures from 500 to 2000 psig. Available in stainless steel or brass.

Applications: These systems are suitable for CO2 supply in tissue and cell culture incubators, shielding and laser assist gases in metal fabrication, analyzer carrier gas, and laser cutting assist gas.

Material and Design: The systems are constructed using high-quality materials such as 316 stainless steel, brass, and nickel-plated brass. They feature diffusion-resistant metal diaphragm seals to ensure gas purity and integrity.

Operational Parameters: The systems are designed to operate under specific pressure ratings per ANSI/ASME B31.3 criteria, with a design proof pressure of 150% of maximum operating pressure. They maintain a bubble-tight internal leak rate and are designed to meet external leak rates of ≤ 2 x 10-8 atm cc/sec He.

Additional Features: The systems include standard mounting brackets, and gauges are available in stainless steel or brass, depending on the regulator material. Cleaning standards comply with CGA 4.1 and ASTM G93.

Functional Description: The changeover systems automatically switch between primary and secondary gas supplies to maintain continuous flow. The systems are equipped with handknobs for manual switching and replenishment of gas supplies.

Part Number Selector: The document includes a detailed guide for selecting part numbers based on series, body material, pressure settings, and other specifications.

Safety Warning: Users are advised to read and understand the safety, installation, and operation precautions before using the product.
