The MESA Series 100 Specialty Gas Regulators are precision manufactured from machined bar stock. This design minimizes contamination of the gas stream by in-board diffusion of atmospheric contaminates; as well as, cross-contamination of the gas stream frequently encountered with less expensive forged body regulators. The addition of chrome plating to the brass body helps to protect the outside body of the regulator from corrosive ambient conditions such as found in chemical plants and refineries. The single stage cylinder regulator is recommended where delivery pressure must be maintained constant as the cylinder pressure decreases. These regulators are ideally suited for continuous withdrawal of gas from pressurized cylinders. Brass bodies are recommended for non-corrosive gases. Chrome plated brass bodies are also recommended for non-corrosive gases. Monel and Hastelloy bodies are available upon special request.
