Harris Two Stage Ultra High Purity Brass Barstock Regulator

Introducing the Harris Two Stage Ultra High Purity Brass Barstock Regulator Model 721-125-580-PS, a precision instrument designed for the control of non-corrosive gases in high purity applications. This regulator is crafted with excellence, offering unparalleled performance and reliability for various scientific and industrial processes. Its robust brass construction ensures durability, while the single stage design ensures precise pressure control when pressure rise is not critical.

Key Features and Specifications

The Harris Model 721-125-580-PS is equipped with a 1-11/16"- 316L Stainless Steel diaphragm, which eliminates contamination from diffusion or outgassing, thereby maintaining the integrity of your gas supply. The one-piece encapsulated seat design, featuring a 10 micron sintered internal filter, protects the PTFE Teflon seat from particulate contamination. Additional features include an external relief valve for safety, brass barstock body, bonnet, and fittings, and dual scale gauges for precise pressure readings in both psi and bar. This regulator is designed to maintain gas purity levels with a 1 x 10-9 cc/sec inboard helium leak rate, ensuring optimal performance.

Applications and Benefits

Perfectly suited for high purity gas applications, research sample systems, process analyzers, gas chromatography, EPA protocol gases, laser gas systems, and emission monitoring systems, the Harris Two Stage Ultra High Purity Brass Barstock Regulator is a versatile and reliable solution. Its front or back panel mountable design offers easy installation and integration into various systems. Conforming to CGA E-4 standard for gas pressure regulators, this model guarantees compliance with industry standards. With a maximum inlet pressure of 3000 PSIG, except for models with CGA 300 and 510 that are equipped with a 400 PSIG inlet gauge, the Harris regulator is designed to meet the demands of a wide range of applications.
