gas diaphragm valve for sale, brand-new and used.

I am selling a fairly new Harris 9296NC Two Stage Regulator for Welding - Argon, Helium, Nitrogen This was originally purchased to fill helium balloons, but is no long needed. The regulator was only used a handful of times and contains a 60 PSI max output gauge and a barbed output valve with a quick shut-off valve. This regulator is sold at AIRGAS and MCMASTERCARR for $320.

For your consideration is a like new AirGas High Purity Automatic Compressed Gas Changeover Panel 2 Cylinder 2 Hose CGA580 connections with 33" Stainless Steel hose *Gas Service: Arsine, Carbon Monoxide, Deuterium, Deuterium Selenide, Diborane, 1,1 Difluoroethylene, Ethane, Ethylene, Germane, Hydrogen, Hydrogen Selenide, Methane, Methyl Fluoride, Methylene Fluoride, Natural Gas, Pentaborane, Phosphine, Silane, Stibine, Tetrafluoroethylene, Vinyl Fluoride. Yikes! Model: Y11CP120R350 Y13-CP145DRE

This is a new regulator, I think. I don't remember ever using it. I can't find any indication that it has been used.

Texsteam Series 5000 Chemical Injector, Plunger Size 3/8" Operating Ratio Gas/Fluid: 497/1 Maximum Pressure (PSIG) Hard Packing: 12,000 Soft Packing: 3,000 DESCRIPTION Texsteam Series 5000 chemical injectors are positive displacement units powered by integral gas/air motor.These pumps fill the requirements of a broad range of applications because of their ability to achieve high discharge pressures (up to 12, 000 psi) and wide volume ranges.

Series 5100 Air or Gas Driven Injector, Plunger Size: 1/4" Series Description: The 5100 Series Texsteam Chemical Injectors are single acting, positive displacement plunger-type pumps, powered by gas via a diaphragm with a spring return. Speed control is accomplished by regulating the exhaust gas discharge flow. Reversal is accomplished by a direct spring-actuated switching mechanism (rotary three-way valve).
