CORROSIVE GAS REGULATORS
Model ARG
Aluminum, Single-Stage, Bar Stock Regulators
Model ARG is a single-stage regulator designed for use with Anhydrous Ammonia, Hydrogen Sulfide, Sulfur Dioxide and other gases compatible with aluminum.
These regulators are ideal for applications requiring the light weight of an aluminum body regulator.
Warning: Do not use this regulator with Oxygen.
Standard Features
- Aluminum Body can be used with certain gases not compatible with brass, without the expense associated with stainless steel.
- Large effective diaphragm sensing area provides quick response, accurate and dependable regulation and long service life.
- Filter traps foreign matter, extends regulator life and reduces maintenance.
- Outlet Metering Valve provides flow control.
- 1?8" NPT Female Bonnet Vent Port allows bonnet to be connected to a vent line or disposal system as a precaution in the unlikely event of
a diaphragm failure.
Optional Features
- Mounting Ring permits regulator to be panel mounted.
