Miller® | Smith Equipment® has heavy and medium duty as well as single, two and three stages regulators, among others.
Construction features
These regulators have seven key features, which are:
1) Resin bonnet insert
Allows smooth, easy adjustment even at high-pressure levels.
2) Stainless steel diaphragm
Resists corrosion, leaking and freeze-up if used with liquid (cryogenic) gases for extended service life. Note: Series 30 has neoprene composite diaphragm.
3) Color-coded labels
Supply performance capabilities, easy gas service identification and technical information.
4) External relief valve
Protects regulator from damage due to inadvertent high-pressure surge. Relief valve will release excessive pressure and automatically reset.
5) Nickel-plated bonnet
Along with brass body protect against corrosion.
6) Shatter-resistant gauge lenses
2.5-inch corrosion-resistant polished brass gauges with shatter-resistant polycarbonate lenses. Note: Series 30 has 2-inch painted steel gauges.
7) Dual filters including Sure Seat™
Protect high-pressure seat from debris for reliable operation and long service life.
