Improved Diaphragm - constructed of durable reinforced, laminated Neoprene Polycarbonate shatter resistant gauge lenses Auto reset safety relief valve Extremely Accurate - accurate within +/- 2% of actual gauge reading for both pressure regulators and flowgauges. High Capacity - Series 30 has high flow capabilities. Quality - Industrial grade Series 30 regulators are made in the USA from high quality, corrosive resistant materials. Series 30 regulators are covered by a 3 year limited warranty. New design features provide extreme accuracy, dependability and extended service life. Decay/Rise - As pressure drops in the gas cylinder, regulator outlet pressure will automatically increase. This is known as decay/rise. Smith® Series 30 regulators are designed to minimize this effect resulting in reduced gas costs, reduced cylinder handling and improved accuracy.Specifications Gas service - CO2 Compact Design Machined Brass Body Neoprene/Nylon Diaphragm 2” (51mm) Diameter Gauges Protective Inlet Filter - Sure-Seat™ Self Re-Seating Pressure Relief Valve 0 - 4000 Inlet Gauge 10 - 50 SCFH Delivery Gauge Show more
