Series 40 Heavy-Duty single-stage regulator regulators are extremely durable and contain our exclusive Sure Seat filtered seat technology for the extended seat and regulator life in the most demanding industrial applications. They feature a stainless steel diaphragm that allows for use with liquid gases, all brass construction that will stand up to corrosive atmospheres, and 2.5-inch (64 mm) brass case gauges.

  • The Series 40 regulator is constructed with a super-fine 15-micron, nickel-plated bronze filter that encapsulates the high-pressure seat.
  • This filter protects the seating surface from contamination by external debris that may enter the regulator during operation.
  • This in turn will reduce failures and dramatically extend the regulator's service life.
  • Series 40 regulators are constructed with a durable yet sensitive, stainless steel diaphragm for long dependable service life in most any environment.
  • These designs are capable of much higher gas flows than the current Smith 1500 series regulator models.
  • Some models are capable of producing flows of over 16,000 SCFH, up to 25% higher than comparable competitors' heavy-duty regulators.
  • They also provide extremely accurate outlet pressure of approximately ±2% of the actual gauge reading (center of the scale).
  • Decay/Rise is also very low at only .4 PSIG outlet rise per 100 PSIG tank pressure decay, helping maintain consistent and highly accurate outlet pressures and flows.
  • This design eliminates the need for diaphragm replacement in the event of over-pressurization.
  • The stainless steel diaphragm is suitable for use with liquid (cryogenic) gases.
  • Miller's True Blue Warranty delivers unparalleled peace-of-mind. 3 years.
