| Regulator | |||
| Your choices are... | |||
| Back Pressure Regulators | Back pressure regulators control upstream (inlet) pressure. They function similarly to relief valves. | ||
| Change Over Regulators | Change-over-regulators are combination valves and pressure regulators, fitted to a multiple-cylinder assembly that will automatically change over from a cylinder in use to a reserve cylinder at a predetermined pressure. | ||
| Differential / Bias Regulators | Differential pressure regulators, or bias pressure regulators, maintain constant differential pressure between a reference pressure and the pressure of the controlled fluid. | ||
| Filter, Regulator, Lubricator Assembly (FRL) | Filter, regulator, lubricators (FRL) are pre-packaged or modular assemblies of common configurations of air filters, regulators, lubricators and gauges. | ||
| Point of Use Regulators | Point of use regulators are installed directly into fluid lines. They are single stage regulators that are used to provide point-of-use pressure monitoring and control. Point of use regulators are often referred to as line regulators. | ||
| Pressure Reducing Regulators | Pressure-reducing regulators are used to provide a sub-circuit with a supply of fluid at a pressure that is less than the pressure in the main circuit. | ||
| Two Stage Regulators | Two-stage gas regulators reduce cylinder pressure in two steps and should be used when constant delivery pressure is needed without periodic adjustment. | ||
| Vacuum / Absolute Pressure Regulators | Vacuum or absolute pressure regulators control fluid at low positive pressures or below atmospheric pressure (absolute pressure). | ||
| Other | Other unlisted, specialized, or proprietary regulators. | ||

| Controlled Pressure Range | Limits of adjustment control. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Regulator Size | Valve size is the designated size of the valve by manufacturer. This typically represents the size of the passage opening. | ||

| ||
| Your choices are... | |||
| Gas (general) | Any type of gas, although generally excluding air. | ||
| High Purity Gas | High purity gas is designated by manufacturer as being applicable and built for high purity applications - includes nitrogen, argon, oxygen, hydrogen, and H.P. mixtures. | ||
| LP - Gas | Liquefied petroleum is a gas containing specific hydrocarbons that are gaseous under normal atmospheric conditions, but can be liquefied under moderate pressure and temperatures. Propane and butane are examples. | ||
| Natural Gas | Natural gases are liquid hydrocarbon mixtures that are gaseous at reservoir temperatures and pressures, but are recoverable by condensation or absorption. | ||
| Sour Gas | Sour gas is hydrogen sulfide (H2S) laden gas. | ||
| Specialty / Corrosive Gases | Specialty corrosive gases. | ||
| Other | Other unlisted, specialized, or proprietary media. | ||
