Regulator Type
   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.

Specifications
   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.

Media Description
           
   Your choices are...         
   Gas (general)       Any type of gas, although generally excluding air. 
   Gasoline / Diesel Fuel       Gasoline / diesel fuel is a mixture of flammable liquid hydrocarbons derived chiefly from crude petroleum and used as a fuel for internal-combustion engines. 
   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.
