Media Description




           
   Your choices are...
 
      
 
   Gas (general)
 
     Any type of gas, although generally excluding air.
 
   Gasoline / Diesel Fuel
 
     A mixture of flammable liquid hydrocarbons derived chiefly from crude petroleum and used as a fuel for internal-combustion engines.
 
   High Purity Gas
 
     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
 
     Liquid hydrocarbon mixtures that are gaseous at reservoir temperatures and pressures but are recoverable by condensation or absorption. Natural gasoline and liquefied petroleum gases fall in this category.
 
   Sour Gas
 
     Hydrogen sulfide (H2S) laden gas.
 
   Specialty / Corrosive Gases
 
     Specialty corrosive gases.
 
   Other
 
     Other unlisted, specialized, or proprietary media.

Regulator Type




   Regulator       
   Your choices are...
 
      
 
   Regulators
 
     Regulators maintain a constant outlet pressure.
 
   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.

   Features       
   Your choices are...
 
      
 
   Stack Mounted
 
     The valve is constructed in a modular format, so that it can be assembled to create a valve block.  This type of valve is also referred to as a sandwich or modular valve.
 
   Severe Service Rated
 
     The valve is designated by manufacturer as being suitable for severe service applications where there are continuing operational, maintenance or reliability issues with a given application.
 
   Precision Control
 
     The valve has the ability to accurately control the flow or pressure.
 
   Lockout / Tamper Proof
 
     The valve has a device to prevent unauthorized use.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
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.
 
   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.
   Media Temperature
 
     Maximum temperature of media the valve is designed to accommodate.
