Regulator Type




   Regulator       
   Your choices are...
 
      
 
   Regulator (general)
 
     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).

Specifications




   Port 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.
   Pressure Rating
 
     Maximum safe pressure value for which the valve is rated.
 
   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.
   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.
   Vacuum Control Pressure
 
     Maximum safe vacuum pressure for which the valve is rated.
 
   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.

Features




           
   Your choices are...
 
      
 
   Breathable Air
 
     Breathable air is free of contamination and is suitable for inhalation.
 
   Cartridge / Manifold Valves
 
     Cartridge valves are directional control valves that are inserted into manifolds to provide a cost-effective, compact system design.
 
   Severe Service Rated
 
     The valve is designated by manufacturer as being suitable for severe service applications where there is continuing operational, maintenance or reliability issues with a given application.
 
   Lockout / Tamper Proof
 
     The valve has a device to prevent unauthorized use.
 
   Cryogenic Valves
 
     Designated by manufacturer as being applicable to extreme cold applications such as for liquid gas and refrigerants.
 
   Fire Service
 
     Designated by manufacturer as being applicable for use in fire service or fire fighting applications.
 
   Other
 
     Other unlisted, specialized or proprietary feature.
