Regulator Selection

Our local Swagelok Field Engineer is also available to help size regulators for your system. To select a pressure regulator, flow curves will allow you to select the option that works best for your requirements. Learning about flow curves ahead of time will make it easier for you to review your options with the field engineer. Learn about flow curves here.

To select a regulator, the major considerations are inlet pressure, outlet pressure and system media. Our Swagelok field engineer can help you to understand these requirements:

Regulator function 
        1. Pressure-reducing 
        2. Back-pressure 
        3. Changeover 
        4. Vaporizer 
        5. Tank blanketing
Inlet Pressure Range - Match to maximum supply pressure
Pressure Control Range 
        1. Match maximum outlet pressure - Your flow requirements may dictate a higher control range
Flow Requirements (Use flow curves) 
System Compatibility 
        1. Materials of construction for the body, diaphragm, seat and o-ring
System Functionality - Helps in determining venting options and accessories
End connections, porting, and mounting
Ancillary components 
        1. Upstream filtration 
        2. Isolation valves
