The pressure versus flow curves provided in the graph Direct Acting Pressure Regulator Operating Map indicates the useful regulating capacity of the regulator When selecting a regulator engineers should examine pressure versus flow curves to ensure the regulator can meet the performance requirements necessary for the proposed application
A flow curve illustrates a regulator s performance in terms of outlet pres sure and flow rate Flow is not controlled by the regulator It is con trolled downstream by a valve or flow meter The curve shows you how a regulator will respond as flow in the system changes Look at the top curve in Figure 1 The curve starts at 400 psig This is the

Scuba diving trips in Antarctica and the Arctic If your primary regulator freezes and causes a free flow switch to your back up regulator and turn off the valve to the primary regulator We avoid rinsing regulators with fresh water between dives to minimize the
The Navy s primary interest is in avoiding regulator free flow under polar ice The breathing effort which is a focal point of the EN 250 standard is of lesser importance For instance the 1991 Sherwood SRB3600 Maximus regulators long used by the U S Antarctic program have been highly modified and detuned to prevent free flows
Typically the middle section of the regulator s flow curve between the choked flow and lock up pressure regions will be much more linear and level This is the ideal operating flow range for the regulator under the given set of inlet/outlet conditions In the event of an overpressure downstream a non relieving regulator would remain in the
How do flow regulators work A typical flow regulator consists of three components a housing a seating area a precision o ring The flow rate is determined by the interaction between the seating area and the o ring When water flows through the regulator
The possible variation in flow rate should also be considered to ensure the regulator will not fail in the desired application Too much or too little pressure can cause the regulator to malfunction Adjustment Air pressure regulators provide several methods of adjustment control Manual regulators typically use knobs or T handles Analog
