Pressure Reducer Adjustable Pressure

 

Features

R14, R16

Non-relieving models for air and water service

Relieving models for air service allow reduction of

outlet pressure even when the system is dead-ended

R14 has aluminum body and bonnet

R16 has brass body and bonnet

** The 8th and 9th positions of the model number contain the Modified Outlet Pressure Setting. The Modified Outlet Pressure Setting is the desired outlet pressure,

modified to allow for inlet pressures other than 100 psig, and for flows other than zero. Insert the modified outlet pressure setting in positions 8 and 9 as described below.

1. Write down the desired outlet pressure and the flow through the regulator. EXAMPLE: 30 psig outlet pressure at 10 scfm flow.

2. Modifications for inlet pressures other than 100 psig:

If inlet pressure exceeds 100 psig*, add 1 psig to the desired outlet pressure for each 20 psig the inlet pressure is above 100 psig*.

EXAMPLE: If the inlet pressure is 180 psig, add 4 to the desired outlet pressure. Following through with the example in step 1, add 4 to 30 for a modified outlet pressure setting of

34 psig.

If inlet pressure is less than 100 psig*, subtract 1 psig from the desired outlet pressure for each 20 psig the inlet pressure is below 100 psig*.

EXAMPLE: If the inlet pressure is 60 psig, subtract 2 from the desired outlet pressure. Following through with the example in step 1, subtract 2 from 30 for a modified outlet

pressure setting of 28 psig.

3. Modifications for flows other than zero:

Determine the pressure drop from the appropriate flow curve above. Add the pressure drop to the modified outlet pressure setting.

EXAMPLE: If the desired outlet pressure is 30 psig at a flow of 10 scfm, add 10 to the modified outlet pressure setting. The quantity of 10 is the difference between the outlet

pressure (30 psig) at the desired flow (10 scfm) and outlet pressure (40 psig) at no flow. See dashed lines on the air flow curve for example. Following through with the first

example in Step 2 above, add 10 to the 34 to obtain a modified outlet pressure setting of 44. Enter 44 in the 8th and 9th positions of the model number.

* 125 psig for outlet pressure settings of 95 through 99 psig.
