Fluid Pressure Gage.

SECTION I (Con't.)

The compensator control (20-Fig.8)

1-30 Compensator Control.

located in the extreme left corner of the test control panel, is

adjusted for the desired discharge pressure of the test stand. A

locknut is provided to secure the control in adjustment.

The fluid pressure gage (1-Fig.8),

1-31 Fluid Pressure Gage.

mounted on the stand control panel, is a needle-indicating, direct-

The dial is graduated from 0 to

reading, pressure actuated gage.

When the test stand is in operat-

6000 psi in increments of 50 psi.

ion the fluid pressure gage indicates the discharge pressure

selected by the compensator control.

1-32 Gage Snubber Valve. The gage snubber valve (17-Fig.8),

located below the pressure gage on the test stand control panel, is

a needle-type valve provided to admit pressure to the fluid pressure

gage.

1-33 Fluid Pressure Gage Tap.

The fluid gage tap (12-Fig.8), extend-

ing through the test stand control panel, is provided for the connect-

ion of a test pressure gage to check the accuracy of the fluid

pressure gage.

1-34 Filter Pressure Gage.

The filter pressure gage (5-Fig.8),

mounted on the test stand control panel, is a needle-indicating,

direct-reading, pressure and vacuum actuated, compound-type gage.

When used in conjunction with the pressure selector valve, the

filter pressure gage indicates pressure drop through the low pressure

filter. An indicated pressure drop of 20 psi necessitates replace-

ments of the low pressure filter element.

1-35 Pressure Selector Valve.

The pressure selector valve (15-Fig.8),

located directly below the filter pressure gage is a two-way, plug

type valve utilized to switch the filter pressure gage connection
