If the leak develops through the packing, tighten the packing gland nut firmly with a wrench to reseat the 
packing around the valve stem, then back off the nut until loose, and finally retighten the nut finger tight.  
Tightening the packing nut too tight may cause erratic operation.  An occasional drop of oil on the valve 
stem at the packing nut will prolong packing life. 
 
If valve malfunctions, check for bent or binding, paint or corrosion on valve stem, foreign material in valve, 
erosion, or thermal system (capillary) failure.  If foreign material or scale is likely, the use of a strainer in 
the inlet water line is recommended. 
 

WATER SHUTOFF VALVE - WATER-COOLED HEAT EXCHANGER (Optional Equipment)

 (

Figure 5-3

)

 - A magnetic solenoid-operated water shutoff valve rated at 150 psig (10.3 bar) water pressure 

should be mounted in the water outlet line after the oil cooler.  The valve should be wired into the 
compressor control circuit so that the valve opens to allow water to flow any time the compressor is 
running.  When compressor stops under automatic control, or is shut off manually, the valve should close, 
stopping water flow through the system.  See Wiring Diagrams, pages 32 thru 35. 
 

 

 

 

Compressor, air/oil reservoir, separation chamber and all piping and tubing 
may be at high temperature during and after operation. 

 
 

OIL RESERVOIR

 - The oil reservoir-separator combines multiple functions into one vessel.  The lower 

half is the oil reservoir, providing oil storage capacity for the system and the top portion, a primary oil 
separation means.  The reservoir also provides limited air storage for control and gauge actuation.
