TROUBLESHOOTING & REPAIR 

AIR CONTROL (cont’d) 

11.2 

 

RELIEF VALVE (cont’d)

 

There is another set screw at the other end of the valve, removing this allows the valve to be 
completely disassembled. When taking the valve apart be sure to lay the parts out in the order in 
which they were removed to facilitate assembly. Reverse the order to assemble. Pressurize the 
valve to check the setting of the valve. Remove the pressure and adjust as necessary to set the 
pressure. Turning the screw clockwise increases the pressure at which the valve will relieve. 

 
LP INPUT CHECK VALVE

, Same as the HP check valves except for size. During test insure that 

the valve is not leaking by pressurizing the HP section and check the LP input for air leaking out of 
the input. 
 

DIVER’S PRESSURE GAUGE

, same as HP pressure gauges. 

 

DIVER’S OUTPUT VALVES

, 1/4 turn ball valves, to test, pressurize the input and turn the valves 

off, check that no air is leaking past the valve. The valves are repairable; they use Teflon seats 
which can be replaced. A maintenance kit is available from Amron. To replace, remove valve from 
system. Remove end pieces from valve, remove valve stem packing nut and remove stem. Teflon 
ball seal and stem packing can now be removed and replaced. To assemble, reverse process. 
 
 

DEPTH MONITORING 

11.3

 

 

PNEUMO VALVES

 are repairable, remove stem by removing handle and stem packing nut, 

unscrew stem. Inspect stem, stem screw threads, valve body screw threads, brass and Teflon 
packing washer, and stem seat (KEL-F).  Repair kits are available and include a complete stem 
assembly. Lubricate stem screw threads with Christolube grease, install stem assembly, and 
permanently tighten packing nut.  

 
PNEUMO GAUGE PROTECTOR

 valves are not field repairable. The procedure for setting the 

valves is to pressurize the pneumo system slowly using the HP regulator. The gauge protector 
should shut off pressure to the pneumo gauge at about the zero set point screw (110% of full 
scale). Do not exceed a pressure equal to Zero on the pneumo gauge. If the gauge protector has 
not shut off the pressure by this time, either the protector is defective or not adjusted properly. To 
adjust loosen the lock nut on the side of the gauge protector valve and adjust the slotted screw on 
the valve. Turning the screw in (clockwise) increase the pressure at which the valve locks the 
pressure out. Set the lock-out to occur at about the zero adjusting screw, tighten lock nut and 
retest. 
 

PNEUMO GAUGES

 are not field repairable nor are there any adjustments which can be made in 

the field. Check to make sure the blow-out plugs are in place. Calibrate every 6 months. Check the 
zero position of the gauge a displaced zero is evidence of a gauge that has been subjected to 
over-pressurization.  
 

NOTE

: Check the gauge before using, if there is any question about the gauges integrity, have the 

gauge calibrated. Normal variations in zero are caused by variations barometric pressure or 
changes in altitude. These variations normally will not exceed 10 feet.
