OBIT valve test and working pressure

Like other valves, perhaps the introduction of nitrogen or carbon dioxide in the idle system to validate the configuration of pressure.

The usual precautions for work with gases apply here. The factory default setting for 0/50 psig) range of 30 psi. For 30/100 psig) measuring range 60 pounds per square inch. Because these valves are adjustable, this parameter may be changed in accordance with the system.

The main goal of the " OBIT " maintaining valve evaporator pressure above a certain time during the minimum load. Valves, selected on the basis of differential pressure at full load. However, they should be adjusted to maintain the minimum required pressure in the evaporator under minimal load.

These valves can be adjusted by removing the cover, and turning the adjusting screw with Allen key size. Clockwise rotation increases the valve assemblies and counterclockwise decreases the value of the parameter. To find the correct value, the gauge should be used at the valve input is required. Thus. influence of corrections, which can be observed.

When these valves are installed in parallel, each of which must be adjusted in the same amount. If one valve was corrected on more than others, the best performance will happen if and adjusted all the way in before dumping them in equal quantities.
