AIR BLEED VALVES<br />
PR<br />
Pressure:3000 psi<br />
Closing Pressure:6 psi is<br />
required to hold valve closed.<br />
Closing Time:Approximately<br />
8 seconds with 1000 psi pump<br />
outlet pressure to 18 seconds with<br />
250 psi pump outlet pressure.<br />
Opening Time:Approximately<br />
10 minutes after pump shutdown.<br />
Flow rate to close:<br />
•Size N: 1.3 gpm<br />
•Size Q: 2.5 gpm<br />
•Size S: 4.0 gpm<br />
Temperature:Under normal<br />
conditions of continuous operation,<br />
fluid temperature should not<br />
exceed 130°F (54°C). In no<br />
instance, should the temperature<br />
exceed 160°F (71°C).<br />
The function of the automatic air<br />
bleed valve is to allow a pump<br />
to prime when stating against a<br />
closed system with air trapped<br />
in the suction side.<br />
