surge relief valve

surge relief valve

surge relief valve

Gere's my scenario: Water transfer pump. Static head on the system is about 395 feet, which we're pumping (VFD) against to deliver water to a tank some 1.4 miles away. Using a GA Industries 4" surge relief valve, low velocity of 5 fps (1650 usgpm), to be set to discharge to waste (may change this to discharge to suction). I'm going to set the valve to open at 10% higher than my system working pressure. I plan to set the surge relief valve to close just above my maximum static pressure to ensure I don't drain the tank. Does this sound reasonable? Any comments welcomed. Thanks.


RE: surge relief valve


If that is what your surge analysis told you, you should be fine.  To me, it would seem someone didn't do enough for you in the study.  You do have a surge analysis?

If not invest in one.  I have concerns with some of what you posted.  Your system has a lot of energy, which could be very dangerous if not addressed correctly.  You are right in anticipating surge relief....The extra step of an analysis wont cost that much.
