Extra 50 points if you can justify your answer!
T/F : If a Float Trap fails to remove air and non-condensible gases (trapping those gases), there is an increased risk of waterhammer.
True
+50 : If a float trap fills with air, then it won't allow condensate to fill it, raise the float ball and open the trap, so it fails closed. This causes condensate to backfill, increasing the risk of waterhammer.
Using the Series 2000 Instruction Manual, identify which Configuration of Series 2000 is a double-seat, reverse-acting valve:

What are the advantages of a direct-op regulator over a pilot-op regulator?
Direct-Op, compared to the Pilot-Op:
- Fastest responding
- More cost-effective
- Easier to maintain (simpler design)
Extra 50 points if you can justify your answer!
T/F : Control lines don't always need to slope down away from the pilot.
False
+50 : Sloping away from the pilot
- prevents condensate from collecting in the pilot
- maintains accurate pressure readings.
Extra 50 points if you can justify your answer!
If the Dura-Flo bucket trap isn't primed during install, will the trap fail open or closed?
Closed
+50 : Without submersion in water, the bucket will never float up to open the trap.
