" wave anticipation valve " opens when the line has a vacuum due to the wave and will close later when the the nominal pressure is reached, end of surge. ( like Dorot S300-REEL or Bermad MN-735 )
Good afternoon
I would like to know your experience with 2 devices that I have observed in some installations to reduce the effects of surge pressures:
a) Dynamic combination air valve (cushioned closing)
b) Surge anticipation valve.
Would they be efficient and reliable?
How could they be...
