Pressure Surge (Water Hammer) can be greatly controlled by selecting the correct check valve i.e., Silent Checks shut off very fast, 1/20th to 1/10th second, making excellent surge protection devices when pumping short distances less than half a mile. Conversely, the Automatic Control Check Valve has extremely low (and variable) speed shut off; an excellent surge protection device when pumping long distances (more than half a mile).

No single check valve is all serving. For example, the Lift Check Poppet (Center Guided) would be excellent for clean fluid, but a poor selection for waste water because of the obstructive flow passages. Consider all aspects of your pumping application and refer to the [Check Valve Comparison Page] before making your selection.
