Flange, Butt Weld Feature: 1, Tilting disc check valves produce slightly
more pressure drop than swing check valves of the same size. These check
valves have a single-piece disc without a hinge. In response to flow
forces, the disc pivots about hinge pins that are located within the
geometry of the disc and slightly above the center-line of the valve
body. Due to the disc rotating onto the seat, the sealing surfaces must
be conical. Some tilting disc check valves include a counterweight on
the disc, dramatically increasing the disc stability with lower flow
rates. 2, Tilting disc check valves were designed specifically to
minimize the potential for high-energy water hammer. This objective is
accomplished by locating the disc center of rotation a short distance
from its pivot point, thus allowing the disc to quickly close with flow
stoppage or flow reversal. Although it is best to size this valve to be
fully open, the disc is reasonably stable under some less than full-open
flow conditions. 3, When it comes to maintenance, tilting disc check
valves are more challenging than swing check valves. To keep seat
leakage to a minimum, the conical seating surfaces of the disc and in-
body seat must mate well, and the disc pivot location must be precise.
