(Color online) Cross sectional view of the fast-opening valve. #1, blue: valve gate with plate and holder complete; #2, red: MONOVAT seal; #3 yellow: bonnet seal, #4, green: bellows; #5, violet: actuator piston; #6, orange: mechanical latch.
Four pictures at 0.6, 2.6, 3.6, and 5.5 ms (start time of opening phase at 0 ms) during the opening phase of the valve taken by the high-speed camera. The reference point to characterize the opening process is marked. The ring segment shown to the right of the valve plate belongs to the holder of the same.
Moved distance of the reference point of the valve plate during the opening phase. Triangles mark points where the reference point is not visible. Resolution on time scale is 0.1 ms.
Open area of the gate valve versus time during the opening phase. The maximum open area is 12.6 cm2 corresponding to the inner diameter of 40 mm of the valve body. Triangels mark points where the open (the two symbols to the left) or still covered area (two symbols to the right) was not visible due to the viewport size. Resolution on time scale is 0.1 ms.
