text: If the valve is open when the solenoid is not energized, then the valve is termed normally open (N.O.).
text: In operation, the valve is fully open or closed when the disc is rotated a quarter turn.
text: When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid.
text: Although a sphere or a cylinder would theoretically be the most economical shape to resist fluid pressure when a valve is open, there are many other considerations.
text: This invention relates in general to valve structure and particularly to a type of such structure wherein the valve may be operated without the use of springs, and may be either normally open or normallyclosed depending only upon the manner of connecting supply and exhaust conduits thereto.
text: Thus, the. valve is. normally open whenever the operating handle 52 is in.
text: Accordingly, when the valve is closed there is a definite surface available at 81 to urge the valve leftwardly by which to hold the valve 76 firmly against the seat 79, but when said valve is open the entire area on the leftward side of the hub 77 is available to urge the valve rightwardly.
text: Thus, when the valve is closed as appearing in Figure 4, there is available not only the area 81 but also the area of the shoulder 82 for the action of pressure tending to hold the valve closed, but when the valve is open, the walls of the recess 83 will snugly receive the shoulder 82, shielding the radial surface of said shoulder from the action of pressure and thereby reducing the area available to pressure for urging the valve leftwardly.
text: For example, if lime or dirt deposits collected around the valve seat while the valve was open, there was interference when efforts were made to completelyclose the valve gate member of the valve, and too much torque would'be placed on the valve gate member in an effort to make a full seal.

text: When the valve is open, blood flows freely through the opening from the right atrium into the right ventricle.
text: When the valve is open (Figure 7-5, view B), the fluid flows through the space between the edge of the disc and the seat.
text: Since the fluid flow is equal on all sides of the center of support when the valve is open, there is no unbalanced pressure on the disc that would cause uneven wear.
text: Another reason for not leaving globe valves in the fully open position is that it is sometimes difficult to determine if the valve is open or closed.
text: Unlike a ball valve or valves with a rising stem, it is not easy to tell from examining the handle position whether the valve is open or closed.
text: The entire flow channel is a straight-through passage when the valve is fully open, and the pressure loss of medium running is minimum.
text: when the lever is aligned to the pipe, the valve is open; when it is perpendicular to the pipe, the valve is closed;
text: when it is any other position, the valve is partly open (or partly closed) and is modulating the flow.
text: Assessing the number of cusps is done in systole, because the valve is open and because in the closed position raphes can be misinterpreted.
text: When the valve is open, blood freely flows upward towards the heart and when the valves are closed, blood cannot flow back towards the legs.
text: When the facility with the slide closes for the night, the check valve stops the flow of water through the pipe; when the facility reopens for the next day, the valve is opened and the flow restarts, making the slide ready for use again.
text: The valve may also be opened incrementally to throttle flow.
text: For a rising stem valve, the stem will rise above the actuator as the valve is opened.
text: If the valve is opened the pressure has to decrease enormously before the valve closes and also the outlet pressure of the valve can easily keep the valve open.
text: After a valve is fully opened, the handwheel or actuating handle should be turned toward the closed position approximately one-half turn.
text: In addition, with this structure, when the valve is opened, at least one portion of the valve is forcibly opened by the valve opening member.
text: Accordingly, when the fuel level in the fuel tank is lowered even by only a small amount after the valve is opened, the float moves downward due to its own weight, and the valve opening member, which moves downward together with the float, strongly presses the at least one portion of the valve.
text: Therefore, even if the pressure in the fuel tank is high, the valve can be opened easily.
text: If the valve having an inappropriate thickness is used, the portion, which is pressed by the valve opening member when the valve is opened, is bent downward, and the valve contacts the valve seat with the portion bent downward when the valve is closed next time.
text: Alternatively, if load is repeatedly applied to a portion of the valve by the valve opening member each time the valve is opened, the restoring force of the portion that receives the load is reduced, and the valve contacts the valve seat with the portion bent downward.
text: In addition, with this structure, when the valve is opened, at least one portion of the valve is forcibly opened by the valve opening member.
