text: The ball valve below is in the open position.
text: As you can see, the handle never goes up and down as the gate opens and lowers; for this reason, it’s impossible to know if a gate valve is in the open or closed position just by looking at it.
text: The valve structure of claim 1 wherein said motor runs in a single direction and wherein said second means further comprises a normally closed switch operatively connected to said motor, switch-opening means connected to said actuating shaft for opening said switch when said valve is in said open position, said switch being electrically isolated from said first means, and brake means operatively connected to said motor for preventing said driven shaft from moving when said motor is not running, the engagement of said clutch while said brake means is operated holding said valve in said open position.
text: When the valve is in the open/closed position, the pressure is always acting upon the bottom of the stem, trying to push the stem up.
text: (This is the normal basic position of a 3/2 way normally closed valve.)
text: As you can see, the handle never goes up and down as the gate opens and lowers; for this reason, it’s impossible to know if a gate valve is in the open or closed position just by looking at it.
text: Master valves are normally in the fully open position and are never opened or closed when the well is flowing (except in an emergency) to prevent erosion of the valve sealing surfaces.
text: In service, these valves are either in fully open or fully closed position.
text: As the valve 38 is moving from the closed position to the open position, the arm moves from the position illustrated in solid lines in FIGS.
text: The gear reduction mechanism 58 does not allow the shaft 67 to rotate in a direction opposite to the direction of the arrow 169; thus, so long as the clutch 54 i engaged, the valve 38 is held in the open position abovementioned.
text: So long as the switch 118 remains closed the solenoid 56 remains activated and the valve 38 remains in the open position.
text: Unless this is done, the valve is likely to seize in the open position, making it difficult, if not impossible, to close the valve.
text: For example, a fill valve such as valve 102 preferably includes a locking mechanism that allows the valve to be locked in an open position.
text: When the valve is in a fully closed or fully open position, each seat seals off the process medium independently at the same time between the up/downstream and body cavity; it allows bleeding of the cavity pressure through a drain or vent valve.
text: A valve unit as defined in claim 1, including a centrally apertured valve retainer member below said valve seat member having openings for passage of urine therethrough when the valve is in open position, said movable valve member being located between said valve seat member and said valve retainer member.
text: A valve unit as defined in claim 7, including a centrally apertured valve retainer member below said valve seat member having openings for passage of uring therethrough when the valve is in open position, said movable valve member being located between said valve seat member and said valve retainer member.
text: For example, a fill valve such as valve 102 preferably includes a locking mechanism that allows the valve to be locked in an open position.
text: Self-closing stop valve means a stop valve held in the closed position by means of self-stored energy, that opens only by application of an external force and that closes when the external force is removed.
text: As soon as the electric current is absent, the valve switches back into basic position (1 closed, open from 2 to 3).
text: When the valve is in the closed position and opening is commenced the small end of the 'v' is opened first allowing stable flow control during this stage.
text: In service, these valves are either in fully open or fully closed position.
text: The valve is opened by a non-reversible motor, held in an open position by a brake and clutch mechanism, closed by releasing the clutch mechanism allowing the valve to move into a closed position in accordance with the suction of the system, and held in a closed position by the suction of the system.

text: Thus, when the rod is leftwardly, as shown in Figure 4, and pressure is introduced through port 17, the valve 76 remains in closed position because of the larger effective pressure surface on its right side.
text: Further, the arrangement of the valve seat in the casing eliminates bottoming" of the valve gate member preliminarily of the seating of the remainder of the gate member, and consequently, a sufficient minimum torque may be used to provide for complete stoppage of flow of fluid when the valve is in the closed position.
