A closed-position valve disc is respectively installed on a pair of closed-position wedge-shaped sides. A closed-position guide key is respectively arranged at the middle positions of the pair of closed-position wedge-shaped sides along an axial direction. A closed-position guide groove is arranged on each closed-position valve disc along the axial direction. An open-position valve disc is respectively installed on a pair of open-position wedge-shaped sides. An open-position guide key is respectively arranged at the middle positions of the pair of open-position wedge-shaped sides along the axial direction. An open-position guide groove is arranged on each open-position valve disc along the axial direction.

摘要： A ball valve system includes a body having an upstream end and a downstream end and a ball within the body between the upstream end and the downstream end, the ball being rotatable about a vertical axis to move between a closed position and an open position. The ball valve assembly includes a stem movable in an actuation direction substantially parallel to the vertical axis, the stem including a recess at a proximal portion of the stem, a guiding member extending within the recess of the stem, the guiding member being configured to prevent rotation of the stem or cause rotation of the stem, and a lubrication port in fluid communication with the recess.

摘要： A low pressure, low operating force valve, for applications where automated valves are used, having reduced power requirements for an associated actuator. A low torque ball valve of a fixed ball valve configuration for low to medium pressure applications, such as for an electric motor actuated residential shutoff valve where pressures are typically below 100 psi, and commonly less than 60 psi, for example. The valve can be open or shut using a smaller electric motor than would be required for a conventional residential floating ball shutoff valve of a similar size. As such, the power requirements of the electric motor or other actuator are reduced allowing for the use of smaller motors, smaller power supplies and overall more efficient operation.

摘要： The valve (1) comprises a body (2) delimiting a conduit (4) and having a connection portion (6) where one end of the conduit (4) opens, the connection portion (6) being intended to be connected to the storage tank (100). In addition, said valve (1) comprises a clamping member (22) movably mounted on the connection portion (6) in order to keep the connection portion (6) attached to the storage tank (100), sealing member (10) able to rotate in the conduit (4) between a closed position in which the sealing member (10) seals the conduit (4) and an open position in which the sealing member (10) opens a passage through the conduit (4), two seats (24) interposed between the sealing member (10) and the valve body (2), and elastic return means configured to keep the seats (24) and the sealing member (10) pressed together. The conduit (4) has an angled portion (42) arranged between the connection portion (6) and the sealing member (10).

摘要： A valve device includes: a valve having a ball surface having a convex spherical shape, and a first opening opened in the ball surface to allow fluid to pass through; and a seat having an annular shape and opposing the ball surface to be in sliding contact, the seat being pressed against the ball surface, the seat having a second opening to communicate with the first opening. The seat has a sealing surface in a sliding contact with the ball surface at a valve closed time when the ball surface and the second opening overlap with each other, and a seat contact surface in a sliding contact with an opening inner wall surface or an opening end surface of the first opening at a valve opened time when the first opening and the second opening overlap with each other.

摘要： A refrigerant control valve apparatus includes a valve body accommodated inside a valve housing, the valve housing being formed with an inlet port and a discharge port. A seal mechanism includes a seal body and a biasing mechanism. The seal mechanism is provided with a first pressure receiving surface receiving pressure of the refrigerant, which acts in a direction same as a biasing direction of the biasing mechanism, and a second pressure receiving surface receiving pressure of the refrigerant, which acts in a direction opposite to the biasing direction of the biasing mechanism. The first pressure receiving surface and the second first pressure receiving surface are formed to include an equal area to each other, and the seal mechanism is accommodated within a seal accommodation space such that pressure of the refrigerant from the inlet port acts on the first pressure receiving surface and the second pressure receiving surface.
