    Abstract: A choke gate valve includes a housing that defines a fluid bore and a gate that includes a throttling orifice. The gate is configured to move within the housing between a throttle position in which the gate extends across the fluid bore to position the throttling orifice in the fluid bore to throttle a fluid flow through the fluid bore and an open position in which the gate does not block the fluid bore to enable a full level of the fluid flow through the fluid bore. The choke gate valve may be used as part of a choke gate valve system to transition between first fracturing operations for a first well and second fracturing operations for a second well without shut off of a pump.

    Abstract: Disclosed is a device that includes a choke valve. The choke valve may include a generally tubular throttling member having a sealing shoulder disposed in an inner volume of the throttling member, a plurality of openings configured to flow a fluid between the inner volume of the throttling member and an outer volume of the throttling member, and a flow-impeding recess disposed between the sealing should and the plurality of openings in the inner volume of the throttling member. The choke valve may also include a valve member disposed at least partially in the inner volume of the throttling member.

    Abstract: A system includes a choke valve having a fluid inlet configured to receive a fluid at a first pressure and a fluid outlet configured to output the fluid at a second pressure. The choke valve also includes a fixed component and a movable component defining a throttling orifice between the fluid inlet and the fluid outlet. Additionally, the movable component is configured to automatically move relative to the fixed component in response to a change in the first pressure to maintain a consistent percent pressure drop between the first pressure at the fluid inlet and the second pressure at the fluid outlet.

    Abstract translation: 一种系统包括具有流体入口的阻塞阀，所述流体入口构造成在第一压力下接收流体，并且流体出口配置成在第二压力下输出流体。 阻塞阀还包括固定部件和在流体入口和流体出口之间限定节流孔口的可移动部件。 另外，可移动部件构造成响应于第一压力的变化而相对于固定部件自动移动，以保持流体入口处的第一压力和流体出口处的第二压力之间的一致的百分比压降。
