Embodiments of the present disclosure relate to a choke valve that includes a choke body, a choke trim disposed in the choke body, where the choke trim is configured to adjust a cross-sectional area of a flow path in the choke body to adjust a fluid flow through the choke valve, a needle of the choke trim disposed in the flow path of the fluid flow, where the needle includes a first portion having a superhard material, a seat of the choke trim, where the needle is configured to move along an axis extending through an opening of the seat to adjust the fluid flow through the choke valve.

A disc for a multiple orifice valve includes a disc body and a disc orifice extending through the disc body. A disc surface of the disc body includes a recessed portion and a raised portion that at least partially circumferentially surrounds the recessed portion. The recessed portion is configured not to contact an opposed disc when the disc is assembled within a housing of the multiple orifice valve, and the raised portion is configured to contact the opposed disc when the disc is assembled within the housing of the multiple orifice valve.

A system includes a choke valve, an actuator configured to adjust a position of the choke valve, a variable frequency drive configured to adjust a speed at which the actuator adjusts the position of the choke valve, and a controller configured to receive first feedback indicative of a fluid pressure upstream of the choke valve, compare the first feedback to a first predetermined pressure range, and instruct the variable frequency drive to send electricity to the actuator at a first frequency when the first feedback is outside of the first predetermined pressure range, where the variable frequency drive is configured to control a speed and a direction of the actuator such that the actuator adjusts the position of the choke valve to a first position at a first speed, and where the first speed is based at least on a difference between the first feedback and the first predetermined pressure range.
