An apparatus for controlling a fluid flow may include a flow channel, a housing, a flow restrictor, and a housing adjustment member. The flow channel defines a fluid pathway for the fluid flow. The fluid pathway includes an inlet and an exit. The housing surrounds the flow channel. The housing comprises an exterior surface defining a first threaded portion. The flow restrictor is located within the housing and proximate the exit. The housing adjustment member includes a second threaded portion in contact with the first threaded portion. Embodiments may include a method for controlling a fluid flow. The method comprises: causing the fluid flow to pass through a flow channel having an inlet and an exit; restricting, via a flow restrictor, the fluid flow, the flow restrictor located proximate the exit; and adjusting a position of the flow restrictor to further restrict or unrestrict the fluid flow.
