Abstract
A fracking stack assembly coupled with a wellhead is disclosed. The fracking stack assembly can include a linear shear-flow controller configured to deliver the flow of pressurized lubricant to the fracking valve. The linear shear-flow controller can include a housing around an interior space, a supply port receiving a flow of pressurized lubricant, an outlet port; and a slide having a first end and a second end disposed within the interior space and movable along a linear axis. A first side of the slide can sealingly engage with a first sealing ring, and a second side of the slide can sealingly engage with a second sealing ring, such that the slide is slideable along the linear axis between blocked and open positions.
