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.

Linear grease and hydraulic valve for fracking system maintenance

A hydraulic control system for blowout preventers systems, frack valves and chokes, and related wellhead and control equipment used in oil and gas well drilling operations. The hydraulic control system can include one or more hydraulic control valves or pressure regulators including an internal, linear slider and pairs of seal rings. Lapped and polished surfaces of the seal rings and sliders can form a dynamic metal-to-metal seal within the hydraulic control valves or pressure regulators.
