Abstract:
A hydraulic control valve system comprising:a plurality of control valves, at least one of the valves including: a valve body, the body having a function port, a supply port to allow for the supply of a fluid to the function port, and a vent port to allow fluid to vent from the function port; a gate assembly including a gate, a seal assembly including a seal carrier slidably mounted within the gate, a shear seal to selectively direct hydraulic pressure, to and from, a subsea function by selectively alternating between a vent open-supply blocked position and a vent closed-supply unblocked position, a roller bearing assembly including a roller bearing engagement plate and an array of roller bearings interfaced with the roller bearing engagement plate and an actuation assembly for slidably moving the seal assembly; a removable hydraulic mounting module, including the plurality of control valves, an input-output module to interface the module to the actuation assembly, and a module housing; and a mounting assembly including a valve connector for connecting the valve to a mounting module, and an engagement assembly, the engagement assembly connecting the module to a fixed base having a function coupler, compensating for a separation force generated by supply pressure between the valve and the function coupler.
