Subsea rotary gate valves are designed according to API6A and API17D with the addition of customer requirements when present. The valves do not rely on lubricant or grease to assist sealing between the gate and seat. Metal-to-metal sealing is used between the gate and seat. Metal-to-metal sealing is also provided between body-to-bonnet. The Subsea rotary valves are actuated by hydraulic actuator or direct manual ROV interface.
