Subsea double expanding gate valves are designed according to API6DSS, API6A, API17D with the addition of customer requirements when present. The valves do not rely on lubricant or grease to assist sealing between the gates and seats. Metal-to-metal sealing is used between the gate and seat and between the seat and body. Metal-to-metal sealing is also provided between body-to-bonnet. The Subsea double expanding gate valves are actuated by hydraulic actuator or gearbox as requested.
