Surface safety valve (SSV) is mainly used in the station of the petroleum and natural gas, wellhead and ground process, or other devices etc. When the downstream pipeline occurs tube explosion, leakage, blockage and has lead to the well site appears the phenomenon of the over pressure or under voltage, the safety valve can be automatically shut down. Therefore, the ground safety valve can effectively prevent the danger expansion, to provide a strong guarantee for the rescue work of the oil and gas production units. SSV requires hydraulic force (2500-6000 psi), usually provided by emergency shutdown control panel (ESD Panel) Emergency Shutdown (ESD) Console is a particularly important component of surface well test system, as ESD console supplies hydraulic force to emergency shutdown valves to close flow line instantly if emergency like high pressure or high temperature occurs during well testing and production.
