JXAF Type Surface Hydraulic Controlling Subsurface Safety Valve is a balanced safety valve connecting with pipeline.

Product Description   JXAF Type Surface Hydraulic Controlling Subsurface Safety Valve is a balanced safety valve connecting with pipeline.It mainly consists of piston assembly,pressure spring,butterfly valve assembly,fluid controled line and so on.It is designed as First Class(standard working condition)  and Class 3S(avoiding cracking caused by sulfur and stress) of oil well's  working condition from API.The safety valve in subsurface is connected by fluid controled line and  the hanger of X-mas tree.Controlling its switch through operating the hydraulic controled board on surface.It is maily used to cut off the fluid in pipeline which abnormal things happened.

     The subsurface safety valve is open when the well is in production,and when closing well is needed,the safety valve can be turned off after draining off the fluid controled line.In order to prevent the fluid in pipeline from flowing.
