SELF CONTAINED SSV

The Self Contained Surface Safety Valve (SCSSV)uses hydraulic fluid pressure generated by a manual hand pump. Its major use is to protect facilities from the effects of pipeline failure and abnormal conditions. Unlike DLPO systems, line pressure is not used to operate the SCSSV system. The Surface Safety Valve system is designed for remote shutdown of wellheads or flowlines that encounter a high or low pressure condition. It is operated by high and low pressure pilots sensing the flow line pressure, which enters the system through a tap in the upstream flange of the valve. The optional ESD emergency shutdown system can be used to enable field operators to shut down the flow line at any desired time during production, testing or maintenance operations. Available in 2.1/16” through 7 1/16” nominal valve sizes with various pressure ratings.
