It also used for collecting the casing string and the tubing string, and sealed the annular space between every sleeve and the pipeline. It can also control the pressure of the wellhead, and regulate the wellhead device and the flow of the wellhead of oil extraction. Besides, it can used for some special work, such as fracture acidizing, water injection and testing, it can meet different working condition, and reliable sealing, work security. The valve is an important part of the wellhead equipment and the control part of the fluid transmission system. It has the functions of cut-off, regulation, diversion, overflow and pressure relief. Our company can produce valves suitable for various well conditions. Oil wellhead gate valve, as the most important equipment of oil wellhead, is used to open or cut off media flow and control the flow direction as needed.

Faults:
valve stem threads are directly eroded by medium. 

Requirement:
Install gate valve opening indicator
