Wellhead Valve Hydraulic Closure Unit

When working on projects in the oil and gas industry, we understand that safety and efficiency are the keys to successful projects. Wellhead Valves must be operated carefully when being closed. Some valve types have a shear pin between the handle and stem, which will protect the valve’s internal components if excessive force is applied. The master valve should not be used to close in a flowing well, except in an emergency. The swab or wing valves are typically used. Every time the gates of the valve shut in a flowing well, the increase in velocity of the well fluids during the closing action can cause wear across the seal faces. This means that valves can get harder to manually seal over time and become more susceptible to valve failure. 

We were recently approached by one of our customers to build a hydraulic-powered closure unit for their new line of surface test trees. They needed a system to automate the valve closing process, instead of requiring hand tools, to help eliminate uncertainty with regards to closing the master valve in the tree.  Our team of engineers worked without clients team to design the following systems.
