A primary function of an oil and gas wellhead is to provide pressure seal or shut-in point between the casing/tubing and surface piping/facilities, among others.

The various types of valves and actuators of the Xmas tree have to be in the best operational state to ensure they are working properly and seamlessly for efficient productivity.

Reliability and ease of maintenance is, therefore, a critical property of any wellhead.
