The union ends API 6A mud gate valves are mainly used for drilling mud circulating system in oil field, It is used to control the flowing and stopping of mud. It is joined by trapezoid thread connection, It is quick and convenient to fix the equipment. The equipment has strong rigidity is safe and reliable, The union ends mud gate valve seat and gate are sealed by means of parallel-type Metal to Metal Sealing, The effection of sealing is good,It is convenient to open, The two ends of the valve and pipes are joined and staled with spherical movement,The movable connection of the rubber seal ring like "O" is not of high requirement about straightness of the two ends of pipes, When is is fited and its seal performance is very good.
