Stainless steel plug valve affects a well within an opening or closing apparatus. The featured part of the valve is the rotating plug valve body with a through-hole, that runs vertically on the axis of the pipeline. The plug valve is activated by the valve stem so as to attaining the shutting-off performance.

In fact, the plug valve has been developed and applied to many different industries for a long time. With the very simple but streamlined structure, immediate functioning and low fluid immunity, this kind of valve has been occupying high recognition. The entire body of the valve, which is largely cone (air as well), cooperates with the tapered surface of the valve seat so as to form excellent sealing surfaces.

The materials such as the cast iron, cast iron, stainless steel, chrome-molybdenum steel, or brass are usually applied to the creation of the valve body. The adoption of the Wã$F or F for the produce of the sealing surface significantly increases the variety and performance of the valve. Besides, many efforts have been done to enhance the sealing and service life. As an instance, the specially manufactured grease lubricant is hauled in the top of the body into the area between the hole and the body. Such does help form movies to decrease the friction.

At this moment, the plug valve can be linked from the flanged, welded, or clamped connection. Along with the worm gear can be utilized to drive the valve. According to the channel, the valve can be classified into the straight-through type, three-way type, and four-way kind. Regardless of what, the valve itself is currently readily available for the control of this oil, oil, gas, natural gas, or some acids, and so on. So as to optimize the performance, it is necessary to be cautious in regards to the installation and regular maintenance. And it needs to be noted that the plug valve is not allowed to be utilized for regulating the stream.
