Extension Stem Ball Valve

                                              Extension Stem Ball Valve

When will you use extension stem ball valve:

The elongated stem ball valve increases the position between the horizontal hole surface of the valve and the handle, so as to meet the requirements of different use conditions. The extension rod ball valve generally adopts flange connection, but also can adopt butt welding connection. The valve stem of the ball valve is lengthened. For example, the general ball valve position is far from the operating position, and the connecting rod can be processed, which is equivalent to the valve stem. However, not all valves have to extend the stem. If you want to improve the original ball valve parts (valve stem), you must know the working conditions of the ball valve to lengthen it. The stem of the ball valve after lengthening should be prevented from bending. The height of  ball valve is generally selected according to the actual needs of customers, which can meet the requirements of different operating heights, and can increase the protection position of the valve, which improves the performance of the ball valve.
