AWWA C515 rising stem rubber wedge gate valve

Product profile :

Elastic seat seal gale valve is also called the lifting stem gate valve (also known as the stem gate valve). Usually there are trapezoidal threads on the lifting lever, which convert the rotary motion into linear motion through the nut at the top of the vale and the guide grooves in the valve body, lie. the operating torque into the operating thrust. When the valve is opened, the hid passage is completely clear when the gale is lifted at a height equal to 1:1 times the valve diameter, but this position cannot be monitored during operation. In practice, the vertex of the valve stem is used as a sign, that is, the position of the open, as is 4 open position. In order to consider the temperature changes appear lock phenomenon, usually open to the apex position, and then back to 1/2-1 turn, as the position of the full open valve. Therefore, the fully open position of the valve is determined by the position of the gate (i.e., stroke >).

Features :

In addition to the advantages of the elastic seat-seal gate valve, it can also display the opening degree of the valve directly. It is quickly and reliably opened and closed, and has obvious opening and closing degree.
