Wedge Resilient Gate Valve, rising stem handwheel operation?
Rising stem gate valve rise or drop the valve bonnet through advances / retreats the hanwheel turning and the valve stem thread, bonnet connected with valve stem to open or close valve. The stem nut is on the valve cover or bracket, when openning and closing the gate, stem nut is rotated to achieve the lifting of the stem. The design of this structure is good for lubrication of valve stem,and the degree of opening and closing is obvious, so it is very popular in the market.
The transmission thread on the valve stem is outside the valve body and can be seen directly by the user. Therefore, the user can intuitively judge the opening and closing and position of the gate according to the movement direction and position of the valve stem, and the transmission thread is easy to lubricate and not corroded by fluid, but it requires a larger installation space.
