The types of stainless steel gate valves can be divided into wedge gate valve and parallel gate valve according to the sealing surface configuration. Wedge gate valve can also be divided into single gate pole type, double gate plate type, and elastic gate plate type; Parallel gate valves can be divided into single gate and double gate types.
According to the thread position of the valve stem, it can be divided into two types: rising stem gate valve and non rising stem gate valve. This type of valve should generally be installed horizontally in pipelines.
When opening the valve, when the lifting height of the gate is equal to 1:1 times the valve diameter, the fluid channel is completely unobstructed, but this position cannot be monitored during operation.
In actual use, the vertex of the valve stem is used as the mark, that is, the position that cannot be opened, as its fully open position. To consider the phenomenon of lockup due to temperature changes, it is usually done by turning back 1/2-1 turn at the top position as the fully open valve position. Therefore, the fully open position of the valve is determined by the position (i.e. stroke) of the gate.
Some gate valves have a stem nut located on the gate, and the handwheel rotates to drive the stem to rotate, causing the gate to lift. This type of valve is called a rotary stem gate valve or a non rising stem gate valve.
