Product Details

NSV Non-rising stem gate valves it is usually suitable for tight places where there is not enough room for the stem to raise, for example, places with underground pipes. The non-rising stem gate valve is fully open when the handle is rotated as far as possible to the left and fully closed when the handle is rotated as far as possible to the right. In both cases the handle is flush with the pipe because the mechanism inside the pipe opens and closes the valve without raising the stem. Another advantage to the non-rising stem gate valve is that it is easier to padlock. With the rising stem gate valve, two different size padlocks could be needed to lock the valve open and closed. With the non-rising gate valve one padlock is enough. But the disadvantage of a non rising stem valve is the fact that the screw threads that lift the gate are exposed to the fluid being controlled by the valve. This can cause problems if the fluid tends to foul the threads, so non rising stem valves are usually only used on clean liquids and gases.
