Specialityvalve is the dominant Rising Stem Gate Valve Manufacturer in India. The Gate valve serves to start or stop flow rather than to regulate it. A rising stem is a type of valve mechanism in which the stem of the valve rises along with the gate, disk, or globe when open. This gives a good visual indication of whether the valve is open or not because the raised stem is visible.
The valve is completely detach from the flow path in the open position, which minimizes pressure drop. But when in a totally closed position there is no flow and no pressure drop. This feature makes it an isolation application, especially in large-diameter and high-pressure lines. It has its thread external to the valve body. When the handwheel is rotate, it drives the nut within the bonnet, leading to the raising or lowering of the stem.
The location of the valve is made easy as the rising stem is always up when open and down when closed. A larger installation height is needed for this valve design relative to the non-rising design. Rising stem gate valve may feature stable handles or wheels in which the stem rises out of the center of the handle or handles when opened or which rise with the stem.
