Rising Stem Stainless Steel Gate Valve
A rising stem stainless steel gate valve is a type of valve that is commonly used in industrial and commercial piping systems. The valve is made of stainless steel, which makes it resistant to corrosion and suitable for use in harsh environments. The “rising stem” refers to the design of the valve, in which the stem of the valve rises and lowers as the valve is opened and closed. This allows for an easy visual indication of the valve’s position and makes it easy to operate. The valve is used to control the flow of liquids or gases and can be used in a variety of applications, including water treatment, chemical processing, and oil and gas production.
The working principle of a rising stem stainless steel gate valve is based on the movement of a gate or wedge-shaped disc inside the valve body. When the valve is in the closed position, the gate is positioned parallel to the flow of the liquid or gas, blocking the flow through the valve. When the valve is opened, the stem connected to the gate is rotated, raising the gate out of the way of the flow. This allows the liquid or gas to pass through the valve.
The stem of the valve is connected to a hand wheel or other actuator, which is used to rotate the stem and open or close the valve. When the hand wheel is turned clockwise, the stem is rotated, raising the gate, and opening the valve. When the hand wheel is turned counter clockwise, the stem is rotated in the opposite direction, lowering the gate, and closing the valve.
