Real product show
Non-rising Stem Gate Valve is a type of gate valve commonly used in wastewater systems. It is made of ductile iron, which provides strength and durability. This gate valve is designed to control the flow of wastewater by raising or lowering a gate mechanism. With its non-rising stem feature, the valve operates vertically without extending out of the valve body, making it suitable for tight spaces or underground installations. These wastewater gate valves are known for their reliable performance and ability to handle the demands of sewage and wastewater applications.

FAQ
Q: What is a non-rising stem gate valve?
A: A non-rising stem gate valve is a type of valve that uses a threaded stem rather than a rising stem to control the flow of fluid through a pipe. The stem does not move up or down as the valve is opened or closed.
Q: How does a non-rising stem gate valve work?
A: In a non-rising stem gate valve, the threaded stem is attached to a gate disc inside the valve body. When the stem is turned clockwise, the gate disc is lowered, allowing fluid to flow through the valve. When the stem is turned counterclockwise, the gate disc is raised, closing off the flow of fluid.
Q: What are the advantages of using a non-rising stem gate valve?
A: Non-rising stem gate valves have several advantages. Firstly, they require less vertical space compared to rising stem gate valves, making them suitable for installations with limited overhead clearance. Secondly, they are less prone to damage in high vibrations or tight spaces since the stem does not extend above the valve body. Additionally, non-rising stem gate valves are easier to install and maintain due to their compact design.
Q: When should I use a non-rising stem gate valve?
A: Non-rising stem gate valves are commonly used in applications where vertical space is limited, such as underground pipelines, tight spaces, or installations with low overhead clearance. They are also preferred in areas with high vibrations where a rising stem could be prone to damage.
Q: Are there any limitations to using non-rising stem gate valves?
A: While non-rising stem gate valves have advantages, they also have limitations. One limitation is that the position of the gate disc cannot be visually determined without additional indicators since the stem does not move visibly. Additionally, non-rising stem gate valves may require more torque to operate compared to rising stem gate valves, depending on the design.
Q: What materials are non-rising stem gate valves made of?
A: Non-rising stem gate valves can be made of various materials depending on the application requirements. Common materials include stainless steel, carbon steel, cast iron, bronze, and ductile iron. The choice of material depends on factors such as the type of fluid, temperature, and pressure.
Q: How should I maintain a non-rising stem gate valve?
A: Regular maintenance of a non-rising stem gate valve is essential to ensure its reliable operation. This may include periodic lubrication of the stem threads, inspection of the gate disc and sealing surfaces for wear or damage, and addressing any leaks or abnormal valve performance promptly. It is also important to follow the manufacturer's guidelines and recommendations for maintenance procedures and intervals.
Q: Can non-rising stem gate valves be used for regulating flow?
A: Non-rising stem gate valves are primarily designed for on-off service, meaning they are used to either fully open or fully close the flow of fluid. They are not typically used for precise flow regulation due to the limited visibility of the gate disc position and the potential for increased torque requirements. For flow regulation, other valve types such as globe valves or butterfly valves are often preferred.
