Manual Non Rising Stem Gate Valve with Soft Seat High-Temperature & Corrosion Resistant
Non Rising Stem Gate Valve is a type of gate valve designed with a non rising stem, usually made of cast iron. It is a valve with a wedge-shaped disk, which is designed for the control of liquids and gas. It is mainly used in oil, gas, water, and other pipeline systems.
The face to face dimension of Non Rising Stem Gate Valve is in accordance with ASME B16.10, and it is tested according to API 598. The design standard is either API 600 or API 6D. It is operated by manual, gearbox, electric, and pneumatic system.
Non Rising Stem Gate Valve has several advantages, including excellent sealing performance, reliable operation, and long service life. It is widely used in oil, gas, water, and other pipeline system.
Non-rising stem gate valves have several distinctive features that make them suitable for specific applications. Here are some key features of non-rising stem gate valves:
1. Stem Operation: In non-rising stem gate valves, the stem does not move up or down as the valve is operated. Instead, it rotates within the valve body. This design helps to conserve space and make the valve suitable for installations with limited vertical clearance.
2. Space Efficiency: The non-rising stem design allows for a more compact valve assembly since it eliminates the need for a long stem that extends above the valve. This makes non-rising stem gate valves ideal for applications where space is limited or where vertical clearance is restricted.
3. Maintenance Convenience: Non-rising stem gate valves are relatively easier to maintain compared to rising stem gate valves. The stem does not extend above the valve, which means there is no need for a bonnet and gland arrangement. This simplifies inspection, lubrication, and packing replacement tasks.
4. Protection Against Contaminants: The non-rising stem design helps to protect the stem threads from potential damage caused by external contaminants, such as dirt, dust, or chemicals. This feature enhances the durability and longevity of the valve by minimizing the risk of stem jamming or seizing.
5. Suitable for Underground Applications: Non-rising stem gate valves are commonly used in underground installations, such as water distribution systems. Their compact design and protection against contaminants make them well-suited for buried applications where accessibility is limited.
6. Reliable Flow Control: Like other gate valves, non-rising stem gate valves offer reliable flow control capabilities. The fully open or fully closed position of the gate is achieved by rotating the stem, allowing for efficient and precise throttling of fluid or gas flow.

What is a non-rising stem gate valve?
A non-rising stem gate valve is a type of valve where the stem does not move up or down during operation. Instead, it rotates within the valve body to control the flow of fluid or gas.
How does a non-rising stem gate valve work?
In a non-rising stem gate valve, the valve gate or disc is connected to the stem, which rotates to open or close the valve. As the stem rotates, the gate moves perpendicular to the flow direction, allowing or blocking the fluid or gas flow.
What are the advantages of a non-rising stem gate valve over a rising stem gate valve?
Non-rising stem gate valves offer space efficiency, making them suitable for installations with limited vertical clearance. They are also easier to maintain since there is no need for a bonnet and gland arrangement. Additionally, they provide protection against contaminants and are commonly used in underground applications.
Are non-rising stem gate valves suitable for all applications?
Non-rising stem gate valves have specific applications where their features are beneficial, such as in plumbing systems, irrigation systems, underground installations, or where space is limited. However, they may not be suitable for all scenarios, so it’s essential to consider factors like pressure, temperature, and media type before selecting the valve type.
Can non-rising stem gate valves be repaired if they malfunction?
Yes, non-rising stem gate valves can be repaired if they develop any issues. The specific repair process may depend on the nature of the problem, but typically, it involves disassembling the valve, inspecting the components, and replacing or repairing any faulty parts.
How should I maintain a non-rising stem gate valve?
Maintenance requirements for non-rising stem gate valves are relatively straightforward. Regular inspection and lubrication of the stem and internal components are recommended. Additionally, if the valve develops any leaks or fails to operate correctly, it may require packing replacement or repairs by a qualified technician.
