NRS gate valve is a type of valve that is widely used in various industries such as chemical, pharmaceutical, gold, petroleum, sewage, water, construction, ship, light textile, energy system, and more. It is a popular choice as a regulating and intercepting device in medium pipelines.
One of the key advantages of NRS gate valve is that it is driven by the stem rotating at a fixed point to lift the valve flap upward and downward to complete the opening and closing process. Unlike other gate valves, the stem of NRS gate valve is concealed, making it a more streamlined and compact option for installations with limited space.
| NRS Gate Valve Material | Standard | Actuated Mode | Sealing method | Applications and Uses |
|---|---|---|---|---|
| cast iron, cast steel | API, DIN, JIS, KS, EN, BS, EAC, NF | manual operation, electric actuator, actuated of water/air/oil | Hard seal, soft seal, single-sided seal, double-sided seal, etc. | NRS gate valve is compact and lightweight, saving the space occupied during installation. |
Advantages of NRS Gate Valve
NRS (Non-Rising Stem) gate valves have several advantages that make them a popular choice in various industries. Here are some of the key advantages of NRS gate valves:
- Compact Design: The non-rising stem design of NRS gate valves allows for a more compact overall size, making them ideal for applications where space is limited.
- Cost-Effective: NRS gate valves are generally more cost-effective than other types of gate valves due to their simple design and construction.
- Easy to Operate: NRS gate valves are easy to operate, with a simple turning motion of the valve handle or hand wheel to open or close the valve.
- Low Maintenance: The concealed stem design of NRS gate valves makes them less prone to damage or wear, resulting in low maintenance requirements and reduced downtime.
- Versatile Applications: NRS gate valves can be used in a wide range of applications, including water treatment, chemical processing, power generation, and oil and gas industries.
