A non-rising stem resilient seated gate valve (NRSSGV) is a type of gate valve that is designed with a rubber seat that provides a tight seal and a non-rising stem that is not visible above the valve body when the valve is closed.
Here are some key features of the NRSSGV:
Rubber seat: The NRSSGV has a rubber seat that provides a tight seal and ensures reliable shutoff. The rubber seat is resilient and can conform to irregularities in the pipeline, which helps to prevent leakage.
Non-rising stem: The NRSSGV has a non-rising stem that is not visible above the valve body when the valve is closed. This design helps to prevent damage to the stem and makes it easier to install the valve in areas with limited vertical space.
Easy operation: The NRSSGV is easy to operate, as it only requires a quarter-turn of the handle to open or close the valve. This makes it a good choice for applications where frequent operation is required.
Corrosion resistance: The NRSSGV is designed to resist corrosion, which makes it suitable for use in a wide range of applications, including water treatment, sewage treatment, and industrial processes.
Low maintenance: The NRSSGV is relatively low maintenance compared to other types of gate valves. Its rubber seat is less prone to wear and damage than metal seats, and its non-rising stem design reduces the risk of damage to the stem or the valve components.
Overall, the NRSSGV provides a reliable and efficient option for applications where tight shutoff, corrosion resistance, and low maintenance are important considerations. Its rubber seat and non-rising stem design contribute to reliable performance and ease of operation, non rising stem resilient seated gate valve while its corrosion resistance makes it suitable for use in a wide range of industries and applications.
Compared to other types of gate valves, the NRSSGV is generally more cost-effective due to its design and construction.
Here are some factors that contribute to the NRSSGV's lower cost:
Rubber seat: The rubber seat of the NRSSGV is less expensive than metal seats used in other types of gate valves. This makes the NRSSGV a more affordable option for applications where tight shutoff is required.
Non-rising stem: The non-rising stem design of the NRSSGV is simpler and less expensive to manufacture compared to other types of gate valves that have a rising stem. This reduces the overall cost of the valve.
Easy operation: The NRSSGV is easy to operate, as it only requires a quarter-turn of the handle to open or close the valve. This makes it a more affordable option for applications where frequent operation is required, as it reduces the need for additional labor or equipment.
Low maintenance: The NRSSGV is relatively low maintenance compared to other types of gate valves. Its rubber seat is less prone to wear and damage than metal seats, which reduces the need for replacement and maintenance.
Overall, the NRSSGV is a more cost-effective option compared to other types of gate valves due to its simpler design and construction. However, the cost of any valve will depend on several factors such as the size, material, and operating conditions. It's important to consider all of these factors when choosing the right valve for a specific application.
