Non-Rising Stem Gate Valves (NRS); Non-Rising Shaft Gate Valves are one of the valve types designed for purposes such as cutting and controlling underground water lines. In this type of valves, the shafts are connected to the slider by means of teeth and move within the system. It is seen that the valve occupies less vertical space as the shaft remains inside the body.
It is possible to state that it has a wide usage area as it is suitable for both aboveground and underground installation. Pressure loss is much lower than many valves. For this reason, it is a known fact that it has many advantages. They are produced in diameters of 50 mm-250 mm.
Non-Rising Shaft Gate Valves used in main lines and hydrant systems are a remarkable product with their innovative features. It is seen that it is used for purposes such as cutting and controlling the fluid in the system. They can be used comfortably with the post indicators whose open / closed position is visible.
Non-rising shafts are connected to the bolt in the system with teeth. Due to this feature, it is separated from the rising spindle gate valves. Although this type of valve is similar to butterfly valves, they differ from butterfly valves in terms of various features. Non-rising stem gate valves differ from butterfly valves in that they create less hydraulic loss. However, the general features of these valves are very similar to each other.
Non-Rising Shaft Gate Valves are a type of valve that controls or cuts the flow in the system thanks to the slide and the shaft. Such valves, which are used in many areas, incorporate innovative and technological features. Non-rising stem gate valves, which are frequently preferred in the industrial field, are also used in areas such as the chemical industry and paper mills.
Thanks to its sealing mechanism, it allows the system in which it is located to work effectively. The fact that it can be used both underground and above ground is among its advantages. It is also known that there is no need for a valve chamber when used underground.
The basic working principles of gate valves are quite similar to each other. The flap, called the slider, moves thanks to the screw shaft, allowing the fluid in the system or the fluid is cut off. Although the basic working principle is like this, the different mechanisms in the gate valves have led to the emergence of different types of gate valves.
Non-rising stem gate valves with non-rising stem gate valves have a wide usage area. They can be used comfortably as they do not require maintenance. In addition, its long service life makes it possible to use it for a long time without any problems. The very low pressure loss can be considered among the advantages of this type of valve.
Non-Rising Shaft Gate Valves are a type of valve preferred in many areas. This type of valve, which is included in the gate valves, has innovative features. It has a non-rising shaft and the flow in the system is controlled. It is possible to state that they are generally preferred in main lines and hydrant systems.
The usage areas of the non-rising stem gate valves, which are used to cut and control underground water lines, are not limited to this. It can be used easily both underground and above ground. On / off status can be seen when used with post indicators. In addition, it is known that there is no need for a valve room when used with post indicators underground.
These types of valves, which protect the system they are in with their innovative features and technological infrastructure, draw attention with their features that ensure long-term use.
Product description
They are valves used to cut and control underground water lines in main lines and hydrant systems. It can be used with post indicators whose on/off position can be seen. If it is used together with the post indicator underground, there is no need for a valve room.
Production Dimensions: 2” (50 mm) – 10” (250 mm)
