Gate Valve Rising Stem; The gate valve is a valve with rising shaft, which shows the feature of controlling or cutting the flow by separating the zones in fire installations. Rising stem gate valves, which perform the same task as conventional butterfly type valves, may also have the feature of being electrically monitored with a monitoring switch. When the rising stem gate valve is in the fully open position, it does not affect the flow, flow rate and direction of the water in the installation. Rising stem gate valve; It is suitable for threaded, threaded or flanged connections. Although it is also used in cold and hot water installations, rising spindle gate valves are more commonly preferred in fire installations.
Gate valve with rising stem has a very critical place in the scope of ensuring or interrupting the fluid flow in the system. These valves, which enable the liquid to be followed, especially in fire installations, prevent the destruction caused by the valve being closed in case of possible fire.
Rising stem gate valves have low operating torque. With this feature, it can be used easily for a longer time. It is suitable for use between -21 and +110 degrees temperature values. It has FM approval certificate and has successfully passed international tests in terms of performance. The main advantage of the rising stem gate valve, unlike the butterfly valves, is that it provides a lower pressure loss.
The gate valve is a rising spindle, with its most general definition, a local control valve. The rising stem gate valve, which provides control of the liquid flow, is also suitable for use as a shut-off valve in water supply lines. Unlike butterfly valves, it creates less hydraulic loss. Valve body and top cover are made of stefo casting.
The rising stem gate valve, which has 100% sealing feature, has a special working principle. The spindle movement of the gate valves, which allows the liquid flow to be followed visually, indicates that the valve is in the open position. It is also possible to electrically monitor the fluid movement in the system by mounting a monitoring switch.
Gate valve with rising stem has the function of controlling whether the fire installations are working in accordance with their purpose. Although they perform a similar function with butterfly valves, rising stem gate valves are shut-off valves. Therefore, it also has the function of preventing the flow of liquid. It also offers the opportunity to electrically control whether the system is working with the help of the monitoring switch.
The most basic function of the rising stem gate valves is to prevent the damage that may occur in the fire extinguishing system. In order to prevent the liquid flow being blocked due to different reasons, control can be performed with a rising stem gate valve. Today, it has a wide range of uses, including in the industrial field.
The gate valve has a wide range of uses due to its rising spindle, cutting and liquid monitoring features. However, it plays a vital role especially in fire extinguishing systems. In fire extinguishing systems, rising stem gate valves, which provide the opportunity to control whether the system is working correctly or not, are also widely used in cold and hot water lines.
The usage areas of rising spindle gate valves can be expressed as follows:
The FM approved rising stem gate valve is suitable for flanged connections. It is specially produced for a long-term trouble-free and efficient use.
