Reliable Non-Rising Stem Valve for Commercial and Residential Use
The non-rising stem design of the flanged non-rising stem sealed gate valve reduces the risk of leakage in many ways. First, the non-rising stem design prevents the valve stem from being exposed during the opening or closing process, thereby reducing direct external influences on the valve stem, such as corrosion and impact, which helps to extend the service life of the valve and reduce the risk of leakage. Secondly, the use of high-quality sealing materials and soft sealing design ensures that there is no leakage when the valve is closed.
In addition, metal seals or elastic seals are used, which have good sealing performance and can effectively prevent medium leakage. The double sealing design (bellows + packing) further improves the sealing performance. Even if the bellows fails, the valve stem packing can avoid leakage. API 6A high-pound grade concealed stem flat gate valve adopts the principle of preload and sealing pressure ratio to ensure good sealing effect under different pressures.
In flange concealed stem sealing gate valves, the application of high-strength copper alloy and special rubber has a significant impact on the sealing performance. High-strength copper alloys are commonly used in the manufacture of valve bodies and sealing surfaces. The wedge-type single-gate gate valve with a sealing surface of surfacing copper alloy is widely used in drainage, gas, electric power, petroleum, textile, metallurgy, chemical industry, urban construction and other industries.
Flange concealed stem sealed gate valves are also widely used in the petroleum and chemical industries. For example, imported concealed stem soft-sealed gate valves are widely used in many fields such as petroleum, chemical, food, and medicine. This valve adopts high-tech products and uses the overall rubber coating of the gate to produce deformation compensation to achieve a good sealing effect, overcoming the problems of poor sealing, water leakage, and rust of general gate valves.
