Stainless Steel Concealed Soft Seal Flange Gate Valve

As a key shutoff device in the pipeline system, the stainless steel concealed soft seal flange gate valve produced by our Tanggu Shengshi Huagong plays an important role in various fluid transportation scenarios. It accurately controls the flow and shutoff of the medium in the pipeline by raising and lowering the gate plate to ensure the stability and safety of the system operation. The valve is made of high-quality stainless steel and has excellent corrosion resistance. It can work stably for a long time in a variety of complex media environments, significantly extending the service life of the valve and reducing maintenance costs.

Product Description

The concealed stem design of our stainless steel concealed stem soft seal flange gate valve is a major feature. The operating handle of the gate valve is hidden in the valve body, which not only makes the valve look simpler and more beautiful, but also effectively reduces the risk of damage caused by accidental collisions, and improves the reliability of the valve in actual use. At the same time, the soft seal design is a core advantage. It uses soft materials such as rubber with good elasticity as sealing elements. Compared with traditional metal-to-metal seals, it can provide a tighter closing effect, greatly improve the sealing performance of the valve, effectively prevent medium leakage, and meet the application scenarios with extremely high sealing requirements. In addition, the flange connection method makes its connection with the pipeline more stable, suitable for pipeline systems of various pressure levels and pipe diameters, and is relatively convenient to install and disassemble, which is convenient for later maintenance and replacement.
