Product Features and Advantages
Excellent Sealing Performance: It uses soft sealing materials such as rubber and polytetrafluoroethylene, which can closely fit with the gate plate and the valve body, effectively preventing the leakage of media. With outstanding sealing performance, it can meet various working conditions with high sealing requirements.
Non-rising Stem Design: The valve stem is located inside the valve body and will not be exposed as the gate plate moves up and down. This not only makes the appearance of the valve more concise and aesthetically pleasing but also prevents the valve stem from being directly exposed to the external environment, reducing the possibility of corrosion and wear, prolonging the service life of the valve stem, and also minimizing the operational risks caused by the exposed valve stem.
Flanged Connection: The flanged connection method is in accordance with the EN1092-2 standard or meets the requirements of customers. It features high connection strength and good stability. It is convenient for installation and disassembly and can be reliably connected to various pipelines and equipment that meet the corresponding standards, ensuring the sealing performance and overall performance of the system.
Simple Operation: The valve is operated by rotating the handwheel to drive the valve stem to rotate, and then controlling the lifting of the gate plate to achieve the opening and closing of the valve. This operation method is simple and intuitive, with a relatively small operating force, making it convenient for operators to carry out daily opening and closing control, and it is suitable for various different working environments.
Wide Applicability: It can be applied to a variety of media, including water, oil, gas, and some corrosive chemical media, etc. At the same time, it can be used in different industrial fields, such as pipeline systems in industries like water supply and drainage systems, chemical engineering, petroleum, metallurgy, construction, etc., for cutting off or connecting the media, with strong versatility and adaptability.
