DIN3352 F4 NRS Flanged Soft Seal Gate Valve

Excellent Sealing Performance: Usually, special soft-sealing materials such as EPDM rubber are adopted, which are closely combined with the gate plate through the vulcanization process. Taking advantage of the good elasticity and reset characteristics of rubber, it can achieve reliable sealing and effectively prevent the leakage of media.

Non-rising Stem Design: The valve stem is located inside the valve body and does not expose when the gate plate moves up and down. This design makes the appearance of the valve simpler. At the same time, the valve stem is not easily affected by the external environment, reducing corrosion and wear, prolonging the service life, and also reducing the operational risks caused by the exposed valve stem.

Flanged Connection: With the flanged connection method in accordance with the DIN3352 F5 standard, it has the characteristics of high connection strength and good stability. It is convenient for installation and disassembly and can be reliably connected with various pipelines and equipment that meet the corresponding standards, ensuring the sealing performance and overall performance of the system.

Reliable Safety Design: For example, it adopts a triple-safety valve stem sealing system, together with a high-strength valve stem and comprehensive corrosion protection measures, ensuring that the valve can operate stably and safely under various working conditions and providing unparalleled reliability.

Good Versatility: It can be applied to a variety of media, including water, oil, gas, and some corrosive chemical media, etc. It can be widely used in different industrial fields, such as pipeline systems in industries like water supply and drainage, chemical engineering, petroleum, metallurgy, construction, etc., for cutting off or connecting media, with strong versatility and adaptability.
