Model Name:Ds343Y-16C DN1000 Introducing our latest product, W830 series high performance triple eccentric full metal seal butterfly . This innovative valve combines advanced sealing features with exceptional product advantages, making it a reliable and durable solution for various applications. Let's start by highlighting the sealing features of this valve. It is specifically designed to improve oxidation resistance, wear resistance, erosion resistance, and corrosion resistance of the sealing surface. This ensures safe operation even in harsh working conditions, such as handling granular media. The friction coefficient between the sealing ring and the sealing surface is greatly reduced, reducing friction and extending the service life of both the sealing ring and the valve. With these sealing features, our valve guarantees long-lasting performance, minimizing maintenance and replacement costs. Moving on to the product advantages, the structural design of the Triple-eccentric all-metal two-way hard-seal butterfly valve offers unparalleled benefits. One standout advantage is the ability to replace the valve seat and sealing ring online, saving time and resources. This feature eliminates the need to stop operations for maintenance, increasing overall efficiency. Furthermore, the valve seat sealing ring and butterfly plate sealing ring are both surfacing welded with cobalt-based hard alloy, creating a completely fused structure. The effective thickness of the alloy layer after processing is ≥ 2mm, ensuring exceptional strength and durability. The Rockwell hardness of the sealing surface after the surfacing process is HRC ≥ 50, ensuring the sealing surface will not fall off even with frequent opening and closing of the valve. This reinforces the longevity and stability of the valve, providing enhanced reliability and peace of mind to our customers. In summary, our Triple-eccentric all-metal two-way hard-seal butterfly valve offers superior sealing features and remarkable product advantages. Its unique structural design allows for online replacement of the valve seat and sealing ring, reducing downtime and increasing operational efficiency. The surfacing welded cobalt-based hard alloy guarantees outstanding sealing surface durability, providing a longer service life for both the sealing ring and the valve. Trust our valve to deliver exceptional performance and reliability in even the toughest working conditions. Structure Advantage: double eccentric full metal seal Bi-directional hard seal butterfly valve,unique structure design, make seat and sealing ring replacement on line to be realized. Sealing face advantage: machining the the seal ring of seat and disc after bead welding the cobalt based hard alloy on it,(effective thickness of alloy≥2mm) completely compound the hard alloy and base material together,the hardness of the sealing face HRC≥ 50 after the bead welding of cobalt based hard alloy,and will not peel out after long time and high frequency open/close. Sealing feature:enhanceing the anti-oxidization,wearing,eroding,corrosion features of the sealing face,safe operation under harsh condition,significantly reduce the friction factor of the sealing ring and face,prolong the life span of the sealing ring and valve.
