Model Name:Ds363Y-25C DN1600 Introducing our revolutionary new product, the Five-eccentric all-metal two-way hard-sealed ball valve. This innovative valve combines structural advantages with unique features to provide unmatched performance and reliability in various industrial applications. One of the key structural advantages of our ball valve is its cylindrical body welding structure design. This design allows for online replacement of the valve seat and sealing ring, making maintenance and repair quick and easy. Gone are the days of having to dismantle the entire valve for seat or ring replacement, saving valuable time and resources. The sealing surface of our ball valve is another area where it stands out from the competition. Both the valve seat sealing ring and the valve core sealing ring are surfacing welded with cobalt-based hard alloy and then processed. This process ensures a seamless fusion between the base material of the sealing ring and the hard alloy. The resulting Rockwell hardness of the sealing surface after surfacing cobalt-based cemented carbide is HRC ≥ 50, guaranteeing a durable and long-lasting seal even under demanding conditions. The improved sealing features of our ball valve are truly exceptional. With enhanced oxidation resistance, wear resistance, erosion resistance, and corrosion resistance, our valve is built to operate safely even in harsh working environments with granular media. Additionally, the reduction in the gap between the sealing ring and the sealing surface significantly lowers the friction coefficient, reducing the wear and tear on the sealing surface and prolonging the service life of both the sealing ring and the valve itself. In conclusion, our Five-eccentric all-metal two-way hard-sealed ball valve is a game-changer in the industry. Its structural advantages combined with its exceptional sealing features make it the ideal choice for any application where reliability, durability, and performance are crucial. Trust in our valve to deliver superior results and redefine your expectations of what a ball valve can do. Structure Advantage: Pentad eccentric full metal Bi-directional hard sealing ball valve,unique column structure design, make seat and sealing ring replacement on line to be realized Sealing face advantage: machining 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.
