Product Description

Metal Seated Floating Ball Valve

Metal Seated Floating Ball Valve developed by CHAODA Valves Group has the structure of spring pre-loaded seat to avoid the stuck phenomenon. This structure could ensure the tightly touch between the sealing surface of ball&seat ring when valve is in the closed position. Moreover, it could eliminate the stuck phonomenon  which is caused by the expansion of internal parts because of the impact of high temperature as the spring pre-loaded seat could absorb the expansion.

To ensure the perfect sealing of the Q41H Metal to metal sealed ball valve, we use many advanced hardening technology according to different working condition and needs such as ultro-sonic spray coating, nickel base spray welding, surface specially hardening, STL spray welding, ceramic material with high strength&hardness property. The surface hardness of the ball and seat coulld generally reach more than HRC60, and maximun up to HRC74 and the material of sealing face could stand temperature of 540ºC, and maximun 980ºC.

Metal Seated Floating Ball Valve product description

Metal Seated Floating Ball Valves (Flanged general or butt-welding connection optional) are suitable for using on various kinds of pipeline from pressure Class 150 to Class 1500, PN16 to PN100 to cut off or allow the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/worm gear/pneumatic or electric actuators could be chosen by needs.

Ball valves are an important mechanical product related with society construction, national defense construction and people's life. Ball valves are used on the pipeline to cut off or connect the flowing of meduim in the process/industries of : The process of mining/refining/transporting Petroleum, natural gas, coal; The manufacturing process of chemicals/pharmacy/food; The system of hydropower, firepower, nuclear power; The rural/urban system of water draining, heating and gas supply; The irrigation and draining system of farmland and also the manufacturing system of metallurgy.
