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 540℃ and
Material: Carbon Steel,Stainless Steel,Alloy Steel,Duplex Stainless
Operation: Manual,Gear Operated,Electric Operated,Pneumatic
Applicable: Oil,Chemical,Natural Gas,Petrochemical,Coal Chemical
and so on

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 ofThe 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.
Metal Seated Floating Ball Valve product features
The metal seated Ball Valve developed by Chaoda has following good
characteristics: good sealing performance, reliable safety
guarantee, long life span and etc.
1. The lever could be made in carbon steel or stainless steel with
stopping plate which could also equipped with locking device in
case of wrong operation. There is clear mark of "open&close" on
2. The stem with blow-out proof features used for metal seated ball
valve is integrated forged with hardness HB220~250.
3. Braided or flexible graphite packing is used to ensure reliable
sealing of stem.
4. Anti-static features.
5. Nnormally floating type for DN150, trunnion type for DN200.
6. Emergent grease injection: emergent injection device could be
installed in seat and stem to realize urgent sealing. And could
have extened stem for installing convenient if needed.
