Chaoda Valves Group is specialized in manufacturing Ball Valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc.
CHAODA GROUP WENZHOU E-BUSINESS CO.,LTD. is a wholly owned subsidiary of CHAODA VALVES GROUP CO.,LTD.With Chaoda valves group( CHAODA group") quality management and safety system(Get the approvals of ISO9001,ISO14001,OHSAS18001, API6D, CE/PED, API607,API6FA, ISO15848-1, TS and API600 gate valve certified),top level developing team(Provincial Key Enterprise research Institute,Provincial Key Enterprise Technology Innovative Group, Provincial Enterprise Technology Center),advanced machining equipment, well chemical analyst and inspection equipment(Optical Spectrometer, Helium low emission tester, High & Low temperature performance equipment and etc)we could provide our clients with perfect products and satisfied service.
Ball valves (Flanged general and butt-welding connection optional) are suitable for using on various kinds of pipeline from pressure Class 150 to Class 1500, PN16 to PN160 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 valve is used to cut off, distribute or change the flowing direction of medium. 90°'s turning with very small torque could seal the valve very well.
Floating ball valve has a good sealing performance, however, we need to consider whether the outlet side seat could bear the working pressure as the movable ball would nearly pass all the medium pressure to the seat. For this reason, the floating structure is generally for middle & low pressure working pressure.
CHAODA Ball Valve has the features of Good sealing, reliable, safety and long life span. Ball Valve developed by Chaoda has following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc.
CHAODA VALVES GROUP CO.,LTD. launched its quality management and safety system as ISO9001,ISO14001,OHSAS18001, API6D, CE/PED, API607,API6FA, ISO15848-1 TS and API 600.
Reliable Seat Seal
The structure design of elastic sealing ring has been adopted for ball valves. This seat design features a bigger sealing pressure ratio between the ring surface and the ball when medium pressure gets lower, where the contacting area is smaller. Thus, the reliable seal is ensured. When the medium pressure gets higher, the contacting area between seat ring and ball becomes bigger as the sealing ring transforms elastically to undertake the bigger force pushed by the medium without any damage.
Fire Safe Design
With the valve heated in a fire application, the non-metal material parts such as seat sealing ring of PTFE, stem back seat gasket, gland packing, and the sealing gasket between body and bonnet might disintegrate or be damaged due to high temperature. CHAODA's specially designed structure of auxiliary metal to metal seal is provided to effectively prevent both internal and external leakage of the valve. As required by customers, CHAODA's ball valves with fire safe design can meet the requirement of API 607, API 6FA, BS 6755 and JB/T 6899 .
Reliable Stem Seal
The blow-out proof design has been adopted for the stem of ball valve to ensure that even if the pressure in the body cavity is risen accidently and the packing flange becomes invalid, the stem may not be blown out by medium. The stem is equipped with a backseat design, being assembled from underneath. The sealing force against the backseat gets higher as the medium pressure becomes higher. thus to ensure the reliable sealing of stem under variable medium pressure.
