Product Description
Serial floating valves are mainly applied to natural gas, chemical engineering,metallurgy, city building,environmental protection, pharmacy and food industries, among which the anti-sulphur series used for long delivery pipes of natural gas that contains hydrogen sulphide medium, a lot of impurity and corrosive substances. Notes:Our company can provide products at customers' requirement. The sizes of serial valve connecting flange and butt-welding terminal can be designed according to customer's requirement.

Product Feature
The design features of the floating ball valves include:1. Specific Sealing Structures of Valves include:Double cant elastic sealing or V-shaped groove seal ring sturcture design is adopted to ensure sealing reliability. As for low-pressure,ultra-low pressure or vacuum-operated ball valves,a plate spring-loaded sealing structure of valves base is adopted to ensure their long-term sealing reliability. As for moderate or high temperature ball valves, Para-Position polyphenylene or mental can be adopted for valve bass material.2. Automatic Pressure Relief StructureWhen the pressure in cloaca cavity increases singularity, the cavity medium can push valve base by its own thrusting force, which result in automatic pressure relief and valves security assurance.3. Reliable Sealing of Valve RodThe valve rod adopts downward installation structure with back sealing. The sealing force will increase toghther with the heightening of medium pressure,which can ensure the sealing reliability. Moreover, even if the pressure in valve cavity increases singularly, the valve rod will not burst out.4. Fire-resistant StructureAccording to the operating condition and users requirement, ball valve can be designed with a fire resistant sturcture up to the fire-resistant standards of API607 and JB/T6899 Once the soft seat ring is burnt out on fire, the structure can avoid series leaking of the medium and prevent fire from scaling up.5. Anti-static SturctureWhile operating the valves, the friction between the sphere and the base will produce static charges accumulating on the sphere. To avoid static sparkle, the fire-resistant device is designed to derive the accumulated static sparkle, charges from the sphere.6. Locking DevicesA locking sturcture is designed on the full-open and full-close spots of manual ball valves to avoid abnormal open-and-close produced by misoperation or unpredictable circuit vibration. On production lines of petroleum and chemicals of flammable mediums,and during the course of outdoor piping, the design is especially advantageous and practical.7. Full Bore Structure and Reduced Bore Structure:The two structure series are produced to meet different requirement of users. The passage inside diameter of full ball valves is the same as that of valve pipe, which is convenient for pipe cleaning. The weight of retractive diameter ball valves is relativ-ely lighter, but the fluid resistance is just 1/7 that of stop valves with the same caliber. Therefore, the application prospects of retractive diameter series is much better.
