Floating Ball Valve

Cast Steel Floating Ball Valve | Forged Steel Floating Ball Valve

Floating Ball Valve

Serial floating ball valves are mainly applied to natural gas, oil products, chemical engineering, metallurgy, city building, environment protection, pharmacy, and food industries, among which the anti-sulfur series are used for long delivery pipes of natural gas that contains hydrogen sulfide medium, a lot of impurity and corrosive substances.

The design features of the floating ball valves include

Speciffic Sealing Structure of Valve Base

Double cant elastic seal ring or V-shaped groove seal ring structural design is adopted to ensure sealing reliability. As for low- pressure, ultralow pressure or vacuum-operated ball valves, a plate spring-loaded sealing structure of valve base is adopted to ensure their longterm sealing reliability. As for moderate or high-temperature ball valves, Para-position polyphenylene or mental can be adopted for valve base material.

Full Bore Structure and Reduced Bore Structure

The two structure series are produced to meet different requirements of users. The passage inside the diameter of full diameter ball valves is the same as that of the valve pipe, which is convenient for pipe cleaning. The weight of retractive diameter ball valves is relatively light the fluid resistance is just 1/7 that of stop valves with the same caliber. Therefore, the application prospects of retractive diameter series are much better.

Automatic pressure relief structure

When the pressure in the cloaca cavity increases singularly, the cavity medium can push the valve base by its own thrusting force, which results in automatic pressure relief and valve security assurance.

Anti-static Structure

While operating the valve, 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.

Fire-resistant Structure

According to the operating condition and user requirement, a ball valve can be designed with a fire-resistant structure up to the fire-resistant standards of API607. API 6FA and JB/T6899.0nce the soft seal ring is burnt out on fire, the structure can avoid serious leaking of the medium and prevent the fire from scaling up.

Reliable Sealing of Valve Rod

The valve rod adopts a downward installation structure with back sealing. The sealing force will increase together with the heightening of medium pressure, which can ensure the sealing reliability. Moreover, even if the pressure in the valve cavity increases singularly, the valve rod will not burst out.

Locking Device

A locking structure is designed on the full-open and full-close spots of manual ball valves to avoid abnormal open-and-close produced by the 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.
