Ball Valve

GAIRUI 3PC Forged Steel Floating Ball Valves 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.

Female threaded ball valves are suitable for using on pipelines of medium or low pressure to turn off or swith on pipeline medium. Operation manners are in general of manual, and pneumatic or electric actuators are available.Based on design structures, the valves get divided into three pieces, two pieces, and one piece types. Female Threaded ball valve & butt welded ball valve could be divided into one piece, two piece and three piece body. Advanced casting technology is used for body with reasonable structure and beautiful appearance. Elastic seat material is adopted to ensure reliable sealing together with easy operation.

The ball valve with clamp connection has the characteristics of natural anti-static structure, anti-misoperation structure and reliable sealing of valve stem. The valve body adopts an integral structure. Through precise processing and assembly, the ball core is loaded from one end, and the compression ring is tightened to keep good contact and sealing between the two soft sealing seats and the ball core. The valve pressure ring inner gasket is also well sealed so that the leakage of the valve is zero. Because of the integral structure of the valve body, so the valve to achieve ultra-short flange distance, the weight of the machine greatly reduced, only about 50% of the same kind of ordinary ball valve.

Principle of the forged steel floating ball valve: This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet.

Cast Iron Ball Valves are used in commercial, industrial, and process applications requiring a non-corrosive body finish or where a clean cosmetic appearance is desired.

Ball valves are mainly used to cut or connect medium in the pipeline, and can also be used to regulate and control the fluid. The hard sealed V ball valve has a strong shear force between the V core and the metal valve seat of the hardfacing hard alloy. It is especially suitable for the medium containing fiber and small solid material. The multi - ball valve can not only flexibly control the switching of the flow, shunt and flow of the medium, but also close any channel and connect the other two channels. This type of ball valves should be installed horizontally in pipes.

The trunnion ball valve is used to cut off or connect the media in various of Class150~Class2500. The valves made of different materials are suitable for various media such as water, steam, oil, liquefied gas, natural gas, coal gas, nitric acid, oxidizer, urea and etc. The driving modes include manual operation and electric operation. The connection ends can be flange or butt welding.

The DBB double ball valve is designed to replace the complicated connection of multiple valves in the traditional pipeline. Reduce the leakage point in the system, quickly achieve emissions and shut down function. The DBB double ball valve saves the installation space limit. The installation program is simplified. Reduce the pressure of the pipe system. It is convenient to clean and maintain the instrument and reduce the cost. DBB double ball valve has two series of full diameter and reduced diameter. The inside diameter of the full diameter ball valve is in line with the inner diameter of the pipeline, not only with small fluid resistance, but also convenient for pipeline cleaning. The fluid resistance of the shrink ball valve is much lower than that of the same caliber cut-off valve. The weight of the ball valve is about 30% lighter than that of the same caliber ball valve, which effectively reduces the cost and price of production, thus it has been widely used.

The cryogenic ball valve is applicable to different pipeline.By adopting different materials, the cryogenic ball valve is applicable to different working temperature and medium.The minimum temperature for the ball valve is -196 Degree C . The operation of the ball valve can be manual operated, gear operated, pneumatic operated and motor operated. The end connection usually is flanged ends. However, the welded ends are also optional.

The cryogenic ball valve has two types: floating ball and trunnion mounted ball. For their range, face to face dimension and flange dimension, please refer to the corresponding data of common floating ball valve and trunnion mounted ball valve. For valves with working temperature above -50 Degree C, long neck design is seldom adopted. For valves with working temperature below-50 Degree C, the neck length T shall be 250mm, or shall be decided as per our own design and calculation.

The three - way ball valve can be divided into L type and T type. The L type three way ball valve is used to switch the medium flow direction, so that the two vertical channels can be connected. The three way ball valve usually adopts the two seat structure, and it can also adopt four seat structure according to the user's request. The four valve seat sealing three ball valve has beautiful shape and compact structure. It can not only switch the flow direction of the medium, but also make the three channels interconnected. At the same time, it can close any channel, make the other two channels connected, and flexibly control the flow or shunt of the medium in the pipeline.

The pneumatic ball valve is a pneumatic actuator with a ball valve. Pneumatic actuators perform relatively fast, and the fastest switching speed is 0.05 seconds / times, so it is usually called pneumatic quick shut-off of ball valves. The pneumatic ball valve is usually equipped with various accessories such as the solenoid valve, the gas source treatment triad, the limit switch, the locator, the control box, etc. to achieve local control and long distance centralized control. In the control room, the valve switch can be controlled. It does not need to run to the scene or at the high altitude and the dangerous zone. It saves human resources, time and safety.

GAIRUI series electric actuator is used for controlling valves of 0-270 Degree rotation and other similar products, such as butterfly valve, ball valve, damper, flapper valves, cock valves, etc.. It is widely used in petroleum, chemical, water treatment, shipping, paper making, power plants, heating, light industry and other industries. It can be drived  by 380V/220V/110V AC power or 24V/110V DC power. Control signal can be 4-20mA current signal or 0-10V voltage signal. It can move the valve to desired position, realize automatic control. The maximum output torque is up to 2000N·m.
