A Floating Ball Valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body, it drifts toward to the downstream side and tightly pushes against the seat under the medium pressure to ensure sealing reliability. The floating ball valve has simple structure, good sealing performance but the seat material is required to withstand the workload since the sealing pressure is bared by the seat ring. Due to unavailability of high performance seat material, floating ball valve is mainly used in middle or low pressure application.
The Floating Bal...
Top Entry Ball Valve brief introduction
Its most difference from common ball valve is that its maintenance can be made on pipe line and without dismounting from the pipe line.The back space seat structure is adopted for the seat and the rear portion of seat retainer is oblique angle to prevent accumulation of impurity from affecting back space of seat.
Top Entry Ball Valve Predominance
1.Top entry ball Valves are designed with double slopping surfaces. Functioned by the springs, they automatically adjust the tightness among the valve seats, valve body and...
Pneumatic Ball Valve widely applicable to industries' fluid control or adjusting control, complete a set use with automation pneumatic meter. These industries including natural gas, oil, chemicals, metallurgy, paper making, electrical power, mining industry, printing, biological pharmacy, daily chemicals, food and beverage, water treatment and air treatment .
Pneumatic Ball Valve in the pipe is mainly used to cut off so fast, media distribution and changes in the flow direction. Pneumatic Ball Valve is widely used in recent years a new type of valve, it has the fo...
Cryogenic Ball Valve is mainly applied to various fire control systems station road, turn on or shut off the pipeline medium. Suitable medium: water, steam and other non-corrosive media.compared to the other valve products ,the charactery of Cryogenic Ball Valve is high temperature and high pressure,the unique self-sealing design, the higher the pressure, the more reliable seal.
Cryogenic Ball Valve Features:
1.Positive ball cavity relief to prevent dangerous overpressure due to thermal expansion.
2.Pressure safe stem assembled inside the body for blowout preve...
Swing Check Valve operates in the same manner as ball and cone valves, but the plug that settles over the opening is a disk. Disk and cone valves tend to wear down more because they have more moving parts and because they get bumped around on top of the flow of water when it is turned on.
Swing Check Valve are suitable for nominal pressure PN1.0MPa ~ 42.0MPa, Class150-2500; nominal diameter DN15 ~ 1200mm, NPS1 / 2 ~ 48; working temperature -196 ~ 540 ℃ for various pipeline, used to prevent the media back. Through the use of different materials, applicable ...
The Pressure Seal Check Valve design incorporates a metal-to-metal seal that becomes tighter as the pressure increases. The initial preload deforms the taper on the soft iron gasket to mate with the taper on the bonnet. The thin knife-edge on the gasket is wedged tightly between the body and the bonnet. The shallow angle insures that the gasket is sealed tightly with only a small upward force on the bonnet. Once the initial seal is created, the body/bonnet joint will remain leak free regardless of thermal or pressure conditions in the valve.After the joint has been assemb...
The disc in a Tilting Disc Check Valve is unguided as it fully opens or closes. There are many disk and seat designs available, in order to meet the requirements of different applications. The valve allows full, unobstructed flow and automatically closes as pressure decreases. These valves are fully closed when flow reaches zero, in order to prevent backflow. Turbulence and pressure drop in the valve are very low. The flapper valve in a flush-toilet mechanism is an example of this type of valve. Tank pressure holding it closed is overcome by manual lift of the flapper. I...
A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug can be screwed in to close (or shut) the valve.
Forged Steel Pressure Seal Globe Valve is used in Oil Refining and other industrial applications where forged steel material is required. Higher pressures and temp...
The Bellows Seal Valve cartridge is welded to both the valve bonnet and the valve stem. The Bellows Seal Valve cartridge has a number of convolutions and these convolutions become compressed or expanded depending upon the movement of valve stem. (Scientifically speaking the Bellows Seal Valve gets compressed when the valve is in the open position and expanded when the valve is in the closed condition). It is important to properly install the valve bodies. The Bellows Seal Valve can be sealed to the valves in two different ways. Firstly, the Bellows Seal Valve can b...
A Wafer Butterfly Valve is equivalent to a ball valve except that the ball-shaped mechanism inside of is replaced by a disc or plate that rotates on a rod or trunnion. Not like the ball valve, which presents a perpendicular encounter to the flow, the butterfly valve can be positioned both perpendicular to parallel to the flow. This development makes it feasible for for movement management (termed throttling) that the ball valve isn't ready to attain. Given that the disc is usually existing within the flow, a butterfly valve triggers a strain drop, irregardless of its st...
Some people would like to find suppliers from the internet. Because the internet contact such as email and msn (the most common IM tool in business) is no cost and fast.
Here I give you an idea a very common way to search sellers on the internet.
For example: you are looking for a Knife Gate Valve and Pressure Seal Gate Valve
The most common search engine: www.google.com www.yahoo.com www.msn.com
Maybe you consider that go to the search engine and type “Knife Gate Valve”,how ever you would to easy to get the suppliers, you would always find some Knife Ga...
No:GB/T 12220-1989English Name:General purpose industrial valves-MarkingValve type normally should show the type of drive, connection type, structural features, the sealing surface material, body material and the nominal pressure and other factors. Standardization of valve type of valve design, selection, selling more convenient. Valve types and materials of today, more and more of the valve model is also more complex preparation. Although our preparation of a unified standard valve model, but increasingly unable to meet the needs of industrial development in the valve. At present, the ...
