Basics of stainless steel ball valve
Just use stainless steel ball valves is rotated 90 degrees operation and a small torque can be closed tightly. The body cavity of full equality for the media provided little resistance, through the flow channel. The main features of valve is its own compact, easy operation and maintenance, stainless steel ball valve can be used to control the flow of air, water, steam, corrosive media, mud, oil, liquid metals and radioactive fluids and other types of media. Ball valve can be integral, it can also be modular. This type valve in the pipe should generally be installed horizontally. Stainless steel instrumentation ball valves Category: stainless steel pneumatic valve, stainless steel electric ball valves, stainless steel ball valves manually. Stainless steel ball valve material is divided into 304,316,321.

the use of high pressure ball valves
In Western countries, industrialized countries, the use of high pressure ball valves is on the increase year by year, in China, the ball is widely used in petroleum refining, long-distance pipelines, chemical, paper, pharmaceuticals, water conservancy, power, municipal, steel and other industries , occupies a pivotal position in the national economy.
The main features of the high-pressure valve is its own compact, reliable sealing, simple structure, easy maintenance, with the spherical sealing surface often in the closed state, not easily be eroded media, ease of operation and maintenance for water, solvents, acids, and natural gas and other general working medium, but also to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, in various sectors has been widely used. stainless steel ball valves can be integral, it can also be modular.

Stainless steel ball works and valve structure diagram
stainless steel ball valve works
Ball works by rotating the spool to the valve flow or occlusion. Valve switch light, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, with the spherical sealing surface often in the closed state, the media can not easily be eroded, in various sectors has been widely used.
Stainless steel ball valve structure diagram
Ball and proportional relief valves belong to the same type of valve, only its closure member is a sphere, the sphere rotating around the center line of the valve body to achieve the open, and close a valve.
Valve in the pipeline is mainly used for cutting, distribution and change the direction of media flow. Ball valve is a new valve is widely used.

High pressure ball valve has rapidly developed into one of the main valves
FD-LOK High pressure ball valve came in the 1950s, with the rapid development of science and technology, continuous improvement of production processes and product structure, in just 40 years, it has rapidly developed into one of the main valves.
High-pressure Ball valves is mainly used for cut off or connected line of medium, it can also be used to adjust and control the fluid, which has a strong V-shaped seal between the hard ball with its V-ball core surfacing carbide metal seat shear force, especially for fiber-containing tiny solid granule and other media. The multi-way valve in the pipe can not only control the confluence flexible medium, diversion, and flow switch, but also to close any channel leaving the other two channels are connected. This type valve in the pipe should generally be installed horizontally.

Stainless steel ball valve advantages
FD-LOK stainless steel ball valve advantages:
1, fluid resistance is small, the pipe resistance coefficient equal to the same length.
2, simple structure, small size and light weight.
3. Close and reliable stainless steel ball valves sealing surface material widely used plastic, sealing, and has also been widely used in the vacuum system.
4, easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation 90 °, to facilitate remote control.
5, easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient.
6, in the fully open or fully closed, the sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion of the valve sealing surface.
7, a wide range of applications, from small to a few millimeters in diameter, large meters, from high vacuum to high pressure can be applied.
FD-LOK Ball valves has been widely used in various sectors of petroleum, chemical, power generation, paper, atomic energy, aviation, rockets, as well as people's daily lives.

Pneumatic high vacuum valve has the following advantages:
1, fluid resistance, FD-LOK Trunnion ball valves is the smallest of all valves in a fluid resistance, even reduced diameter valve, the fluid resistance is quite small.
2, valve switch quickly and easily, as long as the stem is rotated 90 °, Ball completed fully on or off action, it is easy to open and close fast.
3, good valve sealing performance. three way ball valves seat seals are generally manufactured using an elastic material such as polytetrafluoroethylene, easy to guarantee the seal, and valve sealing force with increasing media pressure increases.
4, valve stem seals and reliable. When the valve opening and closing the valve stem rotates only, so the stem packing seal can not easily be damaged, and the stem back seal sealing force increases media pressure increases.
5, ball valves open and close only 90 ° rotation, it is easy to achieve automatic control and remote control, stainless steel ball valve can be configured pneumatic devices, electrical equipment, hydraulic equipment, gas-liquid interaction devices or electro-hydraulic linkage.
