What is standard bore brass ball valve

standard bore brass ball valve is a device made of brass to control the switch and flow rate of pipeline fluid. Usually the valve body and bonnet of standard bore brass ball valve are made of forged brass, the core of the switch mechanism is the brass ball with a hole inside of the standard bore brass ball valve, which uses the back and forth action of the ball core to rotate 0-90° around the axis of the valve stem, so as to achieve the purpose of opening or closing the valve.

Standard bore brass ball valve specifications are DN8 to DN100 (corresponding to 1/8 to 4 inches), working pressure range is PN8 to PN40 (corresponding to 50 to 600WOG), and operating temperature range is between -20-180 degrees Celsius.

Standard bore brass ball valve and stop valve are the same type of valve, the difference only lays in its closing part is a ball or cone. Standard bore brass ball valve in which the ball rotates around the centerline of the valve body to open and close. It is usually used in medium and low pressure fluid pipelines to switch off or adjust the medium.

Standard bore brass ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It cannot be used as a regulating valve. It can only be fully opened or fully closed when in use. Otherwise, the sealing seat will be easily damaged and corroded.

Structure and components of standard bore brass ball valve

▶  Valve body: 
The material is brass, and the surface treatment includes nickel plating, chrome plating, natural color and pickling. Chrome plating is more expensive than nickel plating. Different countries and markets require different raw materials.

▶  Valve ball: 
The material is brass, and the surface is chrome-plated. Generally, in order to save cost and facilitate the use of large-sized products, solid balls are used for valves below φ39, hollow balls are used for valves above φ39, and solid balls are generally flat-bottomed balls to reduce weight. The surface roughness and roundness of the ball are one of the most important factors that directly affect the tightness of the brass ball valve.

▶  PTFE Seat
Also known as TEFLON, the chemical name is polytetrafluoroethylene, which has excellent chemical stability, no chemical effect with strong acid and alkali chemicals, high heat resistance and cold resistance, the temperature used is generally -20 degrees Celsius ~ 130 degrees Celsius, and the friction coefficient is very high. It is a good self-lubricating material and mainly used as a chemical corrosion-resistant, high-temperature-resistant seal, for packing, gasket, brass valve seat, etc..
     
▶  O-ring (rubber gasket)
NBR---the code name of our material is 66B, which is divided into 66B-1 and 66B-2.66B-1 is soft, 66B-2 is hard.
At present, the hardness of the O-ring is generally 65; the greater the hardness, the better the wear resistance; but more than HA80, the greater the brittleness

▶  Valve stem: 
The valve stem is divided into an O-ring structure stem and a pressure cap structure stem. The O-ring structure valve stem is sealed with O-rings, while the pressure cap structure valve stem is sealed with packing. The valve stem of the pressure cap structure is divided into top-loading and bottom-loading.

▶  Handle:  
The handle is used to open and close brass ball valve. From the color point of view, the handle is divided into red, yellow, blue, green, white and black. Usually different colors indicate different media: red generally indicates higher temperature medium; yellow indicates gas medium (European countries), so the valve with yellow handle is an gas ball valve; blue generally indicates lower temperature medium; white generally indicates cold air medium ; Black generally means oily medium

  Valve Bonnet: 
According to the shape, it can be divided into hexagonal cap and octagonal cap.

How standard bore brass ball valve Works

The standard bore brass ball valve opens and closes quickly and easily. Easy to operate, quick to open and close, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control and easy maintenance.

The standard bore brass ball valve controls the rotation of the valve ball through the rotation of the handle, so as to realize the control of the fluid medium. The basic working method is as follows:

1.Turn the handle to start the switch

2. Brass ball valve body for support and protection

3. Sealing seat: between the valve body and the valve ball to keep them sealed and prevent the medium from flowing out or leaking

4. Medium flow direction: the medium can flow in and out from either end of the brass ball valve body

5. Valve ball: The valve ball is connected to the handle through the valve stem. When the water flow hole of the valve ball and the medium flow in the same direction, the valve body is opened, otherwise the valve body is closed.

Application of standard bore brass ball valve

Btandard bore brass ball valve has good sealing performance. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and when the medium passes through, the valve sealing surface will not be eroded.

Wide range of applications, suitable for a variety of fluid pipeline media: water, oil, gas, steam, etc. Application areas: household water supply system, household gas pipeline system, mechanical equipment, chemical equipment, general parts, industrial equipment, water supply and drainage equipment, papermaking equipment, pharmaceutical equipment, general equipment, petrochemical equipment, power equipment, metallurgical powder equipment, mining equipment , municipal, electronic industry, etc.

Chemical compositions for standard bore brass ball valve

Standard bore brass ball valves are made of copper alloys with zinc as the main additive element, and have a beautiful yellow color. They are often used in the manufacture of valves, water pipes, connecting pipes for internal and external air conditioners, and radiators. Brass with different mechanical properties can be obtained by changing the zinc content in brass. The higher the zinc content in brass, the higher the strength and the lower the plasticity. The zinc content of brass used in the industry does not exceed 45%. No matter how high the zinc content is, it will cause brittleness and deteriorate the alloy properties. In order to improve certain properties of brass, the brass that adds other alloying elements on the basis of one-dimensional brass is called special brass. Commonly used alloying elements are silicon, aluminum, tin, lead, manganese, iron and nickel. Adding aluminum to brass can improve the yield strength and corrosion resistance of brass, and slightly reduce the plasticity. Brass containing less than 4% aluminum has good comprehensive properties such as processing and casting. Adding 1% tin to brass can significantly improve the resistance of brass to seawater and marine atmospheric corrosion, so it is called "navy brass". Tin also improves the machinability of brass. The main purpose of adding lead to brass is to improve machinability and wear resistance, and lead has little effect on the strength of brass. Manganese brass has good mechanical properties, thermal stability and corrosion resistance; adding aluminum to manganese brass can also improve its performance and obtain castings with a smooth surface. Brass can be divided into two categories: cast and press-worked products.

Depending on the copper and zinc content of the brass material, we assign brass numbers to form industry norms.
The commonly used brass grades and components are as follows:
