1.Structure of  Ball Valve Description

Threaded ball valve is closed is a ball, ball around the center line of the body as a rotation to achieve a kind of open and close the valve.
Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Two type ball valve, three type ball valve, is widely used in recent years a new type of valve, the valve average installation. And ball valve is a kind of ball valves, threaded pipe connection is screwed connection, and flanged ball valves, welded ball valve, etc.

2. Main Features of the Ball Valve

• Small flow resistance;

•  Simple structure

• Small volume, light weigh

• Small volume, light weigh

•  Easy to operate, open and close quickly, facilitate remote contro

• Easy maintenance, sealing ring, which generally remove easy to change

• Full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through does not cause the valve sealing surface erosion.

5.FAQ

1. What's are the characteristics of ball valve?

The distinct feature of a ball valve is the sealing surfaces between the gate and seats are planar, so ball valves are often used when a straight-line flow of fluid and minimum restriction is desired. The ball valve faces can form a wedge shape or they can be parallel. 

2. What is the work principle of ball valve

 The ball valve faces can form a wedge shape or they can be parallel. Ball valves are primarily used to permit or prevent the flow of liquids, but typical ball valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, ball valves are often used in the petroleum industry. 

3.  What is the structure?

Bonnets provide leakproof closure for the valve body. Ball valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.

Q:What are the main types of gate valves?
According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve.
Q:What do you mean by forged steel gate valves 800LB DN20 SW?
Forged steel gate 800LB pressure DN20 is by SW said socketweld (connection)
Q:What is wire feed gate valve? What do you say in French?
Point to the wire gate valve. Refers to the valve body with internal thread or external thread, and pipe thread connection. Also called thread valves, threaded valves, valves within the toothFlange gate valve is connected to the flange gate valve, this connection is the most common wayThe main difference is the connection
Q:Soft sealed gate valve and hard sealing gate valve which good?
If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.
Q:Gate valve is gate valve, gate valve specifications, model code is generally what?
Gate valve is not gate valve, gate valve does not have a fixed specific model
Q:Analysis of the advantages of elastic seat sealing gate valve?
When the elastic seat sealing gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the flashboard is pressed to the valve seat of the other side only by the medium pressure to ensure the sealing of the sealing surface, which is self sealing.
Q:What does gate z41t-10 150 mean?
According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150
Q:What is a protective gate valve? What is gate valve knowledge?
it is up to the function of a single valve can not reach the exit of the product is installed in the water supply pipe and the head of civil air defense to conveying medium to stop, wave and wave combination, to prevent internal shock wave into the system engineering facilities, so as to eliminate the destructive shock wave, to protect the system facilities normal operation and safety protection purpose.
Q:How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.
See, you choose 100 of the pressure is not high, you can not flange
Q:TitleThe difference between gate valve, butterfly valve and stop valve
The gate (gate valve) is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle gate valve. The direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle.Gate valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex
