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 is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?
The difference between the three is as follows: pneumatic valve]: driven by compressed air valve. Operation principle: the pneumatic control valve is composed of actuating mechanism and regulating mechanism. The actuating mechanism is a thrust component of the regulating valve, which generates the corresponding thrust according to the pressure of the control signal, and drives the regulating mechanism to move. The valve body is the regulating component of the pneumatic control valve. It contacts the regulating medium directly and regulates the flow of the fluid. [hydraulic valve]: the use of oil and other liquid pressure driven valve. The working principle of the hydraulic valve control valve pressure control valve flow control valve control valve control valve to control the direction of hydraulic system oil flow direction or liquid flow through the valve two, the working principle of the valve core and the valve body and valve off valve two-way hydraulic lock check valve to make oil movement off or on, changing the direction of the oil flow, so as to realize the hydraulic actuator and its driving mechanism of starting and stopping or changing the direction of movement. [electric valve]: with electric actuators to control the valve, so as to achieve the valve opening and closing. The utility model can be divided into two parts, the upper part of which is an electric executor, and the lower half of which is a valve. Also called air conditioning valve. The electric valve is usually connected by the electric actuator and the valve, and it becomes an electric valve after installation and debugging. The electric valve uses the electric energy as the power to switch on the electric actuator to drive the valve and realize the valve switching and regulating action. So as to achieve the purpose of switching or regulating the pipeline medium.
Q:What does the torque of the valve mean?
Unit: Newton M. torque is the minimum torque used to turn on the valve. It is the force that opens the valve!The valve that indicates the opening of the PZ73X-10C DN50 requires 5 meters of force.
Q:What does "DN15" mean? What does "PN 16" mean?
Valve nominal diameter 15mm, valve nominal pressure 1.6MPa
Q:What does valve 41F-40C mean?
4: refers to the flange connection;1: on behalf of the structure of the form, different valves have different meanings;F: the sealing material is fluoroplastic;40: nominal pressure is PN40bar;C: the valve body is made of carbon steel, but the valves above PN25 shall be omitted from CAccording to the incomplete model provided, it is estimated that the ball valve is Q41F-40
Q:High and low pressure valve is how to distinguish?
Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.
Q:What is the KVS in the valve parameter?
KVS meaning in valve parameters:Kvs is the coefficient of flow (also called circulation capacity).Kvs refers to both ends of the valve pressure difference of 0.1MPa, water density of 1g/cm^3, when the valve fully open flow. It is an important parameter of the control valve, reflecting the capacity of the control valve.Flow coefficient is a unit of time, in the test conditions, the pipeline to maintain a constant pressure, pipe flow through the valve mass flow, or mass flow. That is, the maximum flow capacity of the valve. The greater the value of the flow system, the smaller the pressure loss when the fluid passes through the valve. The CV value of the valve shall be determined by test and calculation.
Q:What is a lift rod valve?
The valve stem and valve plate are relatively fixed, and the valve stem rises up when the valve plate is raised
Q:How to check if the gas valve is open?
There is a switch on the valve indicating that you can follow the above operation
Q:Where is the filling portion of the valve?
The valve stem and the body of the valve at the junction of the pressure cap, the pressure cap is filled inside.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications.
Q:Who knows what the DE stands for in the valve DE50?
No, DE is DG, and DG stands for nominal diameter of valve
