Description:                                                                                                                                                   


ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status.
Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to gates and globe valves, but they lack their fine control in throttling applications.
The ball valve's ease of operation, repair, and versatility lend it to extensive industrial use, supportingpressures up to 1000 bar and temperatures up to 752 °F (500 °C), depending on design and materials used. Sizes typically range from 0.2 to 48 inches (0.5 cm to 121 cm). Valve bodies are made of metal, plastic, or metal with a ceramic; floating balls are often chrome plated for durability. One disadvantage of a ball valve is that they trap water in the center cavity while in the closed position. In the event of a freeze, the sides can crack due to expansion of ice forming. Some means of insulation or heat tape in this situation will usually prevent damage.Another option for cold climates is the "freeze tolerant ball valve". This style of ball valve incorporates a freeze plug in the side so in the event of a freeze up, the freeze plug ruptures, (acts as a sacrificial disk), thus making for an easy repair. Now instead of replacing the whole valve, just screw in a new freeze plug. This is commonly called freeze plug technology.
In the case that a ball valve is used for cryogenics or product that may expand inside of the ball, there is a vent drilled into the upstream side of the valve. This is referred to as a vented ball. Safety is the number one concern when engineers specify a vented ball.
A ball valve should not be confused with a "ball-check valve", a type of check valve that uses a solid ball to prevent undesired backflow.
Other types of quarter-turn valves include the butterfly valve and plug valve and freeze proof ball valve

Instruction Manual :                                                                                                                                        
 
For pipe thread connection type ball valve,we should make sure the pipe being vertivcal against the end surface of the valve body when tighten the connection part.our special warning is that we should only wrench the octanal
At the same end of body instead of the other side to avoid deformation so as to affect its normal open function.
For internal thread type ball valve,we should control the length of the external thread at the pipe end in case deformation of the valve body caused by the external thread’s aqueezing the surface of the internal thread so as to affect leakproofness
When connecting the pipe thread type gate valve with pipe thread,the internal thread can be either tapered pipe thread or cylindrical pipe thread,but the external thread must be tapered pipe thread,otherwise it will cause leakage due to loose connection
When installing the pipe thread type ball valve,the sealing material must be clean.
Such obstacles as wall,coupling nut and pipe should not be placed inside the open/close range
When the ball valve handle is parallel to the body,it is open,otherwise,it is close

 

Application:                                                                                                                                                   


The ball valve is mainly used for cutting off,distributing and changing the direction of the flow medium in the pipeline,to prolong the service life of the ball valve,full open and full close are highly suggested
 

Competitive Advantage:                                                                                                                                 

 

1. Small resistance with the fluid

2. Small force is needed when open and close the valve

3. Unlimited by the direction of flow medium

4. Resistance between the working medium and the sealing surface is smaller than that of stop valve’s when the valve is opened completely
we can copperate with customer to build a warehouse with mutual benefit, save the purchase time

 

Quality control:
