Forged Brass Female Thread Mini Ball Valve With Nickle Plated
***Brief introduction of ball valves
Ball valves, the GB/T21465-2008 Valve Term describes it as followed: kinds of valves whose starting and stopping parts are drove by valve rod and do orbiting roll with the axes of valve rod.The ball valves is used to cut off or connect the medium in pipeline, it also can be used to control and adjust of flow. The V type ball core of sealed V type ball valves has strong shear force with the metal valve seat of surfacing cemented carbide; it is especially suit for the medium containing fiber and small solid particles. The multi-way ball valves not only can adjust the confluence, split-flow of medium and control the changing-over of flow direction; it also can close one of the pipelines and connect the other two pipelines.
Ball valves came out in the 1950s. With the rapid development of technology and the continuously improved of productive technology and product structure, ball valves has developed to a main valves in 40 years. In western countries, the use of ball valves is rising year by year. In our country, ball valves is extensively used in many areas, such as the petroleum refining, long-distance pipeline, chemical industry, paper making, pharmacy, water conservancy, electric power, municipal administration, steel and so on. All in all, ball valves occupy a very important position in national economy.

***The installation of ball valves
At first time, will be confused. During the installation, you should follow the steps and notice something.
The steps of install ball valves
1.Take off the protective covers on sides of flange end. Then wash the ball valve at the state of full-opening.
2.Before installation, you should process the complete machine test according to the specified signal (electric or gas), the purpose is to avoid the influence of use performance caused by shock. If the test is qualified, then you can install the ball valves.
3.Before connect the ball valves with pipeline, you should clean the impurities in the pipeline, or the impurities will damage the ball valves.
4.During the installation, do not use the executive body of valves as the hoisting point of jack-up, to avoid damage the executive body and components.
5.The ball valves should install at the horizontal or vertical direction of pipeline.
6.The pipeline near the install point shouldn't have the phenomenon of droop or external force. You can use piping support or upholder to eliminate the deviate.
7.After connecting with pipeline, do locking the connecting bolt of flange.
The things you should notice during the installation of ball valves
1.Do leave the place for spinning the valve handle.
2.Do not use ball valves as throttle.
3.The ball valves with transmission mechanism should up-right installed.
