Q:What do you mean by 266 in the 266 brass ball valve?: This is the Ningbo aimeike Copper Valve Co Ltd model, 266 is only a brass ball valve series, specifically to check samples.

Q:What's the difference between a ball valve and a butterfly valve? Which one has better sealing performance?: Force code valve industry for you to resolve their differences:Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow, it only need to rotate 90 degrees of operation and a small rotating torque can be closed tight.Butterfly plate driven by the stem, if you turn 90 degrees, you can complete a headstock. Change the deflection angle of the butterfly plate to control the flow of the medium.Sealing performance of the ball valve is better than butterfly valve.

Q:The working principle of the track type ball valve: No wear and tear of switch:The ball core deviates from the valve seat and then rotates, eliminates the friction of the valve seat, and solves the abrasion problem of the seat of the traditional ball valve, gate valve and plug valve.Anti friction valve hard and dense cover:The surface of the ball core is welded with a hard polished sealing surface, which can ensure the sealing performance under very severe working conditions.

Q:Replacement method of PPR hot melt ball valve: The above problems belong to the wire type, and the name is: double live catch valve, directly loosen the lock nut, replace the valve can be.When the valve is purchased, the merchant sells a full valve. When the change is made, both ends of the live joint lock nut are removed and the valve is directly connected with the original lock nut on the pipe.

Q:What is the service valve?: In front of the valve will need to be all pass, that is, the hole and the ball valve line diameter consistent, the ball will not be card.

Q:How can a steel ball in a steel ball valve be put in?: This kind of ball valve usually has an external direction of compression, an arrow. Usually, the ball is filled from the direction of the arrow tail and inserted or tightened into the circlip.

Q:DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?: So you must first determine the pressure level of your ball valve, and then determine the valve flange used standards, and then you can determine the basic parameters of the ball valve flange.

Q:3/43/8 above the ball valve is not usually said of the big ball valve?: That is the calculation of the imperial, generally divided into two types, 1 inch (in.) 2, metric (mm) swap inch metric 1/4 (2) =6 3/8 (3) =10 1/2 (4) =12 5/8 (5) =16 3/4 (6) =18 7/8 (7) =22 1 1/8 (1 inch 1) =28,

Q:PPR ball valve diameter is 3 cm, what is the specifications?: The PPR32 ball valve with the DN25 is a specification. (DN25 is the nominal diameter of the pipe and PPR32 is the outer diameter of the pipe)The PPR25 ball valve with the DN20 is a specification.

Q:Ball valve use?: Ball valves are widely used in petroleum refining, long-distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, and play a decisive role in the national economy.
