Q:That is to say, there is still a difference The man in the workshop said it was one thing... It's completely confusedHere are the data for the two valves. Please consult with the experts.Ball plug valve, high temperature cast steel, A216Gr.WCB flange, two pass, full quantity type 3, X 150LB RF ball / rod, 13%Cr seat, PTFE handle openBall valve Q41F-150LB-3"

Ball, ball, hole, rotary ball, control, closureBall valve and plug valve is almost straight round solid ball.

Q:The difference between ball valve q41f46-16c and q41f46-16

There is no difference. If the latter model is P, then the stainless steel flange lining fluorine ball valve, the former is cast steel material.Q41F46-16C is the type of ball valve, cast steel flange lining fluorine ball valve!

Q:What's the difference between T ball valve and L ball valve?

This is the code for the three way ball valve and the three way plug valve flow passage. The L shape can only connect the two channels perpendicular to each other, and the T shape allows the three channels to communicate with each other or to connect two of them.

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.

Q:What is the principle of forced sealing ball valve? How to achieve mandatory sealing function? Is it suitable for high pressure conditions?

With spring to achieve forced sealing, not applicable to high pressure

Q:What does "DN PN" mean? DN25 PN18 stands for what is the thickness? With the usual said 4 in charge of what's the relationship?

*DN25 nominal diameter 25MM*PN18 nominal pressure 18 kg / cm2

Q:Under what circumstances with the butterfly valve, under what circumstances with the ball valve?

Selection principle of ball valve:1, oil, natural gas transmission mains, need to clean the pipeline, and be buried in the ground, all pass by, the ball valve full welded structure; buried in the ground, select all pass through ball valve welded connection or flange connection; pipe flange connection, welding, selection of connection, all pass through or shrink the diameter of the ball valve.2, product oil pipeline and storage equipment, choose flange connected ball valve.3, the city gas and natural gas pipeline, choose flange connection and internal thread of the floating ball valve.1 、 in the oxygen piping system of the metallurgical system, the fixed ball ball valve should be selected after the strict degreasing treatment and the flange connection.2, low temperature medium piping system and device, should choose to use the valve cover of low temperature ball valve.3 、 the lifting rod type ball valve can be used on the pipeline system of the catalytic cracking unit of the oil refining unit.4, chemical systems such as acid and alkali corrosive media and piping systems, it is appropriate to choose austenitic stainless steel, PTFE seat sealing ring for all stainless steel ball valve.5 、 metal to metal sealing ball valve can be used in metallurgy system, power system, petrochemical equipment, piping system or device of high temperature medium in city heating system. 6, the need for flow regulation, you can choose the worm gear drive, pneumatic or electric with V shaped opening of the regulating valve.

Q:Q41F-16-64P this is the ball valve, what type, please answer in detail, thank you!

Q--- ball valve4---- flange connection1----- ball valve is floating ball (ball valve has floating ball and fixed ball points, 7 represents the fixed ball)F----PTFE- PTFE seal (PTFE PTFE),16-64---- ball valve nominal pressure is 16-64 kg (1.6-6.4Mpa)P---- ball valve body material is 304 stainless steel

Q:What is the ball valve Q11F -16 material?

If sealed, F stands for fluoroplastic. Valve material is not marked in the model!Q stands for ball valvesThe first 1: threaded connection,Second 1: is the ball valve is floating through the ball,F stands for PTFE- PTFE seals16 represents the nominal pressure of the ball valve is 1.6MPa=16 kg

Q:What is the difference between ball valve and plug valve?

The main advantages of plug valves are as follows:Suitable for frequent operation, quick and easy opening and closing.Fluid resistance is small.The utility model has the advantages of simple structure, relatively small volume, light weight and convenient maintenance.Good sealing performanceFree from the direction of installation, the flow direction of the medium can be arbitrary.No vibration, little noise.Plug valve installation and maintenance should pay attention to the following matters:Leave the valve handle in a rotating positionCannot be used as throttling.
