Flange Ball Valve

Q:PE pipe size diameter 3/8, diameter 1/4, material: low density polyethylene, pressure 170psi;Valve material: copper, and PE pipe connection interface with lock nut.Is this connection reliable? Will the pipe break due to excessive compression? Are there any requirements for the size of the joint and the size of the nut?: After the impact, for a period of time, PE pipe cracking phenomenon, this is what causes? This is connected to the tap water.Chasing the answerWhere is it cracked?!

Q:Hello, I would like to ask the household tap water valve selection of stainless steel ball valve or brass ball valve is better, thank you: I have used two kinds, but stainless steel gate valve is better. Note that it must be made of stainless steel 304. I bought more than 300 yuan a gate valve. Total valve, no way to save money.

Q:What are the differences between the pneumatic ball valve and the pneumatic angle seat valve?: Pneumatic angle seat valve is the use of reciprocating actuators, usually in use to withstand fluid work pressure at 1.6MPa. Pneumatic ball valve is to use rotary actuator, to bear high fluid pressure. In normal use, the reciprocating actuator is characterized by its service life over the length of the rotary actuator. Two: easy maintenance. Three: the price is cheap. Personal recommendations in fluid pressure below 1.6MPa, or pneumatic angle seat valve is better?. High pressure, less opening frequency, pneumatic ball valve is appropriate.

Q:The valve nominal 1/2, 3/4 is how much?: The 1 point is DN25 mm1/2 is DN15 mm3/4 is DN20 mm

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:What are the structural shapes of the eccentric hemisphere valve, what are their respective characteristics?: Two, characteristicsThe eccentric hemisphere valve is mounted type structure. The valve installed on the pipeline can be directly checked and maintained, which can effectively reduce the device parking and reduce the cost.Eccentric semi spherical valve is single valve seat design. The utility model eliminates the problem that the medium of the valve in the valve is influenced by the abnormal voltage increase.Low torque design. Special structural design of the valve stem, with only a small hand, the valve can easily open and close.No friction at opening and closing. This function completely solves the problem that the traditional [wiki] valve [/wiki] affects the sealing because of the friction between the sealing surfaces.Wedge sealing structure. Valve is provided by the mechanical force of the valve stem, the ball wedge to the seat and seal, so that the valve sealing is not affected by changes in pipe pressure, in a variety of conditions, sealing performance has a reliable guarantee.The self-cleaning structure eccentric semi ball valve sealing surface. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.

Q:Please professional help guide: accidental discovery of connection pipe and valve (mark position diagram) can rotate, but there is no problem with the 10 Water Leakage.Please professional help guide: accidental discovery of connection pipe and valve (mark position diagram) can rotate, but there is no Water Leakage problem, while the valve under the same position is fixed and can not rotate, will this situation is normal? Is it possible to leak water in the future?: This nut should be tight and can not move. There is a rubber pad in it, so it is not leaking at all. It will leak for a long time. It is suggested that the wrench should be tightened clockwise (from top to bottom)

Q:The two valves are available for the flow of the electromagnetic valve switch, I contact more, found for water solenoid valve are caged water, to repair several times because of impurities or newly installed pipeline with raw materials flowing through the valve, close the valve body when not to rely on Yan, a seepage water tank to diffuse phenomenon!I am looking for a replacement, I think the electric valve should be a good choice, not used to a conclusion.Please use the electric ball valve to talk about friends, or for the two kinds of friends who have an understanding to talk aboutOr there is no better substituteThere seems to control the solenoid valve and electric valve is not the same, the solenoid valve is normally open and closed to control the electric valve is controlled by the trigger (like), if used to replace it, what is the controller?: I think you should use the solenoid valve is diaphragm type, and not particularly good products, diaphragm solenoid valve in the closed position when the diaphragm is easy to change, resulting in pipe die, or medium impurities caused the pilot hole is blocked, the valve will not move, so the diaphragm solenoid valve. Is there a film guide card member, so that each position of the diaphragm in the correct position, but the pilot hole is not a solution, of course, you can use direct action solenoid valve, such problems are solved. The electric ball valve than the pilot solenoid valve in this respect, but the cost of this fear is much higher, especially the pipe diameter is not so, it does not pay!

Q:Butterfly valve and ball how to distinguish from the appearance: To say the difference, the biggest difference is that the butterfly valve is a piece of open and close, and the ball is a ball. They work by spinning their own axes!(1) the butterfly valve from the valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the seal the performance of the valve than the butterfly valve well;(2) butterfly valve structure is relatively simple, low pressure general use butterfly valve, butterfly valve the maximum pressure can only reach 64 kilograms. Ball valve structure is relatively complex, more resistant to high pressure, the ball valve up to 100 kg.(3) butterfly valves are divided into soft seal and seal, soft seal butterfly valve is generally perpendicular to the center of the plate, is the valve plate, valve seat, valve stem is the center position of the highest temperature soft sealing butterfly valve is 150 degrees below the pressure of 16 kg, hard seal butterfly valve can be divided into single eccentric, double eccentric three, the eccentric, we generally use more than three eccentric, because the three eccentric according to its structure, better sealing performance, hard seal butterfly valve pressure is 64 kg;(4) the valve can also be divided into soft seal and seal, soft seal valve can reach the highest temperature below 280 degrees, the pressure is below 64 kilograms, hard seal ball valve temperature can reach 425 degrees below the pressure below 100 kilograms.

Q:Why is there a water or oil in the new ball valve?: The test has leaked;Pressure test, lubrication ah!
