Q: PPR ball valve which face is open, which face is closed, there is a o, there is a s, which is off, ah, which is open, well intentioned people told me that the original finished by forget: Hello, I am glad to answer for you. O is on, s is off. I hope I can help you.

Q: What are the uses and characteristics of copper ball valves?: 4, good sealing performance5, the direction of installation is not limited, the flow of media can be arbitrary

Q: What are the types of vacuum ball valves?: Vacuum ball valve refers to the work pressure is lower than the standard atmospheric pressure, forming a certain vacuum ball valveVacuum ball valve models are GUD, GDQ, KF16, GU, KF and so onVacuum ball valve type has electric, manual, pneumatic, such as GU manual vacuum ball valve

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 the sealing surface of the ball valve stand for HF?: HF is the abbreviation of two English words: "Hard Face", which means surface hardening. Usually surfacing is made of Tailai alloy (Alloy 6). Other surface hardening methods include hard chromium plating. This method is used more in the ball valve. But hard chromium plating is prone to small cracks, which reduces its corrosion resistance.

Q: Advantages of track ball valves: 1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section. 2., simple structure, small size, light weight. 3., close and reliable, at present the ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used. 4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control. 5., maintenance is convenient, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient. 6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface. 7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.

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: The valve nominal 1/2, 3/4 is how much?: Nominal diameter 1/2 3/4 corresponding to DN15 DN20

Q: Check valve, ball valve, check valve are used in what place, ah?: This problem may have two meanings: first, what are these pipe fittings used in? Two, globe valve, ball valve, check valve, their respective uses and occasions. First of all, these fittings are used in pipework, i.e., where gases, liquids, or gases are used as power sources. Therefore, almost all industries (Engineering) are required to use, especially chemical enterprises, water supply, hydraulic systems are more widely used.Pipe (valve) the most important parameters are the use of pressure, pipe nominal diameter, the use of medium, temperature, spool valve body material. Many types of valves, the most common are cut-off valve, gate valve, ball valve...... , check valve (many forms) is to prevent fluid back, such as the need to install the pump outlet, the pump stops to prevent fluid back, therefore, the fluid requirements in the process are not allowed back to places which need to install a check valve. Cut-off valve is mainly used for the need to cut off the fluid, it is good tightness (not easy to leak), but the resistance is greater. And the ball valve, its spool is a ball shaped body, simple structure, convenient switching, but its adjustment and pressure resistance is poor, so often used in the smaller diameter of the water pipe. For further information, please refer to the valve selection manual. If required, please provide the QQ mailbox for your electronic books.

Q: What are the advantages of an air operated ball valve in comparison with other types of valves?: In full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, will not cause the valve sealing surface erosion.Wide range of applications: diameter from small to a few millimeters, large to several meters, from high vacuum, high pressure can be applied. As the ball valve has a wipe in the opening and closing process, it can be used in suspension with solid particles in the medium.High processing accuracy: expensive, high temperature should not be used, such as impurities in the pipeline, easy to be blocked by impurities, leading to the valve can not open.
