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: What q25r-j159 BB-F-TE-NB represents American Standard ball?: Each letter has different meanings. Such as model, connection mode, material, driving mode, etc.%021 $3461#$%9331^^ hope Shanghai Yiling valve to help you answer

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: Are ball valves and float valves a thing? If not, what valves belong to the valve, screw valve, threaded flange valve, welding flange valve or flange valve?.Online, etc.. Thank you: They're not the same.1. ball valve: refers to the valve spool (seal components) for the ball shaped valve, collectively known as ball valves.2. floating ball valve is a ball without supporting shaft, the sphere was two seat clamping, which is "floating" state, it is mainly used in the pipeline to cut off, distribution and change the direction of media flow. Floating ball valve mainly has seat seal design, reliable reverse sealing valve, sealing rod, fireproof electrostatic function, automatic pressure relief and locking device and other structural features.

Q: How can the eccentric hemisphere valve be repaired? What are the things you should pay attention to when installing?: 6, the valve driving device to a fastening bolt before debugging, not allowed to loose. When the valve is used for a long period of time if there is leakage, the driving device limiting fastening bolts loose, counterclockwise rotation of a circle and a locking nut, the valve closed, due to eccentric action to eliminate wear clearance, to ensure that the valve to use, must not be forced to close the valve without release driving device a fastening bolt limit case, this will damage the drive device.7, eccentric semi ball valve is a one-way valve seal, valve seal for the arrow on the body, rather than the medium flow, installation when used as a cut-off valve, and the same medium flow arrow (i.e. being installed), when used as a check valve is used, instead the arrow with the direction of medium (reverse installation).

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?: First, 170psi pressure is not great, not excessive extrusion and rupture of polyethylene, but there will be stress relaxation phenomenon, is a long time there will be some loose, suggest you nut and pipe with tight mechanical connection is good, the data has not been studied, can only give you a suggestion: 24-48 hours after the installation is complete then a proper tight.

Q: Ball valve? I require the valve to control both sides of the liquid, one side with liquid flow, and the other side closed!: Three way reversing ball valve. Three way ball valves are T and L. The T type can cause three orthogonal pipes to connect with each other and cut off third channels, thus diverting and merging the channels. Two pipeline L three ball type valve can only be connected mutually orthogonal, communicating with each other while maintaining the third pipeline, only as a distribution function.

Q: For example, how many sizes and pressures are used in the two piece?: First of all, the difference between a ball valve and two chip, three chip ball valve is a ball valve flow, the internal structure of the necking design belongs to the design, the same diameter ball valve products must be smaller than the other two kinds of ball valves flow more. Compression capacity is not as good as two, but better than the three chip. A ball valve has the advantages of low cost, low price; the two valve is the three products in the most excellent in resistance and flow, the valve inside is preferred; features three ball valve design structure is easy to install, because the three ball valve can be installed by dismantling during installation, so in different pipeline even some other connections are completely no problem, fast loading, thread, flange, welding and so on, so the market is the most complete connection number of ball valve, especially when welding, a chip ball valve and the two valve can not be opened due to installation, want to welding in the pipeline it would be easy to the inside of the PTFE (similar to plastic) in a burnt out, the best choice at this time is three piece ball valve. But the disadvantage of three piece ball valve is the poor compression ability.

Q: Our factory has part of the ball valve in the direction of movement and normal ball valve is the opposite direction: anti clockwise for the turn off, clockwise. Excuse me, what's the reason for this?Excuse me, is this because the valve body installs the reason of the contrary or the reason, the ball valve is thus designed?Are there any positive and negative points when the ball valve is installed?: Ordinary ball valve is the reverse turn off, the general ball valve without direction requirements. Each kind has the direction request, generally has the arrow or the nameplate explanation on the valve body.
