Q: What's the difference between angle valve and ball valve?: Angle valve is called "angle valve", because its inlet and outlet are 90 degrees angle perpendicular to each other, rather than straight into the ball valve straight out. Angle valve to cut off media, to facilitate the maintenance of terminal equipment, generally used for washbasin, kitchen sink, toilet water tank, water heater, cold and hot water inlet pipe. When an accident occurs in the water pipe or breaks and leaks after many years, then the angle valve is closed, which does not affect the normal water consumption at home and avoids economic losses.The ball valve has the same rotation 90 degrees of movement, different is the cock body is the sphere, has the circular through hole or the passage through its axis. 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. Ball valve is the most suitable switch, shut-off valve, but the recent development of the ball valve has been designed so that it has throttling and control flow, such as V ball valve.

Q: How does ball valve indicate?: Valve type designation method is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear Edition

Q: What is the maximum temperature resistance of the 304 stainless steel ball valve?: What seal do you have?.PTFE sealing maximum temperature: 120 degreesMetal seal maximum temperature: 325-400 degrees, look at the manufacturers.

Q: The difference between a cricket valve and a constant pressure valve: Ball valve for ball ball column shape and called, is mainly to be closed, and often switch when the fluid flow control to throttle function and design, is the main characteristic of effective throttling, to minimize and reduce the phenomenon of drawing valve and valve seat dip (wash) inhibition, but because of the seat is parallel to the line, change the flow of fluid through the valve seat will be in class.

Q: The difference between ball valve Q341F and Q347F: 7: fixed ball valve, F: fluorine plastic valve seat sealStructural distinction:Floating ball: ball valve is floating, in the media under pressure, that the ball can produce a certain displacement, and tight at the outlet end of the sealing ring, to ensure that the export side seal, a single side forced seal.Fixed ball: the ball of the ball valve is fixed, the pressure does not produce movement, therefore, in the design, two sealing ring should be sufficient pre tightening force to ensure sealing, double sided forced seal.

Q: What is the diameter of the 2 inch ball valve?: The internal diameter of the valve is generally international to inch, the domestic standard for DN, 2 inches of ball valve, its inner diameter is DN50.

Q: What type of ball valve is Q17F-10T?: Q17F-10T is copper and copper alloy internal thread, L type three way ball valve, is fixed ball

Q: Three electric ball valve type T and type L what is the difference?: Three way ball valve generally adopts two seat structure, can also be used according to user requirements four valve seat structure. Four seat sealed three pass ball valve, with beautiful appearance, compact structure and reasonable

Q: What's the meaning of the ball valve bore 14 "x 12"?: The inner diameter of the two ends of the ball valve is 14 inches at one end and 12 inches at the other.
