Q:Role of ball valve DN20-Q11F-16: Q11F ball valve is to control the circulation and cut-off of the pipeline medium.

Q:What is the difference between floating and fixed ball valves?: Fixed ball valve is the ball with the lower stem fixed, pressure will not produce movement, therefore, in the design, two sealing ring must have sufficient preload to ensure that the valve seat and sphere seal, is a two sided forced seal. Thrust or sliding bearings are usually provided on the upper and lower stems of the ball.

Q:3/4 on the elbow of the water pipe. How about that ball valve?: 3/4 inches converted approximately equal to 20mm, that is, DN20, can be equipped with DN20 caliber ball valve, commonly used for brass material

Q:Valve and ball valve is the same thing? Don't know don't speak: Ball valves belong to a large class of valves, valves include gate valve, butterfly valve, check valve, globe valve, ball valve, trap valve, safety valve, etc. all valves

Q:Is the integral type split ball valve structurally identical?: Split type ball valve, the valve body by the main body and the cover body is composed of two parts, thread connection between the main body and the cover body is arranged at the connection of the sealing ring, an annular sealing ring and ball valve, valve rod, sealing gasket, valve stem nut, a handle, a fastening nut is arranged on the main body, there is another ring the sealing ring is arranged on the cover body, interface screw holes at both ends of the valve body are respectively processed in the main body and cover body. This structure of the ball valve, the ball cavity depth is relatively shallow, the ball cavity processing is more convenient.

Q:What are the advantages and disadvantages of the two functions of the pneumatic ball valve actuator?: Pneumatic ball valve actuator is divided into double action and single action two modes of work.Working principle of double action mode:When the compressed air enters the middle cavity between the two pistons of the cylinder from the air inlet (2), the two pistons are separated and moved toward the two ends of the cylinder, and the air at the two ends of the air chamber is discharged through the air port (4). At the same time, the two piston rack synchronously drives the output shaft (gear) to rotate in an anticlockwise direction. On the contrary, when the air source pressure passes through the air inlet (4) into the air chamber at the end of the cylinder, the two piston moves toward the middle of the cylinder, and the air in the middle air cavity is discharged through the air port (2). At the same time, the two piston rack synchronously drives the output shaft (gear) to rotate in clockwise direction. (if the piston is mounted in opposite directions and the output shaft rotates in reverse direction, that is, double acting reverse type).

Q:What is a high handle ball valve? What's the difference between it and ordinary ball valve?: Long distance between the valve casing and valve ball valve operating handle, mainly used for pipeline insulation, thermal insulation when the body is exposed in the insulation material,

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:How much pressure can the flange ball valve withstand?: How many can, each kind of pressure specification has the different material quality, the thickness request, the ball valve can also use in the high pressure class.

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.
