Describe
product name Q341F worm gear ball valve
Product number Q341F
Nominal diameter DN15-300
Pressure range 1.6-4.0MPa
Body material Cast iron, cast steel, stainless steel
 
The ball valve independently developed and produced by our factory is reliable in quality, reasonable in price and perfect in after-sales service.
 
Worm gear ball valve is suitable for all kinds of light and heavy industry and building pipelines. Quality, global sharing! Ball valves are widely used in: chemical, petrochemical, petroleum, paper, mining, electric power, liquefied petroleum gas, food, pharmaceutical, water supply and drainage, municipal, machinery Equipment supporting, electronics industry, urban construction and other fields.
 
Ball valve features:
 
(1) The fluid resistance is small, and the full-diameter ball valve has substantially no flow resistance. (2) Simple structure, small size and light weight. (3) Close and reliable. It has two sealing faces, and the sealing surface material of the ball valve is widely used in various plastics, and has good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems. (4) It is easy to operate, and it can be opened and closed quickly. It can be rotated by 90° from full opening to full closing, which is convenient for long-distance control. (5) Convenient maintenance, the ball valve has a simple structure, and the sealing ring is generally active, and it is convenient to disassemble and replace. (6) When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and when the medium passes, it will not cause erosion of the sealing surface of the valve. (7) Wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied. (8) Since the ball valve has wiping property during opening and closing, it can be used in a medium with suspended solid particles.
 
Q341F worm gear ball valve overview:
 
Worm ball valve is an important type of valve, widely used in petrochemical, long-distance pipelines and other fields. The closing member of the ball valve is a spherical ball (or a partial ball) with a hole that rotates with the valve stem to open or close the valve. Among the various valves, the flow resistance of the ball valve is the smallest. When the full-diameter ball valve is opened, the ball passage, the valve body passage and the connecting pipe are equal in diameter and formed into a diameter, and the medium can flow almost without loss. When the ball valve is rotated by 90°, it can be fully closed and opened and closed quickly. Compared with gate valves and globe valves of the same specifications, the ball valve is small in size and light in weight, which is convenient for pipeline installation.
