Manual spring return floating ball valve

Manual spring return floating ball valve introduction
Manual spring return floating ball valve is automatic reset, automatic return, two-piece structure, thread and flange connection.Manual spring return floating ball valve spring automatically returns to open and close only needs to rotate 90 degrees operation and the small rotation moment can connect the medium circulation.
Manual spring return floating ball valve is the main research and development of products, the characteristics of the ball valve is in the spring on the handle, in the spring of the handle into consideration to the long-term use can lead to the present situation of the spring is stretched or pull dead, in the interior design for spring adjustable tension and firmness, and the use after a period of time, which can spin down the lever, the internal nut tighten, (such as the need to slowly close to loosen the nut, let a lighter spring, to the effect of slow closing) the design of spring return ball valve is the traditional insurmountable.Spring automatic reset type ball valve in access, tank bottom, the use of mechanical equipment is very wide, compared with the traditional two-piece ball valve, not only can save trouble and effort, in some equipment can also prevent the loss of fluid caused by forgetting to close the valve.
Manual spring return floating ball valve is suitable for chemical industry, petroleum, electric power, pharmacy, beer, food, dairy beverage, cosmetics and engineering pipeline and other fields.

Manual spring return floating ball valve structure

Manual spring return floating ball valve charateristics
1. The fluid resistance is small, and the resistance coefficient is the same as the pipe section of the same length.
2. Simple structure, small volume and light weight.
3. Compact and reliable, the sealing surface material of the ball valve is widely used in plastic, good sealing, and has been widely used in the vacuum system.
4. Easy operation, fast opening and closing, rotation of 90° from full open to full close, convenient for remote control.
5. Easy maintenance, simple ball valve structure, sealing ring is generally active, disassembly and replacement are relatively convenient.
6. Simple structure, light weight, low flow resistance.
7. Simple operation, fast opening and closing, long service life.
8. When the ball valve structure is fully opened or closed, the seat seal is isolated from the medium and is not easily corroded by the medium or damaged by friction.
9. Spring reset structure, reasonable design, strong practicality.
 
Manual spring return floating ball valve working principle
The reset principle of Manual spring return floating ball valve is to add a spring at the handle. Taking the lever unilateral spring as the actual principle, the spring presses the handle when the handle is opened, and the spring pushes the handle to close when the handle is released. Its function is based on the principle of automatic spring rebound and reset.The Manual spring return floating ball valve is made of CF8 CF8M or other material and made of superior spring combination, with a service life of up to one million times or three years.Manual spring return floating ball valve is widely used in petroleum, chemical industry, light industry, food, medicine, environmental protection and other industries.
