Spring return self closing ball valve introduction
Spring return self closing ball valve is automatic reset, automatic return, two-piece structure, thread and flange connection.Spring return self closing 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.The characteristics of the Spring return self closing 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 self closing ball valve is the traditional insurmountable.Spring return self closing 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.
Spring return handle ball valve is suitable for chemical industry, petroleum, electric power, pharmacy, beer, food, dairy beverage, cosmetics and engineering pipeline and other fields.
