Spring return ball valve

Spring return ball valve introduction

Spring return ball valve is automatic reset, automatic return, two-piece structure, thread and flange connection.Spring return handle 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. Spring return ball valve is suitable for chemical industry, petroleum, electric power, pharmacy, beer, food, dairy beverage, cosmetics and engineering pipeline and other fields.

Spring return 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 return handle 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 ball valve features

1. Spring Return Closes the valve when not held open.

2. Spring Return Handles are manufactured from heavy duty stainless steel components to withstand frequent use in refueling, sampling, drains and other applications that require positive closure of a manual valve.

3. The Spring is enclosed within the tubular handle of the valve thus preventing possible finger trap hazards.

4. Spring Return Ball Valve utilizes live loaded packing, which provides longer periods between packing adjustment and maintenance, reducing the need for valve maintenance.

5. Providing safe operation for both general and industrial chemical applications.

6. Ball Valve with Spring Return Handle has a locking device as standard to lock the valve in the preferred position.

7. Spring returen ball valve with a direct mounting pad that allows the Fail Close

8. Spring Handle or “Dead Man Handle” to be fitted.

9. Spring return ball valve is usually used when the application requires a reliable positive fail close operation when user disengages the lever.

10. Operating torque approximately three times standard valve torque.

11. Spring Return Ball Valve available from 1/4” to 4” Thread, Socket Weld, Sanitary Tri-clamp or Flanged Ball Valve and other End Connections.

12. Torque range available up to 100 N.M., valve ensures tight shut off and is versatile for wide range of flowing media.

How does a spring return ball valve work?

The reset principle of spring return 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.Spring return handle 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.Spring return handle ball valve is widely used in petroleum, chemical industry, light industry, food, medicine, environmental protection and other industries.
