Does the ball valve half-open and half-closed cause damage to the valve?

With proper operation and maintenance, semi-open, half-closed operation of a ball valve usually does not cause damage. However, frequent position changes can lead to wear, and excessive force can also damage valve seal faces. Depending on the material selection and temperature range, avoid media and temperatures that exceed the capacity of the ball valve. Follow the manufacturer's instructions for proper operation and maintenance of the ball valve. Ball valves can be protected to the greatest extent
The design of the ball valve generally allows for half-on, half-off operation between fully open and fully closed. Under normal use and proper maintenance, half-open, half-closed operation usually does not cause damage to the ball valve.

Valve Position: Ball valves should remain in a fully open or fully closed position for a longer period of time. Frequent switching between half-on and half-off may cause valve wear, especially under high pressures, high temperatures, or corrosive media.


In summary, with proper operation and maintenance, the half-on, half-off operation usually does not cause damage to the ball valve. Following the manufacturer's guidance and operating according to the actual situation can maximize the protection of the ball valve and extend its service life.
