FAQ
1. Can3 4 brass ball valves be used in drinking water pipes?
Yes, but the premise is that the brass ball valves used meet the sanitary standards for drinking water pipes, such as lead-free brass materials or products certified by NSF and WRAS, to avoid the impact of impurities or lead precipitation in brass on water quality.
2. How to determine the switch state of 3/4 brass ball valves?
Usually, the handle of the ball valve is in the open state when it points to the direction of the pipe, and in the closed state when it is perpendicular to the direction of the pipe. Some ball valves will have indicator marks, which makes it easier to determine the switch position.
3. Why are 3 4 brass ball valves suitable for frequent operation scenarios?
The brass ball valve has a compact structure, only 90 degrees of rotation is required for opening and closing, and the handle is simple and light to operate, which is suitable for use in environments with frequent switching. In addition, it has good sealing performance and can remain stable after multiple switches.
4. When using a 3 4 ball valve, is it necessary to lubricate it regularly?
Generally, it is not necessary, but if it is used in a high temperature or high pressure environment for a long time, it is recommended to lubricate the sealing parts appropriately every year to extend the service life of the valve.
5. If the 3 4 inch ball valve is leaking, what could be the cause?
Common causes include aging of the seal, damage to the ball, loose tightening during installation, or excessive wear of the valve. It is recommended to check the seal or replace the ball valve with a new one.
