Mini Ball Valves
A mini ball valve is a short-bodied brass ball valve with a small handle designed for small-bore lines. Fitted before instruments and gauges in tight spaces, it allows the line to be shut off during maintenance or replacement.
The smallest sizes of the brass threaded ball valve family, including 1/8″, are in this group. With female-female and female-male versions they are used on pressure gauge, pressure switch, sampling and pneumatic device connections.
Main Applications
- Before pressure gauges and pressure switches
- Sampling points
- Pneumatic devices and filter connections
- Small-bore water and air lines
- Laboratory and test rigs
