 DuraChoice Full Port Brass Ball Valves are an economical alternative to stainless steel versions. Rated at 600 PSI (water, oil, and gas), these full port valves are strong enough for many applications. Their full port design allows unrestricted flow to reduce cavitation and pressure drop. Not for potable water. For potable water we recommend this valve, VBB02.

The valve threaded to the pipe end is connected to the pipe thread, where the internal thread may be cylindrical or conical and the external thread must be conical.
The gate valve connected with internal thread is connected with the pipe end, and the length and size of the external thread at the pipe end should be controlled.In order to avoid excessive pipe end into the top pressure gate valve thread inside the face, resulting in seat deformation and affect the sealing.
For the valve connected with pipe thread, the hexagon or octagonal position on the same end of the thread should be wrenched when the installation is tightened, and the hexagon or octagonal position on the other end of the valve should not be wrenched to avoid deformation of the valve.
