Working principle of sanitary ball valve

A precisely manufactured ball with a through cavity is placed between two flanges and two PTFE valve seats in the valve body. A valve spindle acts on the ball by 90° rotation, thus opening or closing the valve.

At the same time, a valve seat cleaning joint can be added to clean the ball valve cavity and discharge it through the drain hole.

The sanitary ball valve is operated by a pneumatic head or manually by a handle.

The series of sanitary ball valves have three structures:

The sanitary ball valve is a three-piece structure, consisting of two flanges, a valve body and two PTFE valve seats. It is installed with bolts. A valve seat cleaning joint can be added to clean the ball valve cavity and discharge it through the drain hole.

The sanitary ball valve is a three-way ball valve with two structural forms: T-type and L-type. It consists of a valve body, a valve cover and a PTFE valve seat, and is installed by thread.

The sanitary ball valve is a two-piece structure, consisting of a valve body, a joint and two PTFE valve seats, and is installed by clamping. A valve seat cleaning joint can be added to clean the ball valve cavity and discharge it through the drain hole.
