GEMÜ 650TL manual tapping diaphragm valve

Description

The GEMÜ 650TL is a manual tapping diaphragm valve with automatic closing function which is designed for use in sterile applications. This piston actuated diaphragm valve has a “keep-closed” override of manual operation.

The GEMÜ 650TL manual tapping diaphragm valve can only be operated (opened / closed), if a control medium is applied to the actuator. When the control medium supply is switched off, the valve closes and can no longer be operated manually.

Example: If the flow velocity in a piping loop is reduced (e.g. if too many tapping points are open), flow may drop below a critical level.

This special  GEMÜ 650TL manual tapping diaphragm valve can be used to specifically close tapping points automatically via the central process control system in order to reduce the tapping quantity and thus to increase the piping loop flow velocity.
