The GEMÜ 650TL diaphragm valve is a manual tapping valve with automatic closing function which is pneumatically operated. The "keep-closed" override of manual operation is via a stainless steel handwheel. The 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. — Hermetic separation between medium and operator — Ergonomic handwheel — Additional pneumatic actuator for closing from a central control system — CIP/SIP capable — Optional flow direction and installation position
