The pneumatic pinch valve type 7079 is a low dead space control valve and at the same time insensitive to dirty, abrasive and pasty media. Decisive for universal use is the straight hose passage for the operating medium — no flow deflection. The hygienic design using FDA-compliant tube materials as well as the simple design principle offer users from the chemical, food and pharmaceutical industries a real alternative.
