The GEMÜ 660 2/2-way diaphragm valve has a stainless steel piston actuator and is pneumatically operated. The valve was designed for dosing and filling a wide range of products. All metallic actuator components are made of stainless steel. Normally closed (NC), Normally open (NO) and Double acting (DA) control functions are available. A stroke limiter and seal adjuster and an optical position indicator are integrated as standard. —Optional flow direction and installation position —Stroke limiter and seal adjuster easy to adjust —Precise stroke scale on the cover, 10 scale points per turn (one full turn corresponds to 1 mm stroke) —Improved sealing —Distance sleeves for the diaphragm available (not for steam applications) —2 control air connectors in flow direction, 4 control air connectors as an option, two of which are arranged across the flow direction —Fast cycle duties due to minimized filling volume —Electrical position indicators on request

The GEMÜ SUMONDO® single-use diaphragm valve consists of a diaphragm valve body and a manual or pneumatic operator. The single-use diaphragm valve body has an internally welded diaphragm. The single-use diaphragm valve body is fastened to the operator using a clamp. The valve body and the operator are locked using a defined closing and opening procedure. After use, the single-use diaphragm valve body and its diaphragm can be removed from the operator and disposed of. The operator can be used multiple times and remains in the plant. — Tried and tested actuator design — Impact resistant, corrosion resistant — The diaphragm valve body meets the purity requirements of the pharmaceutical industry (USP 85, USP 788) — Integral optical position indicator — Validation Guide on request — Gamma-sterilizable valve body

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
