GEMÜ 660

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 actuator parts are made from stainless steel (except seals). Normally Closed (NC), Normally Open (NO) and Double Acting (DA) control functions are available. An opening stroke and closing stroke limiter and an optical position indicator are integrated as standard.

• Easily adjustable, integrated opening stroke and closing stroke limiter
• Precise stroke scale (10 scale points per turn) on the actuator top
• High level of reproducibility of the flow rates thanks to distance sleeves integrated in the shut-off diaphragms
• Fast cycle duties due to minimized filling volume
