Probably the most hygienic way to shut off a media flow is if the valve does not touch the fluid at all - this is the principle on which the pinch control valve type 7077 operates. With this compact pinch control valve, the media flow in an endless tube is throttled or constricted by the pneumatic drive. The simple operating principle of the endless tube pinch control valve is ideal for many critical applications in the chemical, food and pharmaceutical industries.
