BioPAT®PinchValve

The BioPAT^® Pinch Valve is a tube pinch valve comprising one valve body and one control drive. The BioPAT^® Pinch Valve is only intended for automatic pinching of tubes. The valve body of the BioPAT^® Pinch Valve may only be used in combination with the Sartorius control drive for BioPAT^® Pinch Valves. The BioPAT^® Pinch Valve can be used for both opening and closing applications, as well as for applications which require the flow rate to be reduced through linear positioning of the pinch mechanism between the open and closed position. Once the tubing is correctly installed in the BioPAT^® Pinch Valve and the lid is close, the degree of “openness” of the tubing can be controlled by moving the gripper and spindle connected to the motor in the drive towards or away from the lid. To open the tube again, the drive pulls the shaft and the gripper deeper into the body, while the gripper is slightly closing to bring the tube back to its original form. For more information about different closing conditions and possibil-ities, see the Operation Instruction of the system. The re-opening mechanism is a purposely designed feature in the BioPAT^® Pinch Valve gripper to promote the re-shaping of the tube cross-section after long periods being closed. To open the tubing, the levers on the gripper push the walls of the tubing inwards, while the spindle and gripper move away from the lid.
