For IVD (In vitro diagnostic) Devices manufacturers, a frustrating problem is that the solenoid valve controlling the waste emissions has often been blocked, resulting in the equipment failure.

Many manufacturers use rocker valve to control the waste emissions. Most of these valves in front of the instrument (the sampling part) are used to control the delivery of reagents or samples. If used in the latter part (the cleaning part), this valve is often blocked, because of faster waste flow, higher concentrations, and even blocky crystals. Thus, turning off the machine for maintenance and replacing parts is not only extremely costly, but also greatly affect the use of end users.

Oriwen provides reliable solenoid pinch valves for solving this problem. If used in the latter part (the cleaning part), Oriwen pinch valve will greatly reduce the block frequency and severity. Compared with the rotary valve, our pinch valve has smaller limit on the liquid, simpler liquid path and larger minimum interval, thus reducing the chance of blocking. The wear cycle of flexible tube in the pinch valve is predictable, so our customers can schedule periodic maintenance plan to ensure equipment normal running. Also, our users can easily replace the tube without professional help. Almost no moving part ensures the reliability of the operation. Only the easily replaceable tubing contacts with the fluid. Therefore, the user can also use ordinary detergent to clean outer surfaces of the tube. No complex valves group design; Oriwen Fluidics pinch valves can easily be integrated into existing systems and new devices.
