Digipinch valve

Pinch Modificata 02 768X876 (1)

The Digipinch valve is a pinch-type, normally closed valve with on/off and proportional closed-loop control.

These valves are the perfect solution for dosing or dispensing liquids with high precision and no drift over time in the cleanest and most sterile way as they are never in contact with the liquid. In fact, the Digipinch through its shape memory actuator proportionally controls the force, and therefore the pressure, applied to the tube containing the liquid, regulating its flow.

The Digipinch valve has a very low power consumption, up to 20 times lower than traditional solenoid valves, and silent operation. It can also be directly interfaced to external pressure, flow or temperature sensors so that it can be closed-loop controlled to the target fluid dynamic function. 

Each valve can be easily customised to meet the most stringent functional requirements of different applications, in terms of electronic and mechanical interface, fluidic performance and control electronics and communication on IoT platforms
