P200-O Low-power miniature rotary valve

5-10 VDC - max. 0.5 A - weight 300g

Miniatur Motorventil (Low power) P200-O


OEM motor valve with compact design and low power consumption of only 0,5 A (peak). With a weight of only approx. 300g this rotary valve is especially suitable for microfluidics and mobile applications.

A position sensor (encoder) with additional signal transmitters on the valve head enables precise positioning of the individual channels and automatic position detection when the valve is started - also known as "homing".

The valve body is made of PCTFE, which offers high chemical resistance and good strength. The plunger is made of PTFE, which has the same chemical properties as the valve body. Precise channels with only 0.5mm allow smallest internal volume and transfer volume from port to port. More about the different valve head configurations can be found in the valve heads section
