NPV Series Diaphragm Isolation Proportional Valves

Orifice diameter 4.0mm

NPV Series Disphragm Separated Proportional Valves


2/2-way proportional diaphragm isolation solenoid valve with fluid separation.

With these valves the flow rate can be controlled via the operating voltage.

Wetted materials exclusively made of PTFE enable use in applications that require a high chemical resistance.

The adjustable flow rates are:

0 - 30 l / min (ΔP= 100 mbar, air)

0 -   4 l / min (ΔP= 1,000 mbar, water)
