Solenoid Valve Media Viscosity

The majority of 2/2 and 3/2 solenoid valves will work with fluids up to a maximum viscosity of 40 or 50 Centistokes viscosity (CST). The only exceptions to this rules are the special 2/2 and 3/2 Co-axial solenoid valves, special application solenoid valves and angle seat piston valves that can work up to 600 Centistokes and beyond.

Viscosity is the measurement of a fluid's internal resistance to flow. This is typically designated in units of Centipoise or poise but can be expressed in other acceptable measurements as well.

Some conversion factors are as follows:

Helpful Hint: Ask your chemical supplier for your media's viscosity, and compatable materials as they are supposed to know.
