Takasago's solenoid diaphragm valve consists of two parts.One is the valve part, which opens and closes the flow path, and the other part is the actuator part, which operates the valve part.A membrane (diaphragm) inside the valve isolates these two parts from each other.The diaphragm prevents fluids running inside the valve part (made of highly inert plastics such as PTFE and PEEK) from flowing into the actuator mainly made of metals.This function of the diaphragm prevent fluids from corroding the actuator.Over the cycles of operations, metal dusts etc. are generated from the actuator, and the diaphragm also prevents the dusts from mixing into fluids.


This structure is ideal for applications such as sampling devices of analytical instruments and medical instruments, which do not tolerate impurities.It is also suitable for handling acids and chemicals which corrode metals.A valve with this kind of structure is also called "(chemically) inert valve."
