Our solenoid valve consists of two sections; one is the valve part made of highly inert plastics like PTFE or PEEK, which opens and closes a flow path.
The other is the actuator made of a coil and metallic parts, driving the valve part. In order to preserve the purity of the fluid, a diaphragm is installed between the two sections in our isolation valves.
The diaphragm prevents the fluids from flowing into the actuator and protects the metallic parts from being corroded. Also, metal dust generated in the actuator does not contaminate the fluid. This structure is ideal for analytical and diagnostic applications which are sensitive to particles. It is also suitable for handling acids and chemicals which erode metals.
By reducing the size of these isolation valves, we have been able to
reduce the dead volume, improve the control of the pumping volume, and reduce the installation area, thereby improving accuracy and avoiding wasting chemicals and solvents.
