The DV509-UV-LF, a high-duty diaphragm valve for dispensing ultraviolet (UV) resins, employs a wetted chamber that is compatible with low- to medium-viscosity UV materials. The valve is rated for 200 cycles per minute, and it sports a lightweight, compact design that is particularly suitable for automated systems. A diaphragm seal is attached to a solenoid that opens upon receiving an air signal from one of the company's valve controllers. The diaphragm then flexes to allow fluid to exit for the duration the seal is open. Finally, a return spring snaps the diaphragm shut after the air signal is removed. I&J FISNAR INC. Fair Lawn, NJ.
