Quantitative dispensing of solvents, strong acids and strong alkali materials, and UV (ultraviolet) curing resins.
The pneumatic Teflon diaphragm valve EV22-120/130 series uses a Teflon diaphragm for sealing in the wetted parts, preventing liquid from leaking into the drive section. Its compact and lightweight design (22 mm) makes it easy to integrate into automatic machines and use in parallel or multi-channel configurations. The flow adjustment screw allows for the adjustment of the valve's opening and closing stroke, enabling precise small volume dispensing. The EV22-120 features wetted parts made entirely of Teflon (fluororesin), providing excellent chemical resistance. The EV22-130 has a wetted body made of black Teflon, making it suitable for UV-curable resin materials and anaerobic resin materials. For more details, please contact us or refer to the catalog.
