The Yoshitake DP-16C is a normally opened, pilot-operated diaphragm type solenoid valve. It features stainless steel wetted parts, ensuring outstanding corrosion resistance and durability in demanding environments. Designed for versatile application, it reliably handles air, cold and hot water, and oil (20 cSt or less). The valve supports both horizontal and vertical installation, providing flexibility for various piping layouts.
