SLDF Series Under Water Fountain Solenoid Valve
The SLDF series solenoid valve provides reliable on-off control of fluid media in automatic control systems. It is specially designed for music fountains and dancing fountain applications, ensuring smooth and precise water control.
This series adopts a direct-acting, diaphragm-type structure, utilizing pressure differential to open the valve. It offers rapid response, stable performance, easy installation, and long service life. The valve is built with forged brass, cast brass, or cast iron for excellent durability and strong anti-clogging capability, making it suitable for long-term use in rivers, lakes, seawater, and other artificial water environments.
