DELCO Direct Acting Diaphragm Waterproof Solenoid Valve for Fountain-2W21
The direct-acting diaphragm solenoid valve, designed for use in underwater applications, is crafted from brass or stainless steel, offering excellent corrosion resistance and structural strength for reliable operation in harsh underwater conditions. This valve responds quickly and opens from 0 bar, boasting a high flow rate. Controlled by electromagnetic force that directly drives the diaphragm, it supports zero-pressure actuation. The solenoid coil is IP68 waterproof-rated, ensuring long-term performance underwater within a pressure range of 0 to 1.0 MPa (0 to 150 PSI). Voltage options include 12VDC, 24VDC, 110VAC, and 220VAC, catering to diverse electrical systems.
With port sizes ranging from 1/2″ to 2″ (DN15 to DN50), the 2W41 solenoid valve is suitable for handling medium-temperature media. The valve supports both threaded and flanged connections, facilitating flexible and straightforward installation across various piping systems. The 2W41 solenoid valve is ideal for enhancing the aesthetic appeal of landscape fountains or ensuring stable water flow in swimming pools. It offers efficient performance, reliability, and an extended service life, making it a popular choice in different fountain systems, including those in swimming pools and parks.

Working Principles:
When used in underwater applications, direct diaphragm solenoid valves utilize electromagnetic force to control the movement of a directly attached diaphragm mechanism. When the solenoid valve is energized, the solenoid coil generates a magnetic field that attracts or pushes the diaphragm, which opens or closes the valve for precise control of fluid flow. This design allows for pressureless operation, providing excellent water and corrosion resistance for applications requiring reliable underwater operation. utilize electromagnetic force to control the movement of a directly attached diaphragm mechanism.
