Irritrol (Richdel) 2400 Series Solenoid Valves (25mm Flow Control/Slip/DC Latching)

The Irritrol (formerly Richdel) 2400 Series 25mm Solenoid Valve remains one of the most iconic and widely used irrigation valves in the world. First released in 1981 as the industry’s first-ever jar-top (screwless) solenoid valve, it revolutionised serviceability for contractors. Its patented design delivers fast, tool-free access to the diaphragm and internal components, making maintenance simple while ensuring long-term reliability.

Built for residential irrigation systems, the 2400 Series offers strong, proven performance with low friction losses, a heavy-duty UV-resistant PVC body, and a double-beaded Santoprene diaphragm for consistent sealing. Available in standard Female BSP, slip-fit, and flow-control models, the 2400 Series remains the preferred choice for designers, installers, and homeowners seeking dependable operation and long service life.

With both internal and external bleed options, an encapsulated solenoid, and corrosion-resistant components, the Irritrol 2400 Series is designed for easy installation and service without removing the valve from the line. Whether you're upgrading an existing system or installing a new one, this valve continues to set the standard for simplicity, durability, and dependable irrigation control.
