DCF-L Single-Fluid Solenoid Valve Nozzle

DCF-L Single-Fluid Solenoid Valve Nozzle provides precise liquid control through an integrated electromagnetic actuation system. Equipped with a 24V DC solenoid coil, it enables rapid opening and closing of the internal valve, allowing accurate intermittent spraying without the need for compressed air. This approach simplifies system configuration while maintaining stable and repeatable spray performance.

Robust structure is a key feature of DCF-L model. Compared with compact versions, it offers a stronger body and higher flow capacity, making it suitable for a wider range of industrial installations. With a standard 1/8″ threaded connection, it integrates easily into various piping systems and automated production lines, supporting flexible installation and operation.

DCF-L model focuses on stable fluid delivery and consistent spray performance. It supports high-frequency switching, allowing precise control of spray timing and liquid dosage. This helps reduce fluid waste while ensuring uniform application results in processes such as lubrication, coating, cooling, and general spraying. The nozzle maintains reliable operation even under continuous working conditions, delivering steady output over extended periods.

Materials used in DCF-L Single-Fluid Solenoid Valve Nozzle include stainless steel, PPS, and PEEK, providing excellent resistance to corrosion, wear, and chemical exposure. These materials enhance durability and ensure long service life in demanding industrial environments. Internal sealing components maintain tight shut-off performance, preventing leakage and ensuring clean and accurate spray cycles.

Maintenance is straightforward due to modular construction, allowing quick replacement of key components without complex disassembly. This reduces downtime and improves overall operational efficiency. Strong structure, stable performance, and reliable control make DCF-L model a practical solution for industrial automated spraying systems.

DCF-L Single-Fluid Solenoid Valve Nozzle is widely used in applications such as lubrication, cooling, coating, cleaning, and fluid dispensing, where stable spray performance and higher flow capability are required.

Fluid Connections

Fluid connections should be made using appropriate 1/8″ pipe connections. If metal fittings are used, an appropriate thread sealant should be applied to the threads prior to assembly. For those applications where recirculation is required, two 1/8″ pipe connection ports are provided. If recirculation is not required, one of the doors should be plugged using the 1/8″ pipe plug provided with each unit.

Electrical Connections

Electrical conduit connections for conduit fittings accept 1/2″ NPT(M) for NPT versions. Conduit must protect the cable from mechanical damage and terminate in a sealed enclosure or junction box suitable for hazardous locations. For BSPT versions, cable uses an Ex-D rated cable gland. Fuse holder and 3/10 amp fuse should be used as shown in Fiaure 1. The ground for the CY-DP-03-A must be connected to a true earth ground.

Operating Principle

When the coil is energized, a magnetic field is formed, and the electromagnetic coil generates electromagnetic force to lift the movable core upward, the sealing plug opens, and the liquid flows out from the sealing seat; when the power is off, the electromagnetic force disappears, and the spring behind the movable core presses the movable core onto the sealing seat, closing the liquid channel.

Applications

Spraying, belt spraying, cooling, gluing, lubrication, spray marking, moisturizing, distribution, glazing, laminating, robotic applications, marking, seasoning, humidification
