DCF-M Dual-Fluid Solenoid Valve Nozzle

DCF-M Dual-Fluid Solenoid Valve Nozzle uses compressed air and liquid together to achieve fine and controllable atomization. Compared with single-fluid nozzles, this structure produces smaller and more uniform droplets, improving spray quality and coverage while reducing liquid consumption.

A 24V DC solenoid coil controls the internal valve, enabling rapid on-off switching and accurate intermittent spraying. This allows precise control of spray timing and dosage, ensuring stable and repeatable performance in automated systems. High-frequency operation supports continuous production processes with consistent output.

Air and liquid are supplied separately and can be adjusted independently. By changing air pressure or liquid flow rate, droplet size, spray angle and atomization intensity can be easily controlled. This flexibility allows the nozzle to adapt to different process requirements, from fine mist generation to directional spraying.

Durable materials such as stainless steel, PPS, PEEK, and high-performance sealing components provide resistance to corrosion, wear, and high temperatures. This ensures reliable operation in demanding industrial environments. Standard threaded connections allow easy integration into existing systems, while modular construction simplifies maintenance and part replacement.

DCF-M Dual-Fluid Solenoid Valve Nozzle is widely used in coating, humidification, lubrication, cooling, and chemical spraying processes. It is especially suitable for applications requiring fine atomization, uniform coverage, and precise fluid control.

Fluid Connections

Fluid connections should be made using appropriate 1/4″ 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 1/4″ pipe connection ports are provided. If recirculation is not required, one of the doors should be plugged using the 1/4″ pipe plug provided with each unit.

Electrical Connections

Electrical conduit connections for conduit fittings accept 1/2″ NPT(M) for NPT versions. The conduit must protect the cable from mechanical damage and terminate in a sealed enclosure or junction box suitable for hazardous locations. For BSPT versions, the cable uses an Ex-D rated cable gland. The 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.
