Product Description

Original SUN DFDJ-MHN Cartridge Valve Hydraulic Valve
 

This solenoid controlled, 2-way, 2-position cartridge is a pilot-operated, poppet style directional valve with reverse free flow check. It is available in either a normally open or normally closed configuration. Due to its poppet style construction, it has extremely low leakage.

This valve is designed to be used with 740 and 747 Series coils.

• The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
• Valves exhibit extremely low leakage rates; less than 10 drops/min. @ 5000 psi (0,7 cc/min @ 350 bar).
• Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
• All configurations of this valve include zinc-nickel plating as standard for 1000-hour salt fog protection.
• Coil connector options offer ratings up to IP69K. See individual coil product pages for details.
• This cartridge has an option for manual override. See the CONFIGURATION section.
• On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assemblies have a mechanical life expectancy of approximately 7,000 cycles.
• This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
• A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
• The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
• Coils can be mounted on the tube in either direction.
• Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
