This FLeX Series solenoid-operated 3-way, 2-position cartridge is a direct-acting, poppet-style directional valve. Due to the poppet style construction, this valve has extremely low leakage.

• This valve is direct actuated and requires no minimum hydraulic pressure for operation.
• Suitable for load-holding applications when configured as Normally Closed. In the event of power failure, the valve will close.
• Port 3 is the preferred inlet for this valve. Port 1 is limited to half capacity.
• Designed and tested to 10-million operational cycles at full-rated pressure.
• Exceeds new NFPA test standard T2.6.1 R2014 for fatigue and burst pressure ratings.
• Designed using CFD simulation for optimized geometries.
• 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 valve exhibits extremely low leakage - 0.004 in3 (0,07 cc)/min (1 drop/min).
• Manual push-version override options are available in the "A" poppet configurations (DWBF-*A*). The force on the "M" manual override must not exceed 25 lbf (110 N).
• 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.
• A FULL DATA SHEET is available for this model using the link at the top of the page.
• 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.
• 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.
