This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool pilot valve used to pilot other
full-flow valves. The valve is normally open between port 1 and port 2 or port 1 and port 3 and all flow paths are
bidirectional.

DBAL
TECHNICAL FEATURES
Model DBAL integrates the same coil, connector, and manual override options that are currently available on Series 1 valves. The DBAL is interchangeable with the
DBAA except for the external coil dimensions and higher coil wattage.
The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
This valve is direct actuated and requires no minimum hydraulic pressure for operation.
NOTES
Please verify cartridge clearance requirements when choosing a Sun manifold. Different valve controls and coils require different clearances.
An additional 2.00 inches (50,8 mm) beyond the valve extension is needed for coil installation and removal.

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
assembly has a mechanical life expectancy of approximately 7,000 cycles.
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.
This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is
not compatible with weatherized coils.
Valves exhibit extremely low leakage rates; less than 10 drops/min. @ 5000 psi (0,7 cc/min @ 350 bar).
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.
Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete
environmental protection.
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.
