SUN CBGA-LHN Hydraulics check valve Counterbalance Valves Cartridges CBGG-LJN RDDA-LCN PRDB-LDN NFDD-LGN

This direct acting, solenoid-operated, 4-way, 3-position spool valve is spring centered to the neutral position. When coil A is
energized, the flow is from port 3 (P) to port 2 (A) and from port 4 (B) to port 1 (T). When coil B is energized, the flow is from
port 3 to port 4 and from port 2 to port 1.
* 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.
* In differential flow circuits, the higher return flow should be directed through port 2 (A) to port 1 (T).
* 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 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 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.
