The Sun Hydraulics DNCATBV223 (DNCATBV223) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This directional valve is engineered with a closed transition between positions to significantly reduce oil loss during shifts, making it especially beneficial for pilot control circuits. The valve's capacity assumes port 3 as the inlet and port 1 as the tank; while reverse flow is possible, it may not meet the same performance standards and is thus not recommended. Designed for robust applications, the solenoid tube assembly can withstand up to 5000 psi (350 bar) service pressure without fatigue. This valve operates without requiring minimum hydraulic pressure due to its direct actuation mechanism. Notably, cartridges configured with EPDM seals are intended for use with phosphate ester fluids only; exposure to petroleum-based fluids will damage these seals. The wet armature design allows the working fluid to surround the armature, which can be affected by coil-generated heat over prolonged energization periods\u2014caution is advised when using water-glycol mixtures due to potential varnish formation. The DNCATBV223 offers various coil termination and voltage options, including models with surge protection. Its high-efficiency magnetic design ensures reliable valve shifting with high spool actuating force per watt expended. Coils compatible with other Sun Series 1 solenoid products are interchangeable and can be mounted in either direction on the tube. Coil connector options are available up to IP69K ratings for enhanced environmental protection. Additional features include Sun's floating style construction that reduces internal part binding risks due to installation torque or machining variations. This model supports a capacity of 8 gpm (30 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and a switching frequency of up to 15,000 cycles per hour.
