The Sun Hydraulics DNCALBV528 (DNCALBV528) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to ensure minimal oil loss during position transitions due to its closed transition feature. This characteristic is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. The DNCALBV528 valve can handle a flow capacity of 8 gpm/30 L/min with maximum operating pressures up to 5000 psi/350 bar, making it robust for various hydraulic applications. This versatile valve features a solenoid tube assembly that is fatigue-rated for demanding conditions and does not require minimum hydraulic pressure to operate. It incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The wet armature design of the DNCALBV528 allows the working fluid to surround the armature which could be a consideration if the coil remains energized over extended periods. For adaptability in different system requirements, the DNCALBV528 offers a range of coil termination and voltage options, including models with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be installed in either direction on the tube. Additionally, connector options for these coils can meet IP69K standards for high-level environmental protection. The construction of the DNCALBV528 utilizes Sun\u2019s floating style design which helps prevent internal parts binding that might occur due to excessive installation torque or variations in cavity/cartridge machining. This design feature enhances the reliability and longevity of the valve in various installation contexts. With its rapid response time and capability to handle frequent switching cycles (up to 15,000 cycles/hr), this valve is engineered for performance and durability in challenging industrial environments.
