The Sun Hydraulics DNCALSV72499 (DNCALSV72499) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. With closed transition between positions, this valve effectively minimizes oil loss during shifting, making it particularly suitable for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; however, reverse flow is not recommended due to potential performance issues. Designed for robust operation, the solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), and the valve requires no minimum hydraulic pressure for activation. It incorporates EPDM seals compatible with phosphate ester fluids but unsuitable for petroleum-based fluids. The valve utilizes a wet armature design allowing the working fluid to cool the armature by surrounding it, although care must be taken with fluids like water-glycol mixtures that can degrade under prolonged heat exposure from the coil. The solenoid's magnetic design delivers high efficiency with significant spool actuating force per watt expended, ensuring reliable shifting. Various coil termination and voltage options are available, some offering surge protection and IP69K ratings for enhanced environmental resistance. This model features Sun's floating style construction to prevent binding from excessive installation torque or machining variations. It fits into a T-31A cavity and has a capacity of 8 gpm (30 L/min). Typical response time is around 50 ms, with maximum leakage at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports a switching frequency of up to 15,000 cycles per hour. Manual override requires minimal force and stroke length. The valve weighs approximately .60 lb (.30 kg) and includes Viton seal kits for both cartridge and coil components.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- 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.
- 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.
