The Sun Hydraulics DNCAMTV72499 (DNCAMTV72499) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This directional valve is engineered with a closed transition between positions, which significantly minimizes oil loss during shifting\u2014an essential feature for pilot control circuits. The valve operates optimally with port 3 as the inlet and port 1 as the tank; while reverse flow is feasible, it is not recommended due to potential performance inconsistencies. With a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), this valve requires no minimum hydraulic pressure for operation and employs EPDM seals that are compatible with phosphate ester fluids but vulnerable to petroleum-based substances. Its wet armature design means the fluid surrounds the armature, potentially affecting performance if exposed to heat from prolonged coil energization. The DNCAMTV72499 offers various coil termination and voltage configurations, including options with surge protection. Its high-efficiency solenoid generates substantial spool actuating force per watt used, ensuring reliable valve shifting. Coils are interchangeable across Sun Series 1 solenoid products and can be mounted in either direction. The connector options provide protection ratings up to IP69K, with additional weatherized coils available for enhanced environmental resistance. This model incorporates Sun's floating style construction to minimize internal binding risks due to excessive torque or machining variations. It features a cavity T31A design within Series 1, supporting capacities up to 8 gpm (30 L/min) and operating pressures of up to 5000 psi (350 bar). The typical response time is approximately 50 ms, with a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The manual override requires a force of approximately 5 lbs at Port 1 under specific pressure conditions and has an override stroke of .10 inches (2.5 mm).

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.
