The Sun Hydraulics DNCAMAV71299 (DNCAMAV71299) 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 minimize oil loss during shifting, which is particularly beneficial in pilot control circuits. The valve's capacity is optimized when port 3 is used as the inlet and port 1 as the tank; while reverse flow is possible, it may not guarantee the same performance and is therefore not advised. It boasts a solenoid tube assembly fatigue rated for up to 5000 psi (350 bar), ensuring robust service life under demanding conditions. The valve requires no minimum hydraulic pressure for operation due to its direct actuation. This model accommodates systems using phosphate ester fluids with EPDM seals but should avoid petroleum-based fluids to prevent seal damage. Featuring a wet armature design, the working fluid envelops the armature and can be influenced by heat generated from prolonged coil energization, potentially affecting certain fluids like water-glycol mixtures over time. A variety of coil termination and voltage options are available, including configurations with surge protection. Its high-efficiency solenoid design provides significant spool actuating force per watt expended, ensuring reliable valve operation. The DNCAMAV71299 incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It supports capacities of up to 8 gpm (30 L/min) and operates at maximum pressures of 5000 psi (350 bar). The typical response time is around 50 ms, with a leakage rate at maximum operating conditions of 10 in\u00b3/min (160 cc/min). Manual override features include a force requirement of approximately 5 lbs/1000 psi and a stroke length of .10 inches (2.5 mm). Coils are interchangeable within Sun Series 1 products and offer IP69K-rated connector options for enhanced environmental protection.

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.
