The Sun Hydraulics DNCALZV71219 (DNCALZV71219) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This directional valve is engineered for seamless transitions between positions with a closed configuration to significantly reduce oil loss during shifts, which is particularly advantageous in pilot control circuits. Designed with port 3 as the inlet and port 1 as the tank, it maintains optimal performance in this orientation; reverse flow is possible but not recommended due to potential performance discrepancies. The valve's solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. It operates without requiring minimum hydraulic pressure and supports systems using phosphate ester fluids when configured with EPDM seals. The wet armature design allows the working fluid to absorb heat from the coil, necessitating consideration of fluid type and exposure duration to avoid varnish formation in some mixtures like water-glycol. The DNCALZV71219 offers diverse coil termination and voltage configurations, including options for surge protection. Its magnetic design enhances efficiency by delivering substantial spool actuating force per watt expended, ensuring reliable shifting. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bi-directionally on the tube. Additionally, coil connector options are available with ratings up to IP69K for robust environmental protection. The valve incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. With a capacity of 8 gpm (30 L/min), this valve supports a maximum operating pressure of 5000 psi (350 bar) and exhibits a typical response time of 50 ms. It features a manual override force requirement of 5 lbs/1000 psi at Port 1 and accommodates various seal kits for maintenance flexibility.

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.
