The Sun Hydraulics DTCAZHN924 (DTCAZHN924) is a solenoid-operated, 2-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. This direct-acting, poppet-style valve is engineered to minimize leakage, even under sudden pressure changes, thanks to its robust construction. It features a position switch that provides confirmation when the valve is in the non-energized position, ensuring reliable operation. The valve requires a coil to be ordered separately and is supplied as a sealed unit that is not field serviceable; any modifications must be handled by returning it to the factory, as tampering voids the warranty. Installation requires specific tools due to the design of the position switch. Rated for fatigue at 5000 psi (350 bar), this valve excels in load-holding applications where it will reliably spring closed during power failures. It operates without needing minimum hydraulic pressure and incorporates a wet armature design that efficiently manages heat generated by the coil. This design consideration is important when using fluids like water-glycol mixtures that can degrade over time under high temperatures. The solenoid's magnetic design ensures high efficiency with significant actuating force per watt expended. The DTCAZHN924 also includes Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It fits into T-13A cavities and has a capacity of 6 gpm (23 L/min). With a quick response time of approximately 50 milliseconds and minimal leakage at maximum operating conditions, this valve supports high-frequency switching up to 15,000 cycles per hour. Its robust mechanical life expectancy of about 7,000 cycles makes it suitable for demanding applications requiring temporary manual actuation via D or L control mechanisms.

This solenoid-operated 2-way, 2-position cartridge is a direct-acting, poppet-style directional valve. Due to the poppet-style construction, this valve has extremely low leakage.
Many poppet style directional valves pass a small amount of fluid when the pressure across them changes suddenly. This is due to the compressibility of the fluid. This valve has been designed to prevent this from happening.
The position switch provides confirmation that the valve is in the non-energized position.
- A coil must be ordered with this cartridge. This cartridge is supplied as a sealed, factory set unit and is not field serviceable. If the assembly requires changes or service it needs to be returned to the factory. Any tampering will violate the product warranty.
- Position switch is CE approved.
- When torquing this cartridge into its cavity, a crow's foot wrench or similar will be required since the position switch precludes the use of a deep socket wrench.
- 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.
- This valve is suitable for load holding applications. In the event of power failure, the valve will spring closed.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- 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.
- 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.
- 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.
