The Sun Hydraulics DTCAZHN812 (Material Number: DTCAZHN812) is a solenoid-operated, 2-way, 2-position cartridge valve featuring a direct-acting, poppet-style design. This configuration ensures extremely low leakage, even when the pressure across the valve changes suddenly, thanks to its fluid compressibility prevention mechanism. The valve comes with a position switch that confirms it is in the non-energized position and requires an additional coil for operation. It is factory-sealed and non-serviceable in the field; any necessary adjustments or servicing must be performed by returning it to the factory. The valve is CE-approved for its position switch and mandates specific installation tools due to its design constraints. This direct-actuated valve does not require minimum hydraulic pressure for operation, making it suitable for load-holding applications where it will spring closed during power failures. It features a wet armature design that allows working fluid to surround the armature, which can impact performance if energized for prolonged periods. The solenoid's magnetic design offers high efficiency with significant spool actuating force per watt expended, ensuring reliable shifting. The DTCAZHN812 incorporates Sun's floating style construction to minimize internal part binding risks due to excessive torque or machining variations. With a capacity of 6 gpm (23 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve has a typical response time of 50 ms and can handle up to 15,000 cycles per hour. It has a maximum leakage rate of 10 drops per minute at 5000 psi (0.7 cc/min at 350 bar). The cartridge fits into a T-13A cavity and requires an installation torque of 30-35 lbf\u00b7ft (41-47 Nm).

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.
