The Sun Hydraulics DMDATRV912 (DMDATRV912) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is specifically engineered for robust and efficient functionality with a rated fatigue pressure of 5000 psi (350 bar), making it suitable for demanding hydraulic applications. The valve operates with no minimum hydraulic pressure requirement, which enhances its versatility in various system configurations. This model incorporates a closed transition between spool positions B and R, optimizing performance by allowing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The DMDATRV912 can handle a flow capacity of up to 12 gpm (45 L/min) and features rapid response times typically around 50 ms. For manual override operations, the valve includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. It also supports interchangeable coils with other Sun Series 1 solenoid products, which can be mounted in either direction on the tube for increased flexibility in installation. The construction of the DMDATRV912 uses Sun's floating style to minimize internal part binding due to installation torque or variations in cavity/cartridge machining. Additionally, models equipped with EPDM seals are intended for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. This valve's wet armature design means that the working fluid surrounds the armature\u2014important to consider as prolonged coil energization could lead to fluid degradation at high temperatures. Overall, the Sun Hydraulics DMDATRV912 offers reliable performance and durability for specialized hydraulic system applications.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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.
- 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.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- 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.
