The Sun Hydraulics DMDALNV536 (DMDALNV536) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. Engineered for robust and efficient operation, this valve is capable of handling maximum operating pressures up to 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). Its quick response time of typically 50 ms ensures rapid actuation and control in hydraulic circuits. The DMDALNV536 is particularly noted for its closed transitions between spool positions B and R, which enhances performance by ensuring faster and more consistent response times, making it ideal for applications as pilot controls where capacity is less critical. The valve operates without the need for minimum hydraulic pressure, adding to its versatility in various system configurations. Equipped with EPDM seals, the DMDALNV536 is suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can degrade. The valve's wet armature design allows the working fluid to surround the armature, which may require consideration regarding heat dissipation during prolonged energization periods. For maintenance or manual control, the DMDALNV536 includes a manual override feature with a detent mechanism designed for temporary actuation. Its mechanical life expectancy is approximately 7,000 cycles. Additionally, the valve incorporates Sun\u2019s floating style construction to minimize internal part binding due to installation torque or machining variations. This model also supports interchangeable coils with other Sun Series 1 solenoid products for enhanced adaptability and ease of use in system design or replacement scenarios.

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.
