The Sun Hydraulics DMDASPV72499 (DMDASPV72499) is a solenoid-operated 3-way, 2-position cartridge valve that features direct-acting, balanced spool directional control. Designed for high-efficiency and reliable valve shifting, this model incorporates a unique magnetic design that maximizes spool actuating force per watt expended. It is particularly noted for its soft shift feature which significantly reduces shock from valve actuation, although it is not suited for applications requiring precise timing control due to its increased response time ranging between 150 ms to 300 ms. The DMDASPV72499 valve supports flow rates up to 5 gpm (20 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). It includes a push-type manual override control and features a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization can lead to fluid degradation in certain types of hydraulic fluids. The valve's construction uses Sun's floating style to minimize internal parts binding, enhancing durability and performance consistency. Sealing options with EPDM are available specifically for use with phosphate ester fluids, while exposure to petroleum-based fluids should be avoided as it damages the seals. Additional environmental protection can be achieved through optional weatherized coils and kits designed for more demanding conditions, with coil connector options offering ratings up to IP69K. In terms of physical specifications, the DMDASPV72499 has a solenoid tube diameter of .75 inches (19 mm), requires an installation torque of 30-35 lbf ft (41-47 Nm), and weighs approximately .60 lb (0.30 kg). This model is well-suited for various hydraulic applications where moderate flow rates and high-pressure capabilities are required but where exact timing is not critical.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The soft shift cartridge is interchangeable with the standard cartridge, however, the performance limits are lower.
- The soft shift feature can greatly reduce shock due to valve actuation but should not be counted upon in applications where timing is critical. If you need accurate ramping or timing control, consider Sun's electro-proportional valves.
- The soft shift feature results in significant increase in response time over Sun's standard solenoid. Response time is dependent on flow, pressure, coil voltage, oil viscosity and ambient temperature. Typical response time ranges from 150 ms to 300 ms.
- For consistent soft shift performance, port 1 should be at a positive pressure.
- This valve includes a push-type manual override control. Other manual control options such as T or D, cannot be ordered with the soft shift control but can be installed easily in the field. See Twist/Lock Manual Override link above for details. Please note: Manual override functionality is not compatible with weatherized coils.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- 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.
- 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.
- 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.
