The Sun Hydraulics DMDASPV72419 (DMDASPV72419) is a solenoid-operated, 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve features a unique soft shift mechanism that mitigates shock from valve actuation, enhancing system longevity and reducing potential damage from hydraulic spikes. However, it is crucial to note that this soft shift feature may not be suitable for applications requiring precise timing or ramping control. In such cases, Sun Hydraulics recommends considering their electro-proportional valves. The DMDASPV72419 model integrates a push-type manual override control and boasts compatibility with various manual controls which can be field-installed, except when combined with weatherized coils. The solenoid tube assembly of this model is fatigue rated for service up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. Designed with EPDM seals, the valve is specifically configured for use with phosphate ester fluids; exposure to petroleum-based fluids can compromise seal integrity. This valve also utilizes a wet armature design where the working fluid surrounds the armature. Prolonged energization of the coil should be monitored as it can lead to fluid breakdown in certain conditions, affecting cartridge function. The magnetic design of the solenoid in the DMDASPV72419 ensures high efficiency and effective spool actuating force per Watt expended. Furthermore, the construction style of this model minimizes internal part binding due to installation torque or cavity/cartridge machining variations, promoting consistent operation and ease of maintenance. With a maximum operating pressure capacity of 5000 psi (350 bar) and flow capacity up to 5 gpm (20 L/min), this valve addresses demanding hydraulic control needs effectively while maintaining environmental resilience with options for enhanced weatherized protection through additional coils and kits available for varying operational environments.

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.
