The Sun Hydraulics DMDASAV736 (DMDASAV736) is a solenoid-operated 3-way, 2-position cartridge valve, designed as a direct-acting, balanced spool directional valve. It features a soft shift option which moderates hydraulic shock during valve actuation, enhancing system longevity and reducing potential damage from abrupt pressure changes. This characteristic makes it suitable for applications where minimizing hydraulic shock is more critical than precise timing or ramp control. The soft shift model provides a slower response time compared to standard solenoids, with typical response times ranging from 150 ms to 300 ms depending on various factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. It is crucial that port 1 maintains positive pressure for consistent performance of the soft shift feature. The valve also includes a push-type manual override control which is not compatible with weatherized coils but can be replaced in the field with other manual controls if necessary. This model is fatigue rated for up to 5000 psi (350 bar) service and incorporates EPDM seals suitable for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it could damage the seals. The wet armature design of the solenoid means that the working fluid surrounds the armature which could lead to fluid degradation if exposed to heat for extended periods. Additionally, this valve benefits from Sun Hydraulics\u2019 floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating capacity of 5 gpm (20 L/min) and maximum operating pressure of 5000 psi (350 bar), this compact yet robust component ensures reliable operation and easy integration into various hydraulic systems.

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.
