The Sun Hydraulics DMDASRV236 (DMDASRV236) is a solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve features a soft shift option that moderates the shock typically associated with valve actuation. Although this soft shift feature slows the response time slightly\u2014typically ranging from 150 ms to 300 ms\u2014it enhances system longevity by reducing the impact of sudden pressure changes. The valve performs optimally when port 1 maintains positive pressure. Additionally, the DMDASRV236 includes a push-type manual override control which is not compatible with weatherized coils but can be substituted easily in the field with other manual controls like T or D options. The construction of this valve incorporates Sun's floating style design which minimizes internal parts binding, ensuring smooth operation even under varying installation torques and cavity/cartridge machining discrepancies. The solenoid tube assembly of the DMDASRV236 is fatigue rated for up to 5000 psi (350 bar), and it employs a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity over prolonged periods of energization. The unit is also configured to work with EPDM seals suitable for phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it damages the seals. This model supports a flow capacity up to 5 gpm (20 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). With its robust magnetic design, it ensures high efficiency and reliable valve shifting by maximizing spool actuating force per watt expended. For environments requiring additional protection, weatherized coils and kits are available separately.

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.
