The Sun Hydraulics DMDASRV736 (DMDASRV736) is a solenoid-operated 3-way, 2-position cartridge that functions as a direct-acting, balanced spool directional valve. This model features a soft shift option designed to mitigate shock from valve actuation, enhancing system longevity and performance stability. It is important to note, however, that for applications requiring precise timing control, Sun's electro-proportional valves might be more appropriate due to the increased response time associated with the soft shift design. Typical response times for this model range between 150 ms to 300 ms, influenced by factors such as flow rate, pressure, coil voltage, oil viscosity, and ambient temperature. The DMDASRV736 is engineered with a push-type manual override control and incorporates Sun's floating style construction which helps prevent internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. The valve's maximum operating parameters include a pressure rating of up to 5000 psi (350 bar) and a flow capacity of 5 gpm (20 L/min). Additionally, it features EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. For environmental protection and operational reliability in various conditions, the valve offers multiple coil connector options with ratings up to IP69K. The solenoid tube assembly is fatigue rated for robust performance under high-pressure conditions. This model also benefits from an innovative magnetic design that enhances solenoid efficiency and ensures effective spool actuation force per Watt expended. With its versatile design and advanced features, the DMDASRV736 is ideal for applications where smooth operation and reduced hydraulic shock are 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.
