The Sun Hydraulics DMDASPV636 (DMDASPV636) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This model is specifically engineered to offer soft shift capabilities, which help in reducing shock during valve actuation. Although the soft shift feature slows the response time\u2014typically ranging from 150 ms to 300 ms\u2014it is significant in applications where shock reduction is more critical than timing precision. For precise control over ramping or timing, alternative electro-proportional valves are recommended. The DMDASPV636 incorporates a wet armature design, where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energized conditions. It\u2019s compatible with EPDM seals for systems using phosphate ester fluids but is unsuitable for exposure to petroleum-based fluids which can damage these seals. The valve's construction includes a push-type manual override and supports a maximum operating pressure of 5000 psi (350 bar). It also features an innovative magnetic design that enhances solenoid efficiency and ensures reliable spool actuation. This model comes with various coil connector options that can achieve ratings up to IP69K for enhanced environmental protection. The floating style construction of the valve minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. The manual override feature in this model does not support weatherized coils and has specific requirements for consistent performance. Overall, the Sun Hydraulics DMDASPV636 is designed for robust performance in hydraulic systems requiring efficient directional control and shock mitigation without the critical need for fast response times.

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.
